Biogas Plant

Biogas is an all-rounder among renewable energies. It can be converted to electricity and heat or be used as a fuel and natural gas equivalent.

Organic wastes such as live stock excreta and food residue pose a serious environmental risk in terms of air and groundwater pollution. KANKYO Biogas plants provide a proven solution to this problem by converting these materials into heat and electrical energy and leaving behind safe, environmentally friendly fertilizer.

Biogas is a combustible fuel which is produced through the anaerobic digestion process. Anaerobic means “in the absence of oxygen”. In the right set of circumstances, the organic fraction of liquid or solid biomass is converted into valuable fuel. Biogas consists of roughly 40% – 70% methane, with the rest being CO2 and trace amounts of H2O, H2S, H2 and NH3 produced by the microbiological process. The amount of methane in the biogas is largely a function of the organic input menu.

Liquid and solid manure, vegetable waste, grocery store waste, fats, oils, and greases (FOG), slaughterhouse waste, and selective energy crops, like corn, are ideally suited as inputs to a biogas plant. Biogas, when utilized in a combined heat and power (CHP) unit produces electrical energy for sale and heat energy for use locally. The heat produced by the CHP is used to heat the digestion process to improve biogas yield. Biogas can also be cleaned up for injection into the local natural gas grid or as a vehicle fuel.

The remaining byproduct of the digestion process is digestate which is a fermented organic material which may be used as high quality fertilizer. Biogas has a key role in supporting a diverse energy portfolio as a flexible, dispatchable fuel source.

Prefabricated Biogas Plant

Model BioPLUG
Our unique BioPLUG prefabricated biogas technology is highly efficient compared to the conventional systems and are modular in nature.The life cycle of the plant is 15 to 20 years and can be relocated anytime time anywhere. We provide the horizontal plug flow digesters and vertical prefabricated enameled tank digesters based on the size of the plant. We could generate power from biogas or we could produce BioCNG with which we can fuel the vehicles or use as an alternative to LPG for commercial cooking applications.

Model: Biomem

KANKYO has designed a new geo membrane biogas plants for the speedy installation of bio-waste to energy projects. Geo membrane biogas plants are fully pre-fabricated with specially developed synthetic materials to reduce the installation time. These plants are suitable for all types of lands and capable of installation on rooftops of buildings.

Model BioDry

Anaerobic digestion using input material that has moisture content less than 75%. KANKYO dry fermentation systems require no movement of organic matter or addition of liquid. No pre-treatment of biomass or organic waste is required.

Model: Bio TPAD

The Temperature Phased Anaerobic Digestion (TPAD) incorporates both thermophilic and mesophilic reactors connected in series to take advantage of the higher digestion rate of thermophilic digestion as well as the higher stability of the mesophilic digestion.

The thermophilic digestion rate is usually four times faster than the mesophilic digestion. On the other hand, adding a mesophilic digestion at the end not only improved stability of the digestion operation but also destroyed odorous compounds produced during the thermophilic stage.

Overall the TPAD process has greater volatile suspended solids (VSS) destruction and gas production ability.

It is reported that the VSS destruction efficiencies of the TPAD process are 15-25% greater than the single stage mesophilic digestion process. The TPAD process is also reported to have better shock absorbing capacity, lesser foaming issues and the ability to produce a ‘Class A’ biosolids

Model : Bioplus

Bioplus is a modified three-stage methane fermentation system that can produce methane from easily biodegradable waste was developed by us. This system uses a process that entails three stages: semi anaerobic hydrolysis/acidogenesis, strictly anaerobic acidogenesis, and strictly anaerobic methanogenesis.

This separate-reactor system efficiently decreases hydraulic retention time by increasing the rates of Microbe growth with in the digester by adding carrier material as the burnt brick, hydrolysis, acidogenesis and methanogenesis without affecting pH, and shows a high methane yield. The process adopted in this equipment is autocatalytic the immobilized bacterial column provided in the central column increases the microbial content.

The increased gas production in the central column creates a difference in density and the density and the density difference helps in better mixing. The mixing process adopted here eliminates the requirement of power.
