Diam Bouchage

With more than 1 billion closures sold annually around the world, DIAM Bouchage ranks as the leader in TCA free* cork  manufacturer's for the wine industry and is engaged in all major wine-producing countries.

Diam Bouchage is part of Oeneo group, which included Seguin Moreau cooperage, DIAM Bouchage produces a range of technological corks for still wines, sparkling wines and spirits.

As a leading innovator in developing effective wine closure solutions, DIAM Bouchage collaborates with some of the world's great viticulture institutions in both research and product development.

DIAM provides a secure closure with huge performance benefits, allowing our clients to close their wines with confidence. We have concentrated our efforts on two real threats to the wine industry: closure consistency with adapted OTR (Oxygen Transfer Ratio) and absence of released TCA.

Diam®, a tribute to the winegrower's art

Perfectly preserved aromas and flavours.

Although supercritical CO2 technology was already being used in some industrial applications (decaffeination, nicotine extraction from tobacco, etc.), it took 7 years of joint research with the CEA (French Atomic Energy Commission) before it could be applied to cork, thus giving rise to DIAMANT® technology, a proprietary cork taint removal process.

Thanks to DIAMANT® technology, the cork used in Diam® closures is free of flavour, void of TCA (the cork taint molecule) plus many other substances causing flavour modification. Stringent testing at every stage of

production means that Diam® is the only cork individually guaranteed free of releasable TCA (< than the measurable limit of

0.5 ng/l). The sensory purity and neutrality of Diam® closures protect all the wine's subtlest notes.

Total control over the way wine evolves.

Customised, tested permeability: Every wine has its own permeability requirements and nobody knows how much oxygen a wine needs better than the winemaker. The different versions of Diam® closures, give you total control over oxygen transfer and guarantees its constancy for the entire life of the wine in the bottle.

Consistency: The Diam® manufacturing process delivers perfectly consistent technical performance from one cork to the next. This provides smooth application at bottling, eliminates dust, suspended particles as well as leaking, seeping bottles and rising moisture. This consistency also has an impact on the way the wine evolves in the bottle: compared to other closures, Diam® provides the most even ageing in 5-year old wines from bottle to bottle (Aust. Wine Research Institute 2002 study).

Experience wine the way it was meant to be.

A Closure for Wines Committed to Quality and Sustainability

By Barbara Barrielle

Origine by DIAM, a 2018 WINnovation Award Winner

Diam OrigineFrancois Margot, North American Sales Manager for DIAM BOUCHAGE, has seen his company grow since launching their cork products 15 years ago, to be the second largest cork producer in the world and their presence in the American market is remarkable for a relatively young company.

To call DIAM a cork company is tells only part of the story. The technology they have developed relies on the efficiency of natural cork as a closure, but works to eliminate the inconsistencies in natural cork that can lead to flaws in wine.

“Naturally punched cork has been used for decades….centuries because it is an elastic product,” says Margot, “you put it in a bottle and it expands and seals. But the problem is that cork is inconsistent in three major ways.”

The first issue with natural cork is that it potentially contains molecules that will get into the wine that will cause what is called cork taint, so the producer runs a sensory risk of altering the taste of the wine.

The second issue is that the inconsistency of 100% punched natural cork allows a different amount of oxygen transfer into the wine.

And, lastly, the mechanical issue of differing elasticity means the seal from the cork may be compromised when the elasticity decreases over time and there is no way of knowing the long-term capability of the seal.

“So much more than a simple stopper, the cork is the last oenological act of the winegrower. It must enable the wine to fully develop in the bottle throughout the ageing period and maintain the aromatic profile sought for a particular wine,” explains DIAM CEO Dominique Tourneix. “This is why the teams at DIAM Bouchage work each and every day to ensure the quality of the company’s products in terms of mechanical performance, sensorial neutrality and oxygen control.” 

Diam Origine, Francois Margot

The scientists at DIAM still feel the base of natural cork is an excellent bottle stopper, but these inconsistencies could be eliminated by improving on the punched cork stopper. There is no shortage of cork in the world and using cork promotes the growth of the oak tree forests in the Mediterranean areas where it is harvested. Cork is regenerated quickly, every nine years, and Portugal and Spain make up eighty percent of the cork production.

DIAM takes the original inconsistent natural cork and extracts 150 different compounds to create a very clean cork that can control aromas and oxygen transfer.

