The compost bin is used to convert the solid food waste into useful organic compost.


Pyrolysis is a thermochemical treatment, which can be applied to any organic (carbon-based) product. It can be done on pure products as well as mixtures. In this treatment, material is exposed to high temperature, and in the absence of oxygen goes through chemical and physical separation into different molecules

How It Works?!

During the pyrolysis, a particle of material is heated up from the ambient to defined temperature The material remains inside the pyrolysis unit and is transported by screw conveyor at defined speed, until the completion of the process. Chosen temperature of pyrolysis defines the composition and yields of products (pyrolysis oil, syngas and char).

Factors Affecting Pyrolysis Process

Treated material composition – each of the major constituents of biomass and waste feature different temperatures of thermal decomposition, which means they contribute to the results of process in different way. Due to high diversity of material compositions it is always recommended to perform a pilot tests to forecast the pyrolysis process performance in most accurate way.

Temperature of process – has a major influence to the treatment results. Higher temperatures of pyrolysis provide greater quantity of non-condensable gases (syngas, synthetic gas), while lower temperatures favour the production of high quality solid product (charcoal, bio-coal, torrefied fuels). Temperature is a factor fully controllable in process thanks to electrically heated screw conveyor that allows precise setup of treatment conditions.

Residence time of material in the pyrolysis chamber – influences the degree of thermal conversion of received solid product as well as the residence time of the vapour, which influences the composition of vapours (condensable / non-condensable phase). Residence time can be precisely controlled in process by changing the rotation speed of screw conveyor transporting material along the reactor.

Particle size and physical structure – influences the speed in which material is subjected to pyrolysis. In general, lower particle size materials are quicker affected by the thermal decomposition, which can result in greater quantities of pyrolysis oil than in case of larger particle size.
