Current Activities

Landfill

Municipal wastes arriving at Biotrend Integrated Waste Management facilities are processed by directing them to the relevant units according to waste types. Accordingly, municipal wastes are directed to mechanical separation and material recovery facilities, park garden wastes are directed to composting facilities, wastes suitable for biofuel production after mechanical separation are directed to anaerobic fermentation units, and wastes suitable for energy recovery are directed to ATY facilities. Industrial wastes that can be accepted to landfills in accordance with the legislation and wastes that are not suitable for material and energy recovery after mechanical separation are directed to landfills and disposed of.

Biogas

Biogas production starts with the transfer of organic wastes separated by processing municipal wastes in Biotrend mechanical separation and material recovery facilities to anaerobic fermentation units via conveyors. In a process of approximately 28 days, organic wastes are mixed horizontally in a thermophilic environment and biogas production is completed. The biogas produced at the end of the process is stored in a biogas balloon. Before energy production, the biogas is directed to the gas conditioning unit to remove moisture, hydrogen sulfide and solid particles. Gas engines generate electricity and heat from the biogas. While the generated bioelectricity is offered to the grid, the bioheat is utilized in the biogas production process of the anaerobic fermentation units, ensuring energy efficiency in the facility.
Biotrend produces biogas with a total of 10 anaerobic fermentation units in Bergama, Malatya, Uşak and İnegöl Integrated Waste Management facilities.

Landfill Gas

After the acceptance of municipal wastes to the landfill within the scope of landfill activities, landfill gas rich in methane gas is formed over time through anaerobic fermentation process. In order to provide environmental and economic benefits by using landfill gas, which contains greenhouse gases harmful for environmental pollution and climate change, in energy production, landfill gas is collected effectively and efficiently in the landfill and used in energy production after the gas conditioning process.

Waste Derived Fuel (WDF)

In order to meet the solid fuel need of Biyomek Biomass Power Plant, ATY, which is formulated in technical compliance with the power generation process of the plant, is produced from agricultural and forestry wastes at the Ulubey Solid Fuel Preparation Plant. Ulubey Solid Fuel Preparation Plant accepts agricultural wastes generated as a result of wheat, barley, corn, sunflower, cotton and sugar beet production. Thus, farmers are supported by ensuring that agricultural wastes are transformed into economic value, while human and nature-friendly energy production is realized in the biomass power plant from domestic-renewable resources.

Compost Production

With its compost production activities, Biotrend aims to reuse the compost obtained from municipalities' park and garden wastes in landscaping and landscaping applications. Accordingly, the compost production process includes the physical sizing and blending of park and garden waste collected by municipalities, followed by processing according to the raw material type to obtain compost end product. Investments in Harmandalı, Bergama and Balıkesir plants are expected to start in 2024.

Mechanical Separation and Material Recovery

Mechanical separation and material recovery activities include mechanical pre-treatment of municipal waste to make it suitable for fuel production and material recovery. Municipal waste is processed in sorting cabinets with plastic and magnetic separators and metals are recovered to obtain circular feedstock, the organic part is directed to biofuel production and the part suitable for energy recovery is directed to Waste Derived Fuel (WDF) production as feedstock. Circular feedstocks are supplied for processing in the production of recycled plastics and metals, while biocircular feedstocks are shipped to biogas and landfill gas production.

Biotrend processes an average of 6 thousand tons of waste per day through mechanical separation and material recovery activities carried out at 8 Integrated Waste Management Facilities.
