Systems and methods for sequestering carbon dioxide from the environment using biopolymers are disclosed. The methods include forming consumer products using bioplastics or biopolymers, collecting said consumer products after consumer use and stopping biodegradation of said biopolymer. In some embodiments the biopolymer is a non-biodegradable biopolymer while in other embodiments the degradation of the biopolymer is stopped by alternative means. A tracking system of the fate of the bioplastic or biopolymer during the lifecycle of the product is described.

This document relates to methods for degrading Low Density Polyethylene (LDPE) and remediating leachate. This document provides methods involved in contacting pretreated LDPE or plastic waste comprising LDPE with at least one white-rot fungus, achieving near 100% LDPE degradation.

A method and system for coal ash reclamation from a land fill, the system comprising: a harvester; a screen for screening non-ash material from ash collected by the harvester; a dryer for drying raw ash thereby creating dried coal ash and fine particulate ash; an exhaust pipe to direct the ash to a dust collector; a crusher for crushing the dried ash; a classifier for classifying the crushed dried ash; and a storage container for storage. The method comprising: harvesting raw coal ash from a land fill; screening the raw coal ash to remove oversize materials; drying the screened ash to remove water; crushing the stream of dried ash; classifying the crushed ash into fine particulate ash and large particulate ash, the second stream being directed for further crushing; streams of fine particulate ash being cooled; and storing the fine particulate ash.

An entirely water-based, energy self-sufficient, integrated in-line waste management system is provided for comprehensive conversion of all organic fractions of municipal and wider community waste to fuels suitable for use in transportation, with all solid residues converted to high nutrition compost. The system is based on a combination of pre-treatment, involving alkaline hydrolysis and saponification; three-way separation of the pre-treated waste into different streams that are each directed to suitable further processing including fuel production; which includes biodiesel generation in a continuous-flow catalytic esterification unit, and anaerobic digestion to produce methane or other small molecule biofuel. Remaining solids are converted to compost in a quasi-continuous process.

This disclosure relates to a method and a system for sequestering carbon-containing materials in underground wells. An example method includes: obtaining a material comprising a carbon-containing liquid; optionally testing the material for compatibility with an underground well; optionally adjusting a property of the material to improve the compatibility; and providing the material for injection into the underground well.

Clean, safe and efficient methods, systems, and processes for utilizing thermolysis methods to processes to convert various carpet, rug, polymeric materials and other waste sources, such as solid waste, tires, manure, auto shredder residue, glass and carbon fiber composite materials, municipal solid wastes, medical wastes, waste wood and the like into a Clean Fuel Gas and Char source are disclosed. The invention processes the carpet, rug, polymeric material to effectively shred and/or grind the waste source, such as post-consumer carpet remnants and waste, and then process using thermolysis methods to destroy and/or separate halogen and other dangerous components to provide a Clean Fuel Gas and Char source. Additional waste sources, such as solid waste, tires, manure, auto shredder residue, glass and carbon fiber composite materials, municipal solid wastes, medical wastes, waste wood and the like, are suitable for the processing of the invention disclosed.

Existing approaches to refuse handling are all based on historical approaches which rely on a network of refuse collection vehicles collecting waste from individual households and delivering this to a centralised landfill or MBI location. This is highly undesirable and wasteful. An alternative process is disclosed, relying on the thermal treatment of waste and like products produced or brought in to the residential property and processed within the domestic curtilage to produce fuel or other forms of energy. Thus, domestic waste will be thermally treated at the home instead of being collected by local authorities and disposed of. The waste input put material will be loaded into a domestically engineered thermal conversion unit either directly or after a pre-process such as shredding. The feedstock will be converted into fuels by a thermal treatment, such as pyrolysis. The resultant output of oil and gas can either be stored or fed into a boiler unit to be used as a fuel to produce hot water, or used to run an electricity generating unit to power the dwelling in question or for supply to a feed-in tariff. Thus, a domestic dwelling includes a thermal treatment unit for processing waste produced in the dwelling, an output of the thermal treatment unit being combusted for producing an energy output for the dwelling. A suitable pyrolysis chamber is disclosed.
