Regenerative Robust Gasification Creates Circularity For All Plastics and MSW

Regenerative Robust Gasification (RRG) is a comprehensive vision for all waste. "Robust" refers to the ability to accept unsorted waste, including all plastic films regardless of layers, metallization, filth, fitments, chlorine, PFOS, etc. without sorting. "Regenerative" refers to conversion of waste to versatile Eco-Methanol™ feedstock to produce new virgin products/plastics.

Regenerative Robust Gasification (RRG) offers a novel, practical approach to achieve circularity of all commercial plastic packaging, especially flexible films found in household waste. RRG offers robustness and versatility, which are both necessary for broad appeal and adoption as well as long-term viability. The Consortium for Waste Circularity's vision involves co-location of Robust Gasifiers at operating and/or closed landfill sites. RRG promises to simplify collection and sorting of waste, leading to elimination of duplicate collection and operation of separate material recovery facilities (MRFs). Since RRG can accept everything in household waste, "sorting" is changed to "selection" based upon demand. RRG compliments material specific (less robust) recycling methods by selecting only those materials that are best suited for those processes. The RRG process begins by sorting out inorganics, such as metals and glass. Then specific items/materials may be selected to support other forms of recycling based upon demand. Bio-based materials, such as food and yard waste, may also be diverted to digestion or composting, depending on availability of infrastructure, or may continue with the rest of the waste to be shredded and gasified to syngas. Resulting syngas is converted to post-consumer waste-derived methanol (Eco-Methanol™) immediately on-site. Eco-Methanol offers market versatility since most chemical companies source methanol for subsequent manufacturing. Eco-Methanol is "recycled content" demanded by brands and consumers. Eco-Methanol may be blended with methanol at rates that meet recycled content pledges. Through mass-balance certification, Eco-Methanol may be exchanged with methanol globally to avoid shipping costs and impacts, which is important for island and distant coastal nations. Commercial Methanol-to-Plastics manufacturers close the loop by converting Eco-Methanol into "virgin-again" plastic resins. No other solution offers the robustness to handle waste, or the flexibility to supply as many markets with recycled content. Robustness and flexibility are essential for long-term economic sustainability. RRG may be powered with renewables.
