One of the most important tasks in St. Petersburg and the Leningrad region is the problem of waste collection and disposal.

Current legislation of the Russian Federation, regulatory documentation federal level determine the legal basis for the management of production and consumption waste and establish responsibilities for all individuals and legal entities in matters of environmental management, compliance sanitary standards and rules.

Federal Law “On Production and Consumption Waste”; “Temporary rules for environmental protection from production and consumption waste” apply to enterprises, associations, organizations, institutions, regardless of their form of ownership and departmental subordination, individuals, as well as foreign legal entities (hereinafter referred to as users of natural resources) carrying out any type of activity on the territory of the Russian Federation, as a result of which production and consumption waste, with the exception of radioactive waste, is generated, used, neutralized, stored and buried.

According to the Federal Law “On Production and Consumption Waste”, individual entrepreneurs and legal entities When operating enterprises, buildings, structures, structures and other objects related to waste management, you are obliged to:

Comply with environmental, sanitary and other requirements established by the legislation of the Russian Federation in the field of environmental protection and human health;


Develop draft standards for waste generation and limits on waste disposal in order to reduce the amount of waste generation.

The projects being developed contain information that is the basis for establishing standards for waste generation and limits on their disposal, which must be established for each use of natural resources in accordance with the new Federal Law “On Environmental Protection” (Article 24). The resulting standards serve as the basis for payment for negative impact on the environment, which must be carried out in accordance with Art. 16 of the Federal Law “On Environmental Protection”.

Enterprises are obliged to promptly remove generated waste, since long-term storage of waste on their territory leads to deterioration of land quality and pollution of natural environments.

These requirements are declared in the new Federal Law “On Environmental Protection”, according to which production and consumption wastes are subject to collection, use, neutralization, transportation, storage and burial, the conditions and methods of which must be safe for the environment (Article 51). In accordance with the same article of the law, prohibitive conditions for waste management are defined.

At motor transport enterprises, as well as enterprises that have a significant number of vehicles on their balance sheet and independently carry out maintenance and repair of vehicles, the problem of waste management is especially relevant, since in the process of their work more than 15 types of production waste are generated, including II and III hazard class.


Production waste at the enterprises under consideration is generated during the repair and maintenance of vehicles. As a rule, enterprises carry out work on repairing engines, troubleshooting vehicle components, manufacturing and repairing parts and components of vehicles. Inspection and diagnostic, fastening, adjustment and other work is carried out, as well as oil changes in automobile oil systems.

Appendix 1 provides a list of production waste generated at a motor transport enterprise. Let us dwell in more detail on the analysis of the waste listed in the appendix.

When repairing and maintaining vehicles, individual parts and components of vehicles that have expired are replaced. At the same time, ferrous metal scrap (used metal car parts), industrial waste (used non-metal car parts), filters contaminated with petroleum products (fuel and oil filters), cardboard filter (air filters), used brake pad linings, tires with metal cord, tires with fabric cord.

Used batteries can be recycled either assembled or disassembled. Depending on this, the enterprise may generate different types of waste. If used batteries are disassembled, the following types of waste are generated: scrap non-ferrous metals (depending on the type of battery), polymer waste (plastic battery case), spent battery electrolyte after its neutralization or sediment from neutralization of the electrolyte. If the electrolyte is not neutralized at the enterprise, used batteries are generated as waste.

When replacing used oils, the following types of waste are generated: used motor oil, used transmission oil. When changing oil in hydraulic systems of excavators, waste hydraulic oil is generated.


To clean up oil spills in garages, sawdust and sand can be used, resulting in sawdust contaminated with petroleum products or soil containing petroleum products as waste.

During vehicle maintenance, rags are used to wipe oily surfaces. The oily rags resulting from this are sent to waste.

Car washes are carried out at individual transport enterprises. At the same time, treatment of contaminated wastewater after washing vehicles must be organized. One of the requirements for organizing vehicle washing is their transfer to treatment facilities. As a rule, treatment facilities for car washes are a sump with an oil trap or filters. Here the separation and sedimentation of suspended substances and purification from petroleum products take place. Suspended substances settling to the bottom of wells (vehicle wash residues) and floating oil products from oil traps are regularly removed, forming waste. Filters contaminated with petroleum products must be replaced and also go to waste.

In addition to the above production waste, at motor transport enterprises, as well as at others, consumer waste is generated - household waste, waste tubular fluorescent lamps, waste mercury lamps for outdoor lighting (in the case of using mercury lamps to illuminate the territory and premises of the enterprise), waste from the territory, sewage waste that does not contain toxic metals.

