BIOGAS STATIONS
AND COMPOSTING PLANTS

Biogas stations and composting plants are modern and ecological facilities which process wide variety of materials or waste of organic origin. The composter processes waste by controlled aerobic digestion. The composting itself takes place in strip piles. The quality of the process is controlled by measuring temperatures and with mature compost by chemical analysis of heavy metals, ration of C:N, physical parameters, and watercress test.

Biogas stations process waste by anaerobic digestion without access to air. Biogas generates in sealed reactors and is often used to make electricity and heat. The by-product, digestate, can be further processed as e.g. quality fertilizer.

We offer building biogas stations and composting plants for processing organic materials the so called ‘dry way’.

Construction of a biogas station

 FERMENTERS

These are sealed chambers where organic material decomposes the ‘dry way’ in order to make biogas. Fermenters are long (L= cca 30m) with diagonal profile (B/H) allowing for loading and unloading the material with a wheel loader. These requirements are met using prefabricated segments which are joined by special locks, rubber insulation, and sealing cement. The prefabricated construction is protected by utility model.

 INDUSTRIAL HALL

It is used for storage of input material and further processing of solid waste. The hall is constructed of reinforced concrete frame, which is connected to the fermenter structure. The shell of the hall is manufactured according to each project (we offer SPIROLL precast floor slabs in a sample construction).

Construction of composting plant

The composter plant consists of three separate objects:

• Sanitation hall – similar construction to the fermenter hall
• Composter – light construction to cover the space where composting takes place
• Warehouse – custom made to suit customers’ needs
