Nomacorc is made from low-density polyethylene (LDPE) and  is classified as Resin Identification Code (RIC) #4, a commonly recycled material in many regions. However, recycling infrastructures for LDPE differ across geographies, which is why the specific RIC information is not always printed on the closure.
To facilitate higher rates of recycling of closures by consumers, wineries, and restaurants, Nomacorc has engaged in consumer recycling partnerships in the U.S. and France. We intend to expand those in the coming years. In addition, all scrap material that Nomacorc produces is sold to recyclers, who turn it into products such as toys, kayaks, rain barrels and garden edging.


Nomacorc recently completed its first full Life Cycle Analysis (LCA) study on its flagship Nomacorc Classic+ product. The study’s results show significant improvement across all environmental impact categories between 2008 and 20011 at both its U.S. and Belgium production facilities. Reasons for improvements include:

  • More efficient product formulation
  • Switching to local raw material suppliers
  • Shipping efficiencies
  • Increased use of renewable energy sources


The core LCA study measures the environmental impacts for every step of the life cycle of a Classic+ closure from “cradle” (raw materials extraction) to “gate” (the distribution of finished closures to customers). Significant improvements include:

  • A reduction of environmental impacts ranging from 13% to 92% for closures produced in Belgium between 2008 and 2001.
  • A reduction of impacts ranging from 10% to 23% across all environmental indicators for closures produced in the U.S. between 2008 and 2011

Nomacorc recently released its first-ever Corporate Social Responsibility (CSR) Report. Covering the 2011 calendar year, Nomacorc’s CSR outlines our approach to sustainability through three main guiding principles. Highlights from the report include:

Nomacorc is continuously implementing improvements in our operations and company culture to minimize our impact on the environment. In 2011, we:

  • Reduced raw material use by 13% globally, per closure produced
  • Reduced water use, per closure, by 18% globally by implementing process improvements
  • Reduced electricity consumption by 0.7% globally despite increased closure production
  • Introduced reusable containers for intra-company goods transport, reducing cardboard use by 22%, per closure produced
  • Grew consumer closure collection and recycling program for third straight year


An important goal is to calculate and reduce Nomacorc’s greenhouse gas (GHG) emissions on an annual basis. Intensive efforts to reduce product density have significantly decreased the carbon footprint of our corks from approximately 16g CO2-eq in 2007 to an estimated 11g CO2-eq in 2011. The majority of Nomacorc’s product carbon footprint is from raw materials.




Nomacorc’s foundation is the provision of consistent, high-quality closures that deliver an enjoyable consumer experience and serve the winemakers’ intentions. In 2011, Nomacorc:

  • Expanded our share of closure market
  • Grew overall unit sales for tenth consecutive year
Through our employee programs, Nomacorc endeavors to create a safe,supportive, and inspiring atmosphere in which our employees can thrive. In 2011, our team of approximately 500 employees:
  • Completed 16,042 hours of training
  • Donated 3,953 hours of community service
  • Had a voluntary turnover rate of only 1.9%
  • Received the following awards:
    • North Carolina Department of Labor (NCDOL) Gold Award (five consecutive years)
    • American Red Cross Certificate of Appreciation for Tornado Relief



Nearly all of the water used during manufacturing of Nomacorc closures is recycled or reclaimed and 100% of waste material created by the Nomacorc production process is recycled and converted to industrial products.

All Nomacorc closures are 100% recyclable with LDPE materials (US RIC 4). Because 90% of the environmental footprint of Nomacorc closures is due to raw materials used, every closure that is recycled has a corresponding 90% reduction in environmental impact.

To facilitate higher rates of recycling of closures by consumers, Nomacorc joined forces with Spec’s Wines, Spirits & Finer Foods of Texas to host The Cork Project. The Cork Project is a unique program with two simple goals: help save the earth by reducing the number of items in landfills and find a cure for cancer by raising money for research…one cork at a time. Recently, WidgetCo, a Houston-based recycler, joined The Cork Project to help ensure that the collected corks are recycled properly and that every cork will find a future.

Through the funds generated from the recycling and upcycling of natural and synthetic corks, The Cork Project was able to donate $10,000 to the CHRISTUS Stehlin Foundation, a world-class cancer research firm based in Houston. For more information on the program and donation, click here
