The bio-digesters are «biological engines» allowing the transformation of organic matter (liquid or dry) into biogas and stabilised organic fertiliser.
Bio-digesters convert organic matter carbon in methane (CH4) and carbon dioxide (CO2). The nutrients in organic matter (N, P, K) are not removed and are the by-products (sludge, treated effluent). These by-products become excellent organic fertiliser.

Composting is a technique of processing organic by-products (solid).
Depending on raw material, land available, environment, weather conditions, objectives and industry policy, BIOTEC engineers composting plants by front turner (traditional system), by side turner and/or by forced aeration.
For the effluents and wastes not to be discharged in rivers or landfills, it is necessary to find ways to return the organic matter and nutrients they contain to the soil. Agronomy and agricultural engineering are a complement to environmental and sanitary engineering. Fertilisation with fresh or decomposed organic material is already common practice in agriculture around the world. Liquid Organic Fertilisation is less well known but equally important.
When liquid application technologies do not exist or are not satisfactory for technical or financial reasons, BIOTEC engineers innovative solutions for organic fertiliser application. The principles and features largely depends on the type of crop. This is the case of "FORLIM"® (Liquid Organic Fertilisation Monitored System), that allows the application of treated effluent and sludge from the bio-digesters in a controlled fashion on the plantations. The FORLIM uses a computer system (SCADA) and a GIS (Geographical Information System) allowing online control and tracking of the fertilisation process.
The FORLIM generate periodic reports on fertilisation for the management and/or environmental authorities.
Dosage of nutrients per hectare per year are similar to the dosage used for chemical fertilisation.
|Crop||Dosage (liquid organic fertilizer).|
|OIL PALM:||100 - 300||m3/ha-year|
|SUGARCANE:||50 - 300||m3/ha-year|
|CITRUS:||1000 - 2000||m3/ha-year|
BIOTEC designs, builds, implement and supervises its solutions on an industrial scale, with its own technology and through thorough quality control both internal as well as with its suppliers.
A good installation must be correctly operated to take advantage of its full potential. BIOTEC is committed to its customers and will operate the plant for the first two years. In this way the plant will operate at the designed performance (KPI) and the customer’s operational team can be fully trained.
