Animal wastes such as COW DUNG, POULTRY / CHICKEN LITTER, PIG MANURE etc. are valuable source of nutrients and renewable energy. However, most of the waste is collected in lagoons or left to decompose in the open which pose a significant environmental hazard. The air pollutants emitted from manure include Methane, Nitrous oxide, Ammonia, Hydrogen Sulphide, Volatile Organic Compounds and particulate matter, which can cause serious environmental concerns and health problems.

Anaerobic digestion (AD) is considered as one of the most important and advantageous processes for animal waste treatment. It will reduce the environmental hazards, while at the same time providing biogas for local energy needs.

We provide solutions for all kind of animal wastes to bio-energy. This starts from Planning, Designing, Construction, Commissioning and Operation of Biogas Plants with CDM solutions.

There are various types of reactors. Design available for converting waste into energy like ZPHBTM - (Continuous Stirred Tank Reactor) & ZPHBTM -(Gas Mixing technologies) are provided for treating animal wastes to biogas. We provide tailor made system to our client for CHP / Bottling / Injection based on site conditions and requirements. This technology is either Mesophilic / Thermophilic process for both CSTR / Gas Mixing technologies.



Our CSTR technology mixers are designed such a way that complete homogenization takes places inside the reactor for better performance and higher biogas production with less energy. We use special recirculation pumps with Gas Mixing along with liquid for recirculation into reactor for better mixing and more gas production from the wastes.


Effluent generated from the factory, will be collected in Collection tank / Pre-Hydrolysis tank where complete mixing taking place by agitator provided in the tank from then pumped to reactor through pump with chipping / macerator arrangement and after digestion overflow will be taken into sludge holding tank from then pumped to Screw Press/ Centrifuge for separation of bio-solids.

The solids and liquid will be used as fertilizer / land application. Part of liquid waste water will be reused for mixing of raw wastes water. Gas will be collected in Membrane type gas holder then pumped to Biogas engine after removal of H2S to produce electricity or biogas will be upgraded/ bottling will be done after removal of CO2 and other impurities. If required, we will mix different solid wastes based on local availability for proper C/N ratio and smooth operation of the plant continuously without any issues. Our systems are simple and easy to operate through PLC/SCADA automation for monitoring of the plant.
