A system for producing biocoal and biochar includes at least one rotary compression unit (RCU) having a barrel, a compression screw housed within the barrel, a feed for receiving biomass and at least one exit for releasing biochar and gasses formed in the RCU. A first exit stream is produced that includes biochar and a portion of the remaining gasses, and a second exit stream is produced that includes biocoal. A gas crossover is provided that connects the first and second exit stream having a mechanism for transporting gasses from the first exit stream to the second exit stream thereby condensing a portion of the remaining gasses into the biocoal. In one form two RCUs are included connected to two condensers.

A method of producing an aromatic chemical, comprises: providing a feedstock comprising biomass to a first reactor to produce a first product stream, wherein the first product stream comprises methane and carbon dioxide; combining the first product stream with a recycle stream to form a second reactor feed stream; passing the second reactor feed stream through a second reactor to produce a second product stream comprising aromatics and hydrogen gas; recovering aromatics from the second product stream to create a recovery stream depleted of aromatics; combining the recovery stream with a stream comprising carbon dioxide to form a combined recovery stream; passing the combined recovery stream to a third reactor to produce the recycle stream comprising gas; and forming an aromatic chemical from the second product stream.

An apparatus for controlling water temperature includes a housing defining a composting chamber for receiving compost and a conduit disposed within the housing for providing flow of water. The conduit at least partially receives heat generated by the compost and may include a first subconduit extending substantially about an axis of the housing, a second subconduit extending substantially about the axis of the housing and being spaced apart from the first subconduit and a plurality of elongated subconduits extending between the first subconduit and the second subconduit and providing fluid communication therebetween. The housing may have at least one translucent portion for permitting flow of light waves therethrough. The apparatus may have a mechanism for mixing the compost.

The present invention is a composting bioreactor system that continually receives biodegradable solid wastes, waste waters and exhaust gases, automatically recycles the biodegradable wastes into nutrients and heat energy, and automatically supplies the nutrients and heat into an integrated hydroponic or aquaponic system. This invention together with integrated food growing system may be installed onsite such as balconies, backyards and premises of restaurants and food factories etc. therefore may lead to zero mileage targets both for recycling wastes and for supplying foods. This invention integrates composting process and aquaponic technology together and may establish a closed-loop recirculation of both water and gases therefore upgrades aquaponics into compoponics. A compoponic system has both soil and soilless growing beds and mimics nature recirculating nutrients, carbon and energy among human being, animals, microorganisms and plants by way of photosynthesis, slow burning by cellular respiration and burning by combustion.

A method and system is provided for treating water to remove contaminants using treated biochar placed in the water flow pathway of a water treatment process. The system further includes the further treatment of the treated biochar after its use in the water treatment process for use in agricultural or animal applications.

The present invention provides a delayed coking process comprising a step of subjecting a mixed feed comprises residual heavy hydrocarbon feedstock and bio oil obtained from fast pyrolysis of lignocellulosic biomass of one or more of Jatropha, Cashew nut, Karanjia and Neem to a delayed coking process and a system for the delayed coking process.

A method is provided for producing functionally improved carbolime from carbolime and the use of the functionally improved carbolime as a filtering aid, as filler, as lime fertilizer or as adsorbent for the adsorption of dyes.

The present invention refers to a process designed to increase the production of plant growth-promoting microorganisms of the Bacillus genus, using a culture medium poor in nutrients and with specific environmental conditions, allowing to obtain a greater amount of biomass and/or spores, which can be used to prepare solid or liquid compositions to be applied to plants, aiming to promote their growth and/or counteract the effect of phytopathogenic agents.

Methods, apparatus, and system for a compost system to reduce operator time, reduce power utilization, increase intensity of land use by the compost system, increase efficiency of biological activity in bulk material composted by the compost system, reduce odor production by the compost system, and to reuse water applied to and which may leach out of bulk material. The compost system may comprise an aerated pad, a pivot arm attached to a center of the aerated pad, and a control module. The aerated pad may receive a bulk material to be composted into a compost product. The aerated pad may comprise an air nozzle and a drain to direct water from the bulk material to a water collection system. The pivot arm may deposit the bulk material on the aerated pad. The control module may manage a temperature inside the bulk material using the air nozzle.

The disclosure relates to a composting device including a housing defining an interior with an access opening providing access to the interior, a composter bin located within the interior and in communication with the access opening, and a user operated door slidably mounted to the housing and electrically powered to automatically slide along a sliding path between opened and closed position.
