Slaughterhouse waste: This includes wastes such as blood, digestive tract products, hair/skin, fat, washing water, as well as animals which according to the Hellenic Ministry of Rural Development and Food are considered unfit for human consumption. Even if slaughterhouses have some type of waste water treatment plant then sludge is also produced for management.

Poultry slaughterhouse waste: This includes wastes such as blood, feathers, poultry limbs (heads, feet), bones and offal, fat, bedding resulting from the cleaning of the waiting stable of animals, washing water and unfit birds for human consumption. If the slaughterhouses have waste water treatment plant then the resulting sludge is included in the waste.

Waste of meat standardization and processing: Include waste, such as altered production pastes, cutting residues, bones and fats and the return of products unfit for human consumption. Finally, sludge is also produced from the company’s waste water treatment plant if it is available.

Fruit and vegetable processing industries
BIOLGET cooperates with canning and fruit and vegetable processing industries, to collect, transport and manage their waste. Such as, unfit fruit, its cocoons and peel, pulp, spores, sarcoma and kernels derived from the production process of these industries. Furthermore, sludge derived from the operation of their waste water treatment plant is waste that BIOLGET has the means and capacity to use it.

Edible oils industry
BIOLGET cooperates with oil production companies to collect, transport and manage their waste.
The operation of the olive mills results in significant amounts of waste water and solid residues. In particular, the vegetable fluids of the olive fruit, the water added to its various processing stages, insoluble organic fragments in the form of suspension, cooling and washing water and emulsified droplets of oil make up the liquid waste from the oil mills. The solid waste from the mills results from the olive cleaning phase and includes leaves and small branches. Finally, if the company has waste water treatment plant, then sludge is produced for management.

Starch and starch-products industries
This includes industries active in the production of starch and gluten resulting from the processing of maize as well as potato chips and pasta industries.
Wastes from these industries are divided into liquid and solid waste. Solid waste is considered as the refunds of products unfit for consumption, waste resulting from production (usually in bulk form), defective/unfit raw materials for further processing, residues resulting from peeling and cutting of raw materials, solids captured in cyclone or bag filters, powders etc. These industries also produce liquid waste, which are usually small hydraulic load resulting from washing water processes, liquids resulting from extraction of the starch feedstock and biological sludges of the industry if available.

Sugar production is a complex process with many process stages. In this process (beet reception/washing and cutting, extraction, pre-liming/liming, saturation, filtration, condensation, crystallisation and centrifugation) are produced beyond crystallized sugar and various wastes.

In particular, liquid wastes produced from the cleaning process of the production and solid wastes such as beet-cleaning sludges, sludge from the waste water treatment plant (if available) and lime-sludge produced from the addition of calcium milk to clean the raw beet juice. Furthermore during production there are waste from the slicing of beet but also semi-solid residues (fresh pulp) collected by screening after the pulp extraction process. Finally, the sugar crystallisation process produces a dark and viscous liquid that remains as a residue (molasses) rich in organic matter.

In this area we are responsible for collecting, transporting and managing short-term and unfit packaged products, waste water resulting from the production process of the industries – crafts and sludges (European Waste Catalogue -EWC- codes) of the waste water treatment Plant in liquid or solid form.

The transport of packaged animal by products of category 3 (ABP 3) is always carried out with refrigerated trucks approved by the Hellenic Ministry of Rural Development and Food in order to maintain the cold chain during transport and to avoid further deterioration. While liquid waste resulting from the production process (cheese milk, yoghurt serum, etc.) is transported by tank truck.

BIOLGET is responsible for collecting, transporting and managing short and unfit packaged products (dough, flour, etc.) and waste resulting from the production process of the craft industries in bulk form (losses from dough, products in inappropriate form, etc.).

The amount of liquid waste in the Greek paper industry depends on water consumption either as washing water or for production. These wastes are burdened with energy (usually heat), by-products of the production process as there are suspended solids, dissolved substances and colloidal dispersions within them. More specifically, there are compounds used in the production process and substances resulting from the decomposition of the original compounds.
The use of kaolin, cellulose and other chemical compounds in the production process is an inhibitory factor in the treatment of waste as the abovementioned compounds prevent appropriate nitrogen, phosphorus and carbon ratios for biological degradation.
Solid waste consists of: (a) solid resulting from the processes of separating impurities, (b) from raw materials, (c) sludges from biological purification facilities.

BIOLGET, by participating in public procurement procedures, undertakes waste collection, transportation and environmental management operations from public water supply and sewerage Companies (D.E.Y.A). In particular, we are carrying out projects for the collection, transportation and management of solid waste from D.E.Y.A., sludge waste and other solid waste resulting from the different waste water treatment stages (screening etc.) of biological purification system.