The generation of industrial waste is calculated based on the standard service life of the corresponding vehicle parts adopted in the automotive industry.


Calculation of used batteries is made based on the number of batteries of each type installed on vehicles, the weight of the batteries together with the electrolyte, and the operating life of the batteries. The summation is made for all brands of batteries. The operating life of batteries and the weight of batteries by brand are indicated in reference books. An example of calculating used batteries is given in Appendix 2.

If the spent electrolyte is drained from the batteries, the weight of the battery is taken without electrolyte, and the calculation of the spent electrolyte of the batteries is carried out separately using reference data given in the reference literature. Examples of calculations of used battery electrolyte and used battery electrolyte after its neutralization are given in Appendix 3.

The calculation of used oil, fuel and air filters is made based on the number of vehicles on the enterprise's balance sheet, the number of filters installed on each vehicle, the weight of the filters, the average annual mileage of vehicles and the mileage rate of each brand of rolling stock before replacing filter elements. The standard mileage of rolling stock before replacing filters is taken from reference data. An example of calculating spent filters is given in Appendix 4.

Calculation of the amount of ferrous metal scrap generated during the repair of motor vehicles is made based on the average annual mileage of each vehicle, the standard mileage of rolling stock before repair, and the specific standard for the replacement of ferrous metal parts during repair. The rolling stock mileage rate before repair is indicated in the reference literature. The specific replacement standard for parts made of ferrous metals is usually 1 - 10% and is determined based on inventory data.

The standard quantity of used brake pads is determined based on the number of cars, the number of brake pads installed on one car, the weight of one pad, the average annual mileage of cars of each brand, the standard mileage of rolling stock before replacing the brake pads, which is determined from reference data. An example of calculating used brake pads is given in Appendix 5.


Calculation of the standard quantity of used car tires - tires with fabric cord and tires with metal cord is made based on the number of cars on the balance sheet of the enterprise, the number of tires installed on a car of each brand, the weight of one worn tire of each brand, the average annual mileage of a car of each brand, the mileage rate rolling stock of each brand before tire replacement. Recommended types of tires for vehicles of various brands, as well as the number of tires installed on vehicles of various brands and the weight of the tires are given in the reference literature, or in the technical documentation attached to the supplied tires. An example of calculating used tires is given in Appendix 6.

Calculation of used engine oil and used transmission oil can be done in two ways. In the first case, the calculation is made through fuel consumption. The initial data for the calculation are the fuel consumption rate per 100 km, average annual vehicle mileage, oil consumption rate per 100 liters of fuel, waste oil product collection rate. The fuel consumption rate and oil consumption rate by car brand are determined from reference data or from technical documentation for vehicles. The collection rate for waste petroleum products is, according to 0.9. The calculation is made separately for each type of oil. An example of calculating used oils is given in Appendix 7.

When calculating used engine and transmission oil through the volume of the lubrication system, the initial data for the calculation are the volume of oil poured into cars of each brand during maintenance (determined by ), the average annual mileage of each car, and the mileage of rolling stock before an oil change.

The amount of sludge from vehicle wash treatment facilities and floating oil products from oil traps (in the absence of reagent treatment) is calculated based on the annual wastewater flow rate, the concentration of suspended solids and oil products before the treatment facility, the concentration of suspended solids after the treatment facility, and sludge moisture. When using reagents for purification, it is necessary to take into account the amount of sediment formed from the amount of reagents used.

The annual wastewater consumption is determined taking into account the standard water consumption for washing one car and the number of car washes per year. The standard water consumption for washing one car is indicated in the reference literature.


Concentrations of suspended solids and petroleum products before and after treatment facilities are indicated in the technical documentation for treatment facilities or are determined based on the results of wastewater control analyses.

In the absence of technical documentation for treatment facilities, vehicle washing and the results of wastewater control analyses, the concentration of petroleum products and suspended solids in wastewater for motor transport enterprises is accepted in accordance with reference regulatory data. An example of calculating sludge from treatment facilities, vehicle washes and floating oil products from oil traps is given in Appendix 8.

If the vehicle wash treatment facilities contain filters for removing petroleum products, then when they are replaced, filters contaminated with petroleum products are formed as waste. Their calculation is made based on the weight of the used filter, their quantity and the frequency of replacement according to the passport data for the treatment plant.

