INVESTOR PRESENTATION / OCTOBER 2023 LANDFILL BIODEGRADATION PEL'S STAGES OF USE TO END-OF-LIFE 01 Standard Use • • PolyEarthylene™ manufactured and sold to customer. Resin retains standard polyolefin properties, no change in performance following conversion into product and regular use. PEL is shelf-stable and will not degrade during normal use or on the shelf. 02 Disposal • User disposes product. If product is not recycled, then natural microbial attachment at surface begins in landfill, industrial composting facility or by the side of the road. Bacteria create hydrophilic surface using protein attachment. 03 Bacteria Formation Bacteria coat and colonize surface in continuous film. Bacteria implement peroxidase and other enzymes to break polyolefin bonds at surface. 04 Bacteria Proliferation Through chain scission and oxidation polyolefin chains are shortened. • Material softens and becomes waxy but does not disintegrate. • Molecular weight is reduced. 05 End of Life • Plastic hydrocarbons are transformed to CO2, water, methane and biomass. • • Inorganic component becomes part of the soil. No microplastics generated during process due to a complete breakdown of PEL. 12
