Biological waste is a special type of unsuitable material, the collection, storage, transportation and disposal of which is regulated by laws.
Compliance with these standards is mandatory for all animal owners, veterinary organizations, livestock farms and other enterprises engaged in the production or processing of animal products.
Biological waste regulated under these rules include:
— corpses of animals and birds, including laboratory;
— aborted and stillborn fruits of birds and animals;
— confiscated items;
— secondary waste processing of raw materials of animal origin.
Since biological material is potentially dangerous for the environmental and sanitary-epidemiological situation, its disposal by burial in the ground is strictly prohibited. It is also prohibited to throw biomass into garbage containers or take it to landfills for further disposal.
Meanwhile, biological and veterinary waste is a very large part of all produced garbage.

And if the disposal of biological waste in landfills is unacceptable, what method is allowed and from the point of view of the law and environmental safety?
To date, the most effective method of disposal of hazardous waste is incineration. The use of special equipment – incinerators– allows to neutralize large amounts of unsuitable materials in compliance with all sanitary and epidemiological requirements.
And it is worth noting that with such a high level of concentration of hazardous substances, the market for their disposal has virtually no competition. Therefore, the use of incinerators at animal waste disposal facilities is also due to a number of economic benefits.
Let’s look at the average market cost of services for cremation and disposal of animal waste for individuals.
The company rendering services in utilization of biological waste carries out and transportation of unsuitable material directly to the place of its subsequent destruction.
Average market value of waste disposal services for organizations and enterprises

The main consumers of the facility for the disposal of biological waste, however, are livestock enterprises and production. Although many of them already use incinerators on their own premises, the demand for this service exceeds the supply.
How to optimize the cost of disposal of biological waste in an incinerator?

One of the most rational solutions to optimize the recycling process is the additional equipment with a heat recovery system. Thanks to this solution, the energy generated by the incinerator will be used to produce heat to heat the room or water.
Installation of such a heat recovery system is carried out at the stage of development and production of the incinerator in accordance with its technical characteristics and features of subsequent operation.

But what about the issue of environmental security?

The problem of proper disposal of waste, including biological, is particularly relevant for countries. There is no doubt that incineration is an effective and cost – effective method of waste disposal, but how safe is it for the environment?
Modern incinerators are equipped with additional equipment-the afterburning chamber of combustion products (gases formed in the process of burning garbage) and a gas cleaning system that prevents the ingress of hazardous exhaust into the atmosphere.
All this makes it possible to guarantee the absolute safety of the recycling process for the environment and for the environment as a whole

Waste of oil products — what is it
Oil is a mixture of hydrocarbons, sulfur-and oxygen-containing compounds. Roughly speaking, waste from oil production and refining is the difference between the oil produced and the products derived from it. According to scientific terminology, oil-containing waste, or oil sludge – is a multicomponent mixture, which contains petroleum products, clay, various metal oxides, sand and water. The listed components in fractions of a unit are in the ratio:

substances of organic origin: 0,1-0,25;
substances of inorganic origin: 0.05 -0.3;
water: 0.5-0.7.
Oily waste is generated at all stages of production, transportation, processing, storage and use of oil and products derived from it:

during production, oil is spilled onto the ground and mixed with soil or soil;

during transportation by sea, accidents and accidental ingress of oil products into the water are possible (oil waste is included in the water-oil emulsion). During transportation by land or through pipes, accidental ingress of oil and its products to the soil surface is also possible (a mixture of petroleum products and soil is formed);
at refineries, wastewater containing oil waste is collected for sedimentation in special ponds and oil traps. After settling, the surface of the pond contains up to 80% of oil sludge, muddy bottom — up to 1%, the middle part — up to 90%. After cleaning the tanks where oil or oil products were stored, a mixture of oil sludge with mechanical impurities, such as rust, is formed;
when used and stored, spills of oil and petroleum products are possible (a mixture of petroleum products and soil is formed).
Oily waste can be divided into:

Liquid waste containing a lot of water and easily separated from it.
Gel-like waste obtained by chemical treatment of wastewater. Separation of waste from water is difficult.
Waste containing little combustible products and is not practically separable from water.
Waste with a high concentration of petroleum products, requiring special methods of disposal.
Mankind uses the following methods of disposal of oily waste:

Placement in sealed containers and burial in special landfills. The method is not environmentally appropriate due to the risk of leaks and accidents. Its use can lead to environmental disasters. In addition, it is economically much more profitable to use oil waste for the second time.

Disinfection and recycling. This method includes methods:

The thermal method involves incineration of oil refining waste in furnaces, drying, pyrolysis and thermal desorption. More is the combustion in the bubbling chamber, a shaft, rotary kilns and fluidized bed.

This method of disposal can be called more effective along with other possible methods. Thermal utilization of oil waste and fire neutralization of contaminated water in the presence of a fuel-burning plant is economically feasible and environmentally beneficial to carry out in places of their formation.
