The invention discloses a device for producing biogas with high methane content by utilizing livestock and poultry feces, wherein the interior of a tank body of a biogas fermentation tank is divided by a baffle, so as to form a main reaction chamber and an auxiliary reaction chamber which are communicated in upper portions, so that a reactant flows into the auxiliary reaction chamber only after entering the main reaction chamber via a relatively low feeding hole and then reaching a high position of a liquid level, and extension of fermentation time is realized, meanwhile, scales formed at the top of fermentation broth flow into the auxiliary reaction chamber along with liquid, so that the interior of the main reaction chamber keeps a liquid state all the time, and sealing and reduction of quantity of anaerobic bacteria are avoided.

According to present disclosure, there is disclosed an algae growth and cultivation system that provides a cost-efficient means of producing algae biomass as feedstock for algae-based products, such as, fertilizer, feed, biofuel manufacture, and desirably impacts, nutrient recovery from waste streams for valued byproducts production, recycle water, and alternative/renewable energy production. The system as discussed herein is an integrated systems approach to wastewater treatment, algal strains selection for byproducts production, and recycle of algal biomass-processing waste or additional algae harvested as feedstock for products such as fertilizer production. Embodiments of a system as discussed herein present an economically viable algae production system and process that allows algae-derived products such as fertilizer, feed, biofuels, etc. to compete with non-organic or petroleum products in the marketplace.

There is disclosed a method of producing a soil remediant from liquid organic waste material in which the liquid organic waste material is concurrently pasteurised and digested by thermophilic aerobic digestion in the liquid phase in a single digester vessel. The organic waste material in the digester is maintained continuously at a temperature of at least 70 C. for at least an hour and theliquid organic waste material comprises at least 70% water and can be pumped. After a period of at least an hour a small amount of pasteurised organic waste material is removed and a corresponding amount of fresh organic waste material is added to the single digester vessel such that the temperature is maintained in a comfort zone of the thermophilic bacteria. In a preferred embodiment the thermophilic aerobic digestion is facilitated by micro-organisms including crenarchaeota. The liquid organic waste material can be combined with a microporous adsorbent. Also disclosed is a soil remediant comprising a microporous adsorbent and liquid organic waste material from the novel method. The microporous adsorbent may be a volcaniclastic sedimentary rock or diatomite or of vegetable origin such as biochar. The microporous adsorbent may be a powder or a granular material and may have particle sizes up to 2000 microns.

A Biorefinery System (BIOSYS) that effectively treats all human activity-derived waste (black water, grey water, and food waste streams) using biological systems and that produces as process by-products: recovered potable water, liberated free oxygen, edible protein cake (with and without lipids), soil amendments, and machinery lube oils. Additionally, the system captures and chemically binds carbon dioxide into microbial cells and associated by-products, thus producing recovered usable returned cabin air.

A system and method for commercial production of aqueous Sargassum seaweed extract concentrate having arsenic level of around 1.32-15 mg/l; cadmium level of around 0.005-5 mg/l; lead level of around 0.2-12 mg/l; mercury level of around 0.00002-2 mg/l; and pH of around 7.4-9 is disclosed. The resulting seaweed extract concentrate can be used in plant and soil amendments, rooting hormones, other organic plant and soil amendments, organic fertilizers, adjuvants for use with organic pesticides, organic fungicides, in combinations of organic pesticides, with fungicides, and as fertilizers for agricultural, commercial and domestic use. The resulting seaweed extract concentrate can also be used to regulate plant growth, or as a plant nutrient. The method is believed to be able to prepare an extract concentrate from any high protein biomass, including Sargassum, water hyacinth or other seaweed.

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.