Margot says that the Origine by DIAM goes a step further in creating a bio-based cork with the same properties that minimize inconsistencies. The Origine stopper combines natural cork along with a binding agent composed of 100% bio-based polyol from a totally renewable source. Years of research went into this sustainable product from an innovative ingredient – castor seeds – exclusively of plant origin that respects the environment and adheres to sustainable standards as does the cork harvest.

The third ingredient in the Origine by DIAM cork is pure, natural beeswax which is derived in a patented process to make corks totally watertight, protecting the wine against any capillary migration and protecting the integrity of the cork elasticity. Bees contribute hugely to our biodiversity and in recognition of this, DIAM Bouchage has decided to support an association dedicated to the preservation of the future of bees.

While DIAM corks can range from 12 to 80 cents per cork depending on the uniqueness of the product. Margot explain that Origine by DIAM will be more expensive and, therefore customers have been primarily producers of fine, more expensive wines.

“Origine by DIAM is very close to the performance of the traditional DIAM products but Origine is made from bio-based products,” says Margot, “and globally producers that want to go the biodynamic route will appreciate Origine by DIAM.”

Winemakers can have their corks customized depending on how much oxygen they want transferring through the cork and whether the cork needs an extended seal for aging or whether the wine is made to be drunk young. DIAM and Origine by DIAM give winemakers and wine producers options for wine stoppers while still promoting cork production and international biodynamics and respect for the future of the earth.

Diam Bouchage Introduces Origine® by Diam a New, Technologically Advanced Sustainable Cork
22 February, 2017

Made from Natural Ingredient Cork, Beeswax and 100% Vegetable Polyols

NAPA, Calif. (February 22, 2017) – Twelve years after launching its DIAMANT® technology, Diam Bouchage, a global leader in manufacturing technological corks, is once again ready to revolutionize the wine packaging world with Origine® by Diam, a new sustainable cork and major technological and environmental advancement.

“This new innovation offers a natural sealing solution while maintaining the proven reliability of Diam Bouchage in terms of guaranteed no detectable TCA, consistency and oxygen control,” said Francois Margot, Diam Bouchage Sales Manager for North America.

For years, Diam Bouchage’s Research & Development department has worked to develop new, environmentally-friendly products.  Today, after several years of research on natural ingredients, Diam Bouchage offers Origine by Diam, made from cork, beeswax emulsion and 100% vegetable polyols. This new technology is the result of research combining permeability and natural ingredients, and it responds to the demand from premium customers to create more open permeability closures that maintain the long life needed for aging wines. Currently, Origine by Diam will be offered for Diam 10 and Diam 30 closures in the Diam range for still wines.  In the near future, it will be extended to other closures offered by Diam Bouchage.

“The use of beeswax reflects our company’s commitment to green practices and products,” said Margot.  He added, “It is also reflected in the name we chose, Origine by Diam.   Pollination performed by honeybees is the basis of the biodiversity of our planet. With oxygen, it is the origin(e) of the life cycle of our cork oaks, and thus, our closures.  This is why Diam Bouchage is also contributing money to support critical habitats for bees by sponsoring hives in different French wine regions to help build and sustain bee populations.”

Diam Bouchage, a French company located in the Pyrenees Orientales, annually produces and sells more than 1.5 billion closures.  For more than 10 years, Diam has built its success on the revolutionary DIAMANT process that extracts TCA molecules* responsible for cork taint, as well as other molecules that can affect the taste of wine.

This Year’s “Wine Conversations: A Global Tasting and Marketing Forum” To Feature Costco’s Annette Alvarez-Peters as Keynote Speaker
19 January, 2017

MODESTO, CA, January 19, 2017 — What’s the secret to producing the best wine and, once it’s packaged, selling it through? To gain insights into those two key questions, plugged-in winemakers, wine marketers and winery purchasing professionals have marked their calendars for the fourth annual “Wine Conversations: A Global Tasting and Marketing Forum,” Monday, February 6, in Woodinville, WA, and Wednesday, February 8, in Santa Rosa, CA. This popular, efficiently-run event takes place from 10AM to 1PM, including lunch.

