Straws and animal waste are used in this solution to produce biogas and organic fertilizer. This solution can not only reduce environmental pollution, but also bring great economic benefits in rural areas.
Henotec integrates advanced environmental technologies from Europe and China, a high concentration semi-dry anaerobic fermentation process based on China's rural conditions.It is aiming to propos effective comprehensive treatment and resource utilization of livestock muck and agricultural organic waste. The biogas project constructed by this process can be benefit as followed:
The high concentration semi-dry anaerobic fermentation process from Henotec, grafts the European technology on Chinese condition, provide effective treatment and resource utilization of animal and agricultural organic waste.
As an agricultural state, China has an annual output of 0.7 billion tons of straw, about half of the biomass resources. However, only 33% straw has been utilized in China. China is faced with the reality of high consumption, high pollution and low output of this resource. Especially, in the harvest season, straw is directly burned and produces SO2, NO2, CO, smoke and dust, etc. Meanwhile, manure is gradually replaced by chemical fertilizer in the modern agricultural industry. As a result, a lot of livestock muck could not be properly dealt with and may cause serious pollution to underground water and the environmental surrounding..
The Chinese countryside suffer badly air pollution because of directly burning of agricultural waste. Meanwhile the substitution of manure by chemical fertilizer contaminate the underground water and soil.More
Pre-Treatment: The mechanical and biological pre-treatment used on straws, can increase the contact area between materials and microorganisms and accelerate the process of hydrolysis and acidification of organic matter, and also make the further effects on the next step to raise the biogas production.
The mechanical and biological treatment can increase the contact area between materials and microorganisms, accelerate the process of hydrolysis and acidification of insoluble macromolecular long carbon chain in material.More
Materials inside the tank may contain up to 15% solids, nearly twice more than the traditional wet anaerobic digestion fermentation solution, thus greatly increasing the gas production rate per unit. The paddle agitator stirs materials evenly at a low speed. Biogas will be generated under the condition of medium-temperature between 38 to 42°C in the anaerobic digestion fermentation for 40 to 60 days.

Control-Loss Fertilizer: Based on the residues aerobic fermentation and nano-material, the control loss fertilizer is developed with efficient cost and environmental friendly character, which can increase the adsorption capacity of fertilizers in soil.
Revenue of the semi-dry anaerobic digestion fermentation project are mainly derived from sales of biogas upon purification or grid-connected power generation. Our ultimate goal is to realize the circular economy mode. Specifically, under the support of the government, we may effectively collect straw, livestock muck, etc. The biogas produced by anaerobic digestion fermentation can be used for purification or co-generation. Anaerobic digestion fermentation residues can be produced into solid organic manure and liquid organic fertilizer for sales.
Our ultimate goal is to realize the circular economy mode. Turn the agricultural waste into biogas by anaerobic fermentation. The fermentation residues can be produced into solid organic manure and liquid organic fertilizer for sales.More
