The deformation of municipal solid waste is a complex process caused by the nature of MSW, the properties of which differ from the properties of common soils. The mass of municipal solid waste shows the mixed behaviour partially similar to granular soils, and partially - to cohesive. So, one of mechanical characteristics of MSW is the cohesion typical to cohesive soils, but at the same time the filtration coefficient of MSW has an order of 1 m/day that is characteristic for granular soils. It has been established that MSW massif can be simulated like the soil reinforced by randomly oriented fibers. Today a significant amount of the verified and well proved software products are available for numerical modelling of soils. The majority of them use finite element method (FEM). The soft soil creep model (SSC-model) seems to be the most suitable for modelling of municipal solid waste, as it allows estimating the development of settlements in time with separation of primary and secondary consolidation. Unlike the soft soil, one of the factors of secondary consolidation of MSW is biological degradation, the influence of which is possible to consider at the definition of the modified parameters essential for soft soil model. Application of soft soil creep model allows carrying out the calculation of stress-strain state of waste from the beginning of landfill filling up to any moment of time both during the period of operation and in postclosure period. The comparative calculation presented in the paper is executed in Plaxis software using the soft-soil creep model in contrast to the calculation using the composite model of MSW. All the characteristics for SSC-model were derived from the composite model. The comparative results demonstrate the advantage of SSC-model for prediction of the development of MSW stress-strain state. As far as after the completion of the biodegradation processes MSW behaviour is similar to cohesion-like soils, the demonstrated approach seems to be useful for the design of waste piles as the basement for different constructions considering it as one of remediation techniques for the territories occupied by the old waste.

Though the technologies of waste recycling and disposal are continuously developing, waste storage on dumps and landfills still remains one of the most popular storage methods. There are twice more illegal dumps than legal ones. Waste dumps have negative effect on the environment and attract insects, rodents and stray animals. The analysis of data on beginning of operation of municipal solid waste disposals showed that the majority of them are on the stage biogas emission and filtrate formation. The paper presents a method for environmental risk assessment for old dumps and landfills. The assessment method is based on point scoring according to a group of criteria and takes into account the objects’ sites, geological and hydrological conditions, technical facilities. The method allows ranking dumps’ sites basing on the priority for dump closing and it can be used for the development of regional programs for closing old dumps and operating municipal landfills.

Municipal solid waste (MSW) is a significant environmental and sanitarian problem for urban areas. Different, often alternative, measures are considered in order to reduce the environmental impact of MSW management system, so adequate technique of comparative assessment of their environmental efficiency is needed. The problem is that waste composition, dangerous and organic matter content are often ignored when environmental impacts of MSW management system are calculated. Therefore, an algorithm of environmental impact estimation of municipal solid waste treatment based on their composition and properties is a question of considerable importance.The main difficulty in performing environmental impact calculation in compliance with MSW composition is the evaluation of the emissions per waste unit. Waste component content and biodegradable carbon content in every component are taken into account as basic waste features for emission estimation. Methane generation potential is calculated as a function of biodegradable carbon content.Environmental impacts of waste treatment on manual sorting plant in Yekaterinburg are given as an example. Waste composition analysis was carried out there in 2012. Material flow analysis allowed clarifying mass balance of the process. About 10 % of income waste mass are going out of the waste management system as a recyclables and determine the decreasing of environmental impacts. 1.24 % of biodegradable carbon don’t reach landfills, so it means that production of about ten cubic meters of biogas per ton of income MSW are prevented. When converting this data in money, it results in 47.1 rubles per ton of MSW or about 4.7 million rubles annually.

Introduction. The approach to the creation and development of the system of separate collection and pre-treatment of municipal solid waste (MSW) and bulky waste. At present, Russia is lagging behind in the level of waste disposal, the expedient use of secondary resources. One of the main reasons is the lack of a cost-effective system for managing waste and secondary resources. Despite the deteriorating environmental situation, the closure of landfills for municipal solid waste, the growth of unauthorized landfills, there has been a trend of growth in tariffs for removal and disposal of municipal solid waste (MSW) and bulky waste affecting the entire population of Russia. This problem determines the need to find new scientific and methodological approaches and practical solutions for planning not only the placement of industrial waste disposal infrastructure, but also creating a system for separate collection and pretreatment of MSW and bulky waste in the sources of their formation, justification and optimization of the standards for the accumulation of this waste for citizens. Materials and methods. Materials for conducting a scientific research are: legal acts, standards, guidelines and recommendations, regulatory and technical documentation in the field of waste management, published materials of domestic and foreign scientific research. The methods of scientific research are based on the use of factor, comparative, expert types of analysis. Results. Optimization of the system for calculating the standard of accumulation of MSW and bulky waste is proposed; reducing the financial burden on citizens in terms of tariffs for garbage collection; economic incentives for the population to separate the collection of MSW with the pretreatment of the components of this waste to the level of demanded secondary resources. Conclusions. The introduction of the proposed system will allow achieving socio-economic, environmental, natural resource, political effect, consolidating the society to solve the problem of resource conservation, the use of secondary resources.
