Biodegradation is a special example in which polymers are broken down by biological agents. Biodegradation by microorganisms, rodents and insects is known. When protein-containing substances decompose, putrefaction occurs. The organisms involved in biodegradation are called decomposers.
At the Žirany plant, a subsidiary of Waste transport, the biotechnological disposal and recovery of hazardous waste (contaminated with oil) is carried out on an open production area of 3018 m2 by applying a preparation to the pre-treated contaminated material (waste) and maintaining conditions favorable for the development of the microbial population:
- pH 4.5 to 7.5
- temperature 5 to 35°C (but can operate in the range 0-60°C)
- humidity 40 – 60%
- air access
- nutrient supply
The formulation is developed for degradation of petroleum hydrocarbon pollution. Effectiveness has also been verified for PAH and BTEX pollution.
