This disclosure provides a composting system and method. The system comprises: (a) a container configured to contain a composition and comprising (i) insulated walls, (ii) an air intake and (iii) a vent; and (b) a composition contained in the container. The composition comprises aerobic microorganisms, a carbon source and a nutrient source sufficient to support growth of the aerobic microorganisms. The container is sufficiently insulated so that heat generated by aerobic respiration is sufficiently retained in the container to maintain a heat gradient in the container. The container is dimensioned to generate a stack effect that moves air into the air intake, through the composition and out the vent. The moving air provides oxygen to support growth of aerobic microorganisms, making the stack effect self-sustaining as long as a carbon source and nutrients last. The insulation can maintain temperatures in the composting cell sufficient to kill pathogenic microorganisms.

A method for improved anaerobic digestion is presented. The method includes mixing a volume of waste material with water to form a feedstock mixture. The volume of waste material includes an initial amount of biomass and the feedstock mixture includes methanogenic bacteria either naturally present in the waste material or introduced artificially. The method also includes introducing one or more promoter substances to the feedstock mixture. The one or more promoter substances are capable of modifying the methanogenic bacteria. Modifying includes stimulating novel enzyme production in the methanogenic bacteria.

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.

The Biopowerplant is a system that integrates the generation of carbon-neutral energy through the cultivation and conversion of microalgal biomass, with sewage sanitation and environmental carbon recovery, with the additional and secondary production of biofertilizer, biofuel, water for reuse. This system integrates a suboptimal anaerobic digestion subsystem focused on the generation of biogas, the processing of the resulting digestate through a microalgal consortium culture subsystem with biofilm induction and smooth decreasing gradient of light radiation, and the transformation of the generated microalgal biomass into syngas through a subsystem of evaporation, torrefaction, pyrolysis, gasification, and combustion in separate chambers. The syngas and methane from the biogas are subsequently used as fuel in an electric power generator capable of operating with mixed gases. The biogas generation process is enriched through the recirculation of the microalgal biomass supernatant, the residual heat from the syngas generation subsystem, and the heat transferred from the combustion gases of the electric generator. The residual sludge from the biogas generation subsystem is recirculated towards a longitudinal biopile subsystem, where it acts as an anaerobic medium compared to the aerobic medium that constitutes the concentrated microalgal biomass, and both streams are mixed to be transformed into the syngas generation subsystem. Input inflows for system operation are mainly sewage, and optionally seawater and/or leachate. The inflows must be bioaugmented with a microalgal consortium dosed automatically by a Compact in situ bioaugmentation system, preferably more than 3 kilometers before the inflow enters the system.

A method for producing an organic nutrient slurry from organic material containing at least one of animal material and plant material is provided. The method includes introducing the organic material into a pressurized reactor and subjecting the organic material to agitation and saturated steam at a temperature and pressure within the pressurized reactor for a duration of time sufficient to thermally hydrolyze and denature the organic material into a denatured slurry having mineral particle sizes of less than 200 microns; conveying the denatured slurry and at least one microbial inoculant to an aerobic reactor to form a mixture therein; and introducing oxygen to the aerobic reactor to stimulate aerobic digestion of the mixture, while maintaining the mixture at a predetermined temperature range and predetermined pH range sufficient to support the aerobic digestion, in order to produce an organic nutrient slurry for plants.

A secured “smart” container is disclosed for collecting green waste products including operational functions for collection, video surveillance and monitoring capacity. The secured “smart” container may include one or more programmable logic controllers. Operational functions are performed by electrical components including sensors to determine green waste deposits characteristics and contents. Operational functions are further adapted to send and receive data, operationally wirelessly, and configured and adapted to utilize solar derived electric power and, optionally, electric power from other sources. Embodiments provide constant 24 hour/7 days a week video surveillance and alert monitoring capabilities. Disclosed systems and methods also include collection and transportation of waste contents from the container to a processing subsystem. Additionally, disclosed systems may also include a monitoring system for monitoring the collection of green waste product, delivery of the same to the processing subsystem and tracking to and throughout final processing of the green waste product and handling personnel.
