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 gardenedging.



Nomacorc recently completed its first full Life Cycle Analysis (LCA) study on its flagship Nomacorc Classic+ product. The study’s results show significant improvements (read below):

  • 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

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
