FAQs
What Are RNG Plastics?
RNG Plastics are renewable fossil fuel plastics that are fully converted / upcycled into renewable natural gas (RNG) at EPA regulated landfills. RNG is the same feedstock used to make virgin plastics.
Why Is the Technology Beneficial?
RNG Plastics represent the highest plastic sustainability model on Earth. RNG Plastics are a true circular economy model with verified carbon footprint reductions, as certified by an Intertek LCA. It is a mass balance plastic supporting U.S. federal initiatives.
What Are the Carbon Footprint Benefits?
Enables carbon offsets through RNG renewal, with estimated stacked credit values up to $200-$400 per ton (Verra 2026 projections, based on methodologies like VM0018 for methane avoidance and waste attributes). Supply chain stakeholders (manufacturers, packers, distributors, end-users) can apply these to meet their environmental objectives.
How Are they Made?
Manufacturers can seamlessly convert all compatible plastic types (e.g., PE, PET, PP, and multi-layer constructs) by supplementing their current resins with a small amount of RNG Plastics' proprietary EPS Resin (Enhanced Polymeric Structure). In EPA regulated landfills, it passively enables plastic to convert back into RNG.
How Does the Supplemental EPS Resin Work in a Plastic Product?
It remains dormant and has no effect on the plastic's properties, such as rip and tear resistance, dart drop, OTR, or haze. After the product reaches the EPA regulated landfill, the technology is activated during Phases III and IV and the methane (natural gas) is safely captured - along with that of organic waste.
How Does the Plastic Get Converted into RNG at Landfills?
EPA regulated landfills are multi-million dollar recovery centers. Waste, including plastics, can sit dormant for up to four years in a tightly covered, sealed environment to prevent pre-release of greenhouse gases (GHG). Giant wells are then drilled, which creates a high heat biodigester environment with built-up aerobic gases (primarily CO2). The escaping gases are primarily from bioplastic and contaminated organic materials. These wells are capped and the gases are then safely captured and diverted to an adjacent facility, avoiding atmospheric release. The landfill heats up to as much as 130°F, initiating a conversion into an anaerobic process that converts waste into methane (RNG) for up to 30 years. During this phase, RNG Plastics are renewed into their original feedstock—natural gas—with no pre-release of GHG. Traditional plastics remain buried with minimal conversion. Converts to RNG (methane) at 70-95% capture efficiency per EPA LMOP, yielding ~0.5-1 m³ per kg plastic based on ASTM and LCA testing.
Are there Microplastic, Toxins or Waste Left Behind?
No. Zero-contamination goals are met with REACH/FDA approvals and is supported by 2025 research on zero nano- and micro-contamination. After about 7-10 years or so, all that remains is a little water vapor and a tiny amount of biomass.
Are RNG Plastics Recyclable?
Yes. But why? All recycled plastics are downcycled, contaminated - but the RNG Plastics' pathway through the EPA regulated landfill recovery centers is upcycled with zero-contamination.
Are they Certified?
Yes. ASTM certification is through our RNG Carbon Credit program with authorized labs, plus LCA certification through Intertek, the world's most highly respected carbon credit VVB. Certifications are backed by EPA methane capture records.
What Types of Plastics Can Use the Technology?
The RNG Plastic technologies are meticulously formulated with broad compatibility for most fossil fuel plastics. They are adaptable for laminates and dissimilar materials, with manufacturing stability up to 550˚F. The exclusions are silicones, bioplastics, and hybrids.
How much more does it cost?
May initially raise costs by 2-3 cents per pound, but rebate income and smartly reformulating your raw material can reduce costs below virgin resin.
Where can you buy RNG Plastic EPS Resins?
In North America and Asia, you can purchase from distributors like Landfill-Safe LLC. They are sold to licensed manufacturers.
