The process for producing organic molecules from fermentable biomass includes a step of anaerobic fermentation (5) producing volatile fatty acids (6), these precursors being transformed into final organic molecules by non-fermentation means. It also includes at least the following steps: a) extracting (9) at least one portion of the volatile fatty acids from the fermentation medium in such a way that the production of fermentation metabolites by the microorganisms (M) is not affected, and introducing a portion of the liquid phase (11) containing microorganisms from the extraction (9), b) synthesizing (13) organic molecules from the fermentation metabolites or from the volatile fatty acids extracted in step a)-c) continuing steps a) to b) until the final molecules are obtained, in terms of amount and quality. The invention also relates to an installation for implementing the process.

A rotary composter includes a rotatable composting drum, a motor for rotating the drum, an aeration system for supplying air to the drum and an open-loop computerized controller for controlling one or both of the motor and the aeration system based on animal growth data. The rotary composter may also have a wireless nitrogen gas sensor for sensing an amount of nitrogen gas in the drum and a load cell for measuring a mass inside the drum to enable the controller to further control one or both of the motor and the aeration system based on signals from the nitrogen gas sensor and the load cell.

Disclosed are methods and systems for the conversion of poultry waste into useful products. Some embodiments are directed to a process for forming a product solution from poultry waste. The process includes providing a feedstock that contains greater than 60 percent poultry waste, and anaerobically digesting the feedstock to produce a digestate that has a solids content of about 5% to about 15% by weight. The process also includes separating and classifying the digestate into multiple high solids fractions and a first filtrate. The process also includes adding the high solids fractions to an acid solution to form a slurry that is then separated and classified into multiple second solids fractions and a second filtrate. The process also includes clarifying the first and second filtrates to produce a first and a second centrate. The process also includes mixing the first centrate with the second centrate to form the product solution.

A system for recovering fat, oil and grease (FOG) from wastewater has multiple annular flotation zones in a concentric configuration surrounding a central column to create progressively increasing surface areas for FOG and solid particles flotation. Each flotation zone may be equipped with an independent pressurized micro air and/or ozone bubbles distribution system. The FOG is recovered in the first flotation zone without chemical additions. Coagulant and flocculant may be added in the second flotation zone to maximize removals of biochemical oxygen demand (BOD), total suspended solids (TSS), and colloidal particulates and produce clear effluent. Magnesium chloride is added in the third flotation zone to remove phosphorus and to form struvite particulates that can be used as fertilizer. Since both organic loading and solid loading in the treated effluent are significantly reduced, poultry processing plants can more easily meet wastewater treatment plant discharge limits and avoid surcharges.

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.

Today's funeral practices are unsustainable, toxic, and polluting. Both cremation and the manufacture and transport of caskets, grave liners, and headstones emit greenhouse gas emissions into the atmosphere. In fact, the very last thing that most of us will do on this earth is poison it. As a response, a system and method called recomposition that gently and naturally returns humans to the earth after death.
