Abstract
The article presents the results of research (2013-2017) on the seasonal morphological composition of Municipal Solid Waste and forecasting the waste generation volume for Saint Petersburg. The authors propose ways to improve the system of solid waste management in St. Petersburg based on these researches.
Highlights
The annual generation of Municipal Solid Waste (MSW) in the Russian Federation is estimated about 120 million m3; 12.5 million m3 of which are accounted for Northwestern Federal District, 6 million m3 being accounted for Saint Petersburg only [1, 2]
Conducted studies were aimed at clarifying MSW generation volume and its morphological composition in order to develop practical recommendations to improve the existing waste management system
Model calculations have shown that MSW volumes in Saint Petersburg will have grown up to 12.1 million m3 (1838 thousand tons) by 2017 and 13.4 million m3 (2037 thousand tons) by 2020
Summary
The annual generation of Municipal Solid Waste (MSW) in the Russian Federation is estimated about 120 million m3; 12.5 million m3 of which are accounted for Northwestern Federal District, 6 million m3 being accounted for Saint Petersburg only [1, 2]. Methods and techniques of MSW collection and disposal being; applied result in the formation of MSW flows with significant diversity in the primary content Another important factor affecting the morphological composition of MSW, which is delivered to disposal and processing facilities, is a varied degree of prior secondary raw materials extraction from MSW. In order to unify the methodology and common approaches the following guidelines have been developed: «Methodology for Determination of the Composition of Unprocessed Municipal Solid Waste and Waste Composition Dependence from Regional Social-Economic and Climate Characteristics» This methodology is based on standard methods listed below: Standard Test Methods for MSW Determination (LST CEN/ISO 14780 «Solid biofuels Method for sample preparation»; ASTM D 5231 – 92 «Standard Test Method for Determination of the Composition of Unprocessed MSW»; ASTM D 4687 – 95 «Standard Guide for General Planning of Waste Sampling»). The main requirement in the study of MSW composition was the provision of the primary sample representativeness, since the composition of the analytical sample must strictly comply with the average composition of the full volume of the investigated waste