Calculation of oiled rags is made based on the amount of dry rags consumed during the repair and operation of vehicles and the content of petroleum products in oiled rags. An example of the calculation is given in Appendix 9.

For a whole range of waste (industrial waste, sawdust contaminated with petroleum products, soil containing petroleum products), the standard amount of waste is determined based on the average actual data of the enterprise for the last 2 years.


Temporary storage of waste generated during the repair and operation of vehicles must be carried out in specially designated places equipped for this purpose. When storing waste, its impact on the soil, surface and ground water, and atmospheric air must be excluded.

Most of the waste generated at motor transport enterprises is subject to disposal at specialized waste processing enterprises (tires with metal cord and fabric cord, soil containing petroleum products, waste oils, floating oil products from oil traps, sludge from treatment facilities of vehicle washes, used batteries, waste battery electrolyte , as well as waste fluorescent lamps).

Spent fluorescent and mercury lamps are disposed of at the following enterprises: Electricity supply service of the St. Petersburg metro, NPO Eneko, located on the territory of the pilot plant of the Russian Research Center Applied Chemistry, Skat LLC and NEP CJSC, renting a facility for demercurization of mercury lamps from the Radium Institute them. Khlopin, MEP "Mercury".

Regeneration of used oils is carried out at the Russian Research Center "Applied Chemistry", VNII "Transmash" and LLC "PTK-TERMINAL".

Soil and water purification from petroleum products is carried out using the biotechnological method of ZAO Ecoprom and ZAO Orlan-Eko.

Waste electrolytes, waste and other waters are disposed of by extracting heavy metal cations from them at JSC NTO "ERG" and the Rossiya enterprise.

Used batteries and other lead-containing waste are accepted for recycling by AOZT ENPC "MKT" and AOZT NPO "Kathod".

Waste tires are accepted for recycling by MPBO Pilot Plant CJSC, MPBO-2 State Unitary Enterprise, Yugo-Zapadnoe State Industrial Plant, Petrogradskoe PZP LLC, and Elast CJSC.

Waste from the operation of motor vehicles that cannot be recycled (oily rags, industrial waste, used brake pad linings, filters contaminated with petroleum products, cardboard filters) is transported to MPBO plants for the purpose of their disposal, taking into account compliance with environmental protection requirements.

Used batteries (215.01)
(calculation example)

Calculation of the standard generation of used batteries is carried out based on the number of installed batteries (according to the enterprise), their service life and the weight of the battery. The calculation was carried out according to the formula:

N = aN auto.i ? n i /T i , pcs./year,

where - N cars i - number of cars equipped with batteries of the i-th type;

n i - number of batteries in the car, pcs.;

T i is the operational service life of batteries of the i-th brand, year.

The weight of the resulting waste batteries is:

M = aN i ? m i ? 10 -3 , (t/year),

m i is the weight of the i-type battery without electrolyte.

The initial data and calculation results are presented in Table 2.1.

Table 2.1

The total standard quantity of used batteries at the enterprise is 0.071 t/year.

Literature:

Waste battery electrolytes (043.01)

M = aN i? m i, l,

where: N i - number of used batteries of the i-th brand, pcs./year;

The initial data and calculation results are presented in Table 3.1.

Table 3.1

Taking into account the density of the spent electrolyte, which is 1.27 kg? l, the amount of spent electrolyte will be 19 kg or 0.02 t.

Spent battery electrolyte after its neutralization (043.04)
(calculation example)

The spent electrolyte is calculated using the formula:

M = aN i? m i, l,

where: N i - number of used batteries of the i-th brand, pcs./year;

m i - weight of electrolyte in the battery i-th brand, l.

The initial data and calculation results are presented in Table 3.2.

Table 3.2.

Taking into account the density of the spent electrolyte, which is 1.27 kg? l, the amount of spent electrolyte will be 86.6 kg or 0.087 t.

The amount of sediment formed during electrolyte neutralization is determined by the formula:

M os.el. = M + M ex. + M water,

where M is the amount of precipitate formed in accordance with the reaction equation;

M pr. - the amount of lime impurities that have passed into sediment;

Neutralization of the electrolyte with quicklime takes place according to the following equation:

H 2 SO 4 + CaO + H 2 O = CaSO 4? 2H 2 O.

the amount of CaSO 4 precipitate formed? 2H 2 O in accordance with the reaction equation is equal to:

M = 172? Uh? С/98, t/year,

where: M e - amount of spent electrolyte, t;

C is the mass fraction of sulfuric acid in the electrolyte, C = 0.35;

172 - molecular weight of calcium sulfate crystalline hydrate;

98 - molecular weight of sulfuric acid

M = 172? 0.087? 0.35/98 = 0.053.