Hosted by DIAM Closures USA, part of global technical cork closure leader DIAM Bouchage, and their U.S. distributor G3 Enterprises, this annual event has fast attained “must-attend” status thanks to its ability to feature industry powerhouses whose insights can impact your bottom line. Costco’s principal wine buyer, Annette Alvarez-Peters, Assistant General Merchandise Manager for Beverage Alcohol, is this year’s keynote speaker. The other attraction is that the event is intimate enough for attendees to share ideas and experience a truly delightful global wine tasting. “What separates this event from others,” says DIAM’s North American Sales Manager François Margot, a trained winemaker himself, “is that this is not just a technical presentation — though we will be announcing an exciting new product. The focus is on fun and learning from one another. It’s all about tasting great wines and building the DIAM community.” Last year alone, over 1.5 billion bottles were sold with DIAM technical corks – closures formed from natural cork after being ground and treated with the patented DIAMANT® Super Critical CO2 process.

The conversation kicks off with an annual favorite: a double-blind tasting of 12 top quality wines from around the world, all closed with DIAM corks. Always a voyage of discovery, attendees are invited to take their best guesses as to the provenance and grape composition of the wines. Last year’s tasting included a surprising, top-quality wine from China. This year’s tasting will be led by Master Sommelier Evan Goldstein, who not only brings extensive knowledge to the table, but creates an entertaining environment that participants are sure to enjoy. In 1987, Goldstein became the eighth American — and at the time the youngest ever — to pass the prestigious Master Sommelier examination. He has since written several critically-acclaimed books, including Perfect PairingsDaring Pairings and Wines of South America: The Essential Guide.

Following the global tasting, two local winemakers will share some of their most valuable winery experiences and observations. At the Washington State event, guests will hear from winemakers John Bigelow, Owner of JM Cellars and Trey Busch, Co-owner of Sleight of Hand Cellars. At the Sonoma event Elena Franceschi, Associate Winemaker at Silverado Vineyards, and Rick Sayre, Senior VP Winemaking at Rodney Strong Vineyards, will present.

The keynote speaker at both forums will be Costco’s Annette Alvarez-Peters, who will share her latest insights on the current market. One of the most influential wine retailers in the U.S., Costco has been recognized as Retailer of the Year by Wine Enthusiast (2015), Washington State Wine Industry (2015) and Market Watch (2011). As chief wine buyer for the chain, Alvarez-Peters has been included on Decanter’s biennial Power List (2005-2013) and in Fortune magazine’s and Food &Wine magazine’s joint list of the 25 Most Innovative Women in Food and Drink (2014).

Demand for Diam 30 Closures Continues to Grow
21 January, 2016

New Factory and Strategic Partners are Keys to Meeting Demand

Diam30NAPA, Calif. (January 21, 2016) – In just two years since its introduction, Diam 30 has quickly become one of Diam Bouchage’s most successful closures with an average annual growth rate of 25% worldwide and sales in 18 countries around the world.  As a result, Diam opened a new factory in France last summer to support growing demand for their closures.

“When we introduced Diam 30, we knew its unique attributes and 30-year guarantee would quickly make it the closure of choice for winemakers and winery owners,” said Francois Margot, Diam Bouchage Sales Manager for North America and China. He added, “Diam 30 has surpassed every expectation to become an important alternative for many wineries.”

The closure was developed for high-end wines by Diam Bouchage after years of research. Diam 30 has one of the lowest permeability rates of any closure with a controlled oxygen intake on the market. Its manufacturing process guarantees winemakers absolute consistency from one closure to another which assures a slow, consistent aging process throughout the wine’s cellaring period. In addition, the patented DIAMANT® process means every Diam 30 closure can guarantee no cork TCA* and will guard against many other molecules that would result in off aromas or flavors.

“We are very proud of the number of outstanding wine brands using our closures. We appreciate our distribution partners who provide tremendous technical support critical to meeting the huge demand for Diam 30,” said Margot.

G3 Enterprises is the exclusive distributor of all Diam products in the United States, Canada and Mexico. As part of the growing demand for Diam closures, G3 Enterprises recently completed a series of upgrades to its cork room to boost capacity to produce high-quality Diam closures and to improve application consistency and efficiency. With the upgrades, G3 can now handle a batch range from 6,000 to 20,000 corks, improve coating application, ensure appropriate coating quantity, and reduce potential for mixed cork. In addition, G3 Enterprises offers best-in-class technical knowledge and sales support to make it very convenient for wineries throughout North America to access DIAM closures.

Diam Bouchage is a leader in manufacturing technological corks including Diam for still wines, Mytik for sparkling wines and Altop for spirits with options in wine aging potential, permeability, dimensions and branding.

Advanced Manufacturing Process Accelerates Demand
29 August, 2014

New facility in France set to expand production capacity to 2 Billion Diam, one of the undisputed leaders in the wine enclosure industry, has experienced an explosive U.S. sales expansion, while planning for even greater capacity once its new production facility comes on line in France next year.

Diam is the creator of an innovative beverage closure system, which begins with the raw bark of a cork oak. The bark is crushed and filtered to remove woody materials and then, through the Diamant procedure utilizing CO2, the compounds responsible for sensory deviations in wine, including trichloroanisole, (TCA) are extracted.

Diam-30“Natural cork has limits and some risks,” explains Francois Margot, Diam’s leading sales and export manager for North America. “There are a lot of molecules that can migrate into wine in a sensory way. DIAM has fixed that risk. We provide a 100 percent guarantee against TCA taint and a mechanical performance in our products that can exceed the shelf life of cork.”*

Margot points out that it is consistency “from bottle to bottle” that has excited winemakers around the globe and is responsible for doubling Diam’s market share in the U.S over the last two years. “We’ve seen an increasing number of wineries convert their entire production to Diam closures,” says Margot.

The company, which also makes closures for sparkling wine (Mytik) and spirits (Altop), has created a product for wine that can control oxygen transmission at three different levels; medium OTR (oxygen transfer rate) low OTR and very low OTR. This allows the winemaker to choose the closure that will fit the evolution of the wine. Their latest innovation, Diam 30, has a mechanical guarantee to remain elastic enough to preserve wine for at least 30 years.

“It is the first product on the market to give such a guarantee,” Margot asserts. “The key point here is security. The Diam 30 is made for high-end premium wines intended to age for years. We guarantee to bring the craftsmanship of the winemaker to the consumer in every bottle, with security even after 20, 25, or 30 years in the bottle.”

DIAM’s Spanish factories in San Vicente de Alcántara can churn out nearly 1.3 billion cork-product enclosures each year, and when the French facility in Céret is fully operational next June, capacity is expected to reach 2 billion closures.

Diam partners with G3 Enterprises, a leading packaging and logistics provider for the wine, spirits, microbrew and specialty food industries, in providing best customer services to wineries in North America. G3 finishes and prints Diam corks at its Modesto plant. “G3 has been a great partner. Their sales force and technical services are very strong. This allows us to focus on making quality products while G3 builds strong front relationships and supports our customers,” concluded Margot.

World’s Most Advanced Cork Closure To Debut in U.S. at Unified Wine and Grape Symposium
16 January, 2014

Diam 30 is the first cork closure with a 30-year lifetime

MODESTO, Calif.  (Janurary 14, 2014) – The new Diam 30, the world’s most advanced cork closure with the ability to last more than thirty years, will make its U.S. debut later this month at the Unified Wine and Grape Symposium in Sacramento.  Based on independent laboratory accelerated aging studies, the Diam 30 far surpasses the lifetime of natural corks.

“The Diam 30 is a new addition to our Diam range of closures and one of the most exciting developments in our industry. This innovation will help wineries avoid delicate, risky re-corking procedures after 20 years of cellaring,” said Dominique Tourneix, CEO Diam Bouchage. 

The closure was developed for high-end wines by Diam Bouchage after years of research.  Diam 30 has one of the lowest permeability rates of any closure on the market with a controlled oxygen intake.  Its manufacturing process guarantees absolute consistency from one closure to another which assures winemakers a slow, consistent aging process throughout the wine’s entire cellaring period.  In addition, the patented DIAMANT® process insures every Diam 30 closure will guarantee no cork TCA* and guard against many other molecules which result in off aromas or flavors. Diam 30 will be presented at the Diam booth #317 at the Unified Wine & Grape Symposium in Sacramento, California.

“The Diam 30 closure is perfect for the luxury wine market to safeguard wine throughout the aging process and to assure a consistent aging process,” said Mihailo Panovich, Vice President of sales for G3 Enterprises.  He added, “Given Diam’s cork technology and expertise, I am confident Diam 30 will be very successful in the U.S.”

Diam Bouchage is a leader in manufacturing technological corks including Diam for still wines, Mytik for sparkling wines and Altop for spirits.  Each year, the company sells more than one billion closures around the world.  G3 Enterprises, a leading packaging and logistics company for wine and spirits, is the sole distributor of Diam 30 and all Diam products in the United States.