The amount of lime (M from) required to neutralize the electrolyte is calculated by the formula:

M from = (56? M e? S)/(98? P),

where: 56 is the molecular weight of calcium oxide;

P - mass fraction of the active part in lime, P = 0.6

M from = (56 ? 0.087 ? 0.35)/(98 ? 0.6) = 0.029.

The amount of lime impurities (M pr.) that has passed into sediment is:

M pr. = M from. (1 - P)

M pr. = 0.029(1 - 0.6) = 0.011 t

M water = M e? (1 - S) - Uh? WITH? 18/98 = Uh? (1 - 1.18C)

M water = 0.087? (1 - 1.18 ? 0.35) = 0.051 t

The amount of wet sediment formed, taking into account impurities in lime, is equal to:

M os.vl. = M + M pr. + M water = 0.053 + 0.011 + 0.051 = 0.115

Thus, the standard amount of spent electrolyte after its neutralization will be 0.113 t/year.

(calculation example)

The number of washes is: for trucks - 200 washes/year, for cars - 250 washes per year, for buses - 90 washes/year.

The amount of sludge pulp (cake) W retained in the settling tank is calculated according to the formula:

W = w? (C 1 - C 2) ? 10 6 /(100 - V) ? g, m 3,

where: w - volume of wastewater from washing vehicles, m 3 ;

w = q? n? 10 -3 ? 0.9, m 3,

is 200 l for cars, 800 l for trucks, 350 l for buses;

n is the average number of washes per year.

Water losses during car washing are 10%.

For passenger cars:

w = 200 ? 0.9? 250? 10 -3 = 45.0 m 3

For trucks:

w = 800 ? 0.9? 200? 10 -3 = 144 m 3

For buses:

w = 350 ? 0.9? 90? 10 -3 = 28.35 m 3

C 1 and C 2 are the concentrations of substances, respectively, before and after purification.

For trucks, the content of suspended solids before the settling tank is 2000 mg/l, after the settling tank - 70 mg/l, the content of petroleum products is 900 mg/l and 20 mg/l, respectively.

For buses, the content of suspended solids before the settling tank is 1600 mg/l, after the settling tank - 40 mg/l, the content of petroleum products is 850 mg/l and 115 mg/l, respectively.

B - sediment humidity is 85%;

g - volumetric mass of sludge pulp is 1.1 tons.

Waste quantity:

for passenger cars

G c bb = 45? (700 - 40) ? 10 -3 ? 1.1 = 33 kg/year

G c np = 45 ? (75 - 15) ? 10 -3 ? 1.1 = 3 kg/year

G c bb = G c /(1 - ?) = 33/(1 - 0.85) = 220 kg/year

G c np = G c /(1 - ?) = 3/(1 - 0.50) = 6 kg/year

For trucks:

G c bb = 144 ? (2000 - 70) ? 10 -3 ? 1.1 = 306 kg/year

G c np = 144 ? (900 - 20) ? 10 -3 ? 1.1 = 139 kg/year

Taking into account the moisture content of the sediment? = 0.85 its real quantity will be equal to:

G c in = G c /(1 - ?) = 306/(1 - 0.85) = 2040 kg/year

G c np = G c /(1 - ?) = 139/(1 - 0.50) = 278 kg/year

For buses:

G c bb = 28.35? (1600 - 40) ? 10 -3 ? 1.1 = 49 kg/year

G c np = 28.35 ? (850 - 15) ? 10 -3 ? 1.1 = 26 kg/year

Taking into account the moisture content of the sediment? = 0.85 its real quantity will be equal to:

G c bb = G c /(1 - ?) = 49/(1 - 0.85) = 327 kg/year

G c np = G c /(1 - ?) = 26/(1 - 0.50) = 52 kg/year

The total amount of sediment from the vehicle wash treatment facilities is:

220 + 2040 + 327 = 2587 kg/year = 2.587 t/year.

Total amount of floating oil products from oil traps:

6 + 278 + 52 = 336 kg/year = 0.336 t/year.

Thus, the amount of sediment from the treatment facilities is 2.587 t/year, the amount of floating oil products from oil traps is 0.336 t/year (including humidity).