About G3 and DIAM

G3, a leading packaging and logistics company for wine and spirits, is the sole distributor of DIAM products in the United States. DIAMANT Supercritical CO2 process is the patented technology by which raw, natural cork is cleaned and the optimal amount of taints and 150+ compounds from corkwood are removed, resulting in closures with TCA below the quantifiable detection of 0.3ng/L. DIAM provides clients an innovative and consistent solution for their wines by guaranteeing a technological cork free of TCA taint, for still and sparkling wine corks as well as DIAM-based bar top for liquor and spirits.


Cork Maker Regains Sparkle
22 October, 2012

Established in 1939 by an exiled Spanish journalist, the cork producer Oeneo has been through rocky times. But as Rebecca Gibb reports, it is now recovering some of its former strength.

Corks are popping at Oeneo, the company behind Diam closures, as another Champagne house, G.H.Mumm, joins the growing number of producers in the region moving away from natural cork. With an estimated one in six Champagne bottles now sealed with the technical closure, the French-owned company has come a long way since setting up as a natural cork producer at the end of the Spanish Civil War.

It all started when Modest Sabaté, a Spanish journalist, left his Catalan homeland in 1939 after Ferdinand Franco came to power. In his book "To Cork or Not to Cork," George Taber explains that having settled in France, Sabaté founded a cork company. He had heard that Champagne producers “were desperate to obtain a reliable supply of cork now that war and dictatorships had settled over the Iberian Peninsula.”

In 1960, Modest was joined by his eldest son, Augustin, and his three brothers, and the family business grew to become one of France’s leading cork producers. With growing concern about cork taint, the family patented a new cleaning process for cork and in 1995 they launched a hybrid part-natural, part-artificial cork named Altec. It was a huge success. By 2001, Sabaté had sold 2.5 billion Altec corks and half the company had been floated on the stock market during the dot.com boom.

The same year, however, the company's foundations were rocked by a public relations nightmare. Sabaté had promised that its Altec corks were free of the cork taint caused by a number of compounds, including 2,4,6-trichloroanisole or TCA. These taint compounds are produced by fungi naturally present in cork, or which have grown on the cork during its processing.

Despite Sabaté's claims, a growing number of disgruntled wineries were complaining that they were experiencing taint issues with Altec corks. A Wine Spectator report uncovered the problems and an international media circus ensued. In 2002, Modest’s grandson, Marc, stepped down from the company, ending the family's involvement with Sabaté.

Renamed Oeneo, the firm today is largely owned by Andromède, the holding group of the Cognac and spirits producer Rémy Martin. Other shareholders include an asset management firm, Amiral Gestion, and the financial services company Crédit Suisse.

With Altec corks tarnished by the scandal, Oeneo looked towards a new and improved closure. In 2004, it launched a TCA-free technical cork – Diamant – a project the Sabaté family had initiated in 1997. It is made from cork bark, but the firm uses a process which eradicates TCA. Even gas chromatography machines, which identify TCA at two parts per trillion – a level far more sensitive than the human nose – cannot find any trace of the compound after treatment.

Called the "supercritical" process, this revolutionary method is also used to decaffeinate coffee and to dry-clean contaminated military clothing. Oeneo uses the process to rid corks of all traceable levels of TCA and other undesirable compounds that can make wines seem less fresh than they ought to be.

The cork granules are cleaned using carbon dioxide (CO2) that is compressed to the point where it has the properties of both a gas and a liquid. This is the supercritical state in which the CO2 extracts the TCA-causing molecules from the granules. Two hours and 35,000 kilograms of CO2 later, 500kg of clean granules are ready to be baked into corks. Unlike natural cork granules, they have no smell. The granules are formed into corks with a binding agent – microspheres – which fill any gaps between them. The lowest grade of Diam has larger granules and more microspheres, which result in a faster rate of oxygen transmission and more rapid development in bottle. While unwelcome for fine wines, this faster aging is acceptable for wines that are expected to be drunk more quickly.

The wine world clearly likes these stoppers. Between 2008 and 2011, Diam production increased to one billion stoppers, and in the last three years Oeneo has spent 20 million euros ($26m) improving and expanding its production facilities.

“We have doubled the capacity of the factory, which is now at 1.3 billion corks per year, and we are thinking about more investment," says Bruno di Saizieu, vice president sales and marketing for Diam. "We know we will be at full capacity in the next 18 to 24 months.”

Di Saizieu puts the cost of this expansion at 40 to 50 million euros ($51–$64m), funded by shareholders. The Diam closures are replacing an improved version of the Altec corks, now renamed "Reference." By treating with steam, the Reference corks promise an 80 percent reduction in TCA, but there's no guarantee that it has been totally eradicated.

“We do have some markets that are not sensitive to TCA who use the Reference, like the beer market,” reports di Saizieu.

Oeneo estimates that three in 10 bottles of Burgundy are bottled under Diam and one in six of Champagne – a figure backed by the Comité Interprofessionnel du Vin de Champagne (CIVC). Many producers have moved towards cork alternatives not only because of cork taint, but also because Diam closures are consistent in their quality – unlike natural corks which vary. Each Diam closure comes with a guarantee, ranging from 2 to 15 years. Producers making a supermarket, drink-nowsauvignon blanc might opt for the two-year guarantee, while those producing high-end reds designed for cellaring would more likely opt for 10 or 15 years.

Winemakers can also choose the permeability of each cork. “The Diam 5 has two different permeabilities," explains di Saizieu. "In Burgundy, with pinot noir, you might want a tight closure, but with American wines, producers might want something a bit more open."

The ultimate goal is to produce closures according to individual markets: “Take a sauvignon blanc that is going to Japan. The Japanese would prefer a sauvignon blanc that is more open than the French, so you will use a different cork. Our goal is to increase our offer on permeability.”

One frequently mentioned criticism of Diam is that the closures don't look like traditional corks. Despite the number of bottles spoiled by natural corks, many consumers are still wedded to the real thing, particularly for high-end red wines. But Saizieu reports that in reality, most can't tell the two apart.

“We did a trial with a very nice Bordeaux wine. It was very interesting because we gave the bottles to people who knew about wine. We told them to take the cork out, taste the wine – they thought they were there to taste the wine. When they were tasting, we asked them: 'What do you think about the cork?' They hadn't noticed any difference.”

Despite the results of this trial, the company still felt compelled to manufacture a range of corks printed with a fake growth pattern to appease traditionalists.

In the early 2000s, at the height of its success, Oeneo (then still named Sabaté) boasted revenues of 202 million euros ($261m). This figure fell to less than 163 million euros ($211m) at the end of 2004. The company's latest annual results show it has not yet fully recovered from the Altec fallout, with profits reaching just 142.5 million euros in 2010–11.

But despite the overall drop, the closure division, Diam Bouchage (the company also has a barrel division), saw growth of more than 10 percent in 2010, suggesting that wine producers are putting their trust in its closures. Di Saizieu claims there are now 100-euro ($129) bottles of wine sealed under Diam, and the news that so many producers in Champagne have adopted it means the company is once more starting to shine.

Diam®, a tribute to the gift of nature

 Diam and nature

Cork is a noble material and a well-preserved ecosystem, at the heart of a sustainable economy.

Cork oak forests are a biotope specific to the westernMediterraneanand southern Atlantic seaboard.

The cork closure industry participates actively to maintain this ecosystem and, on a wider scale, the economies of the regions involved. Unlike alternative closure solutions, cork does not require huge amounts of energy to clean it and turn it into bottle closures.

Diam®, the ecological closure.

CO2, an inert, odourless, colourless and tasteless gas occurring abundantly in nature is the mainstay of the Diam® cork manufacturing process. To produce Diam® corks, it is used in a closed circuit (CO2 is recycled after undergoing purification). It does not react with foodstuffs or produce contaminating by-products. All these elements make supercritical CO2 processing a clean technology.

In addition, thanks to its bacteriostatic and antifungal properties, supercritical CO2 eliminates the need to wash cork with peroxide, thereby preserving the natural colour of cork and satisfying discerning users' environmental concerns.

Approved carbon budget: In 2004, Diam® was the first closure to undertake a carbon footprint in partnership with ADEME (the French Energy Performance Agency). This system aims at measuring the direct or induced greenhouse gas emission in order to optimise energy usage during manufacturing. From 2006 to 2008, Diam® reduced its overall carbon footprint by 12% and today implements an ongoing improvement process.

To further reduce its carbon footprint, and meet the environmental challenges of tomorrow, Diam® is implementing an in-house process focusing on four points:

  • energy performance
  • recycling corks by-products and all wastes
  • industrial risk and technical installation hazard control
  • investment in R&D for more environment-friendly products
