Carbon footprint of the Novosibirsk region Waste sector

Abstract

To achieve carbon neutrality in Russia by 2060, it is necessary to regulate the volume of greenhouse gases at the regional level. Among all regions of Russia, the balance of greenhouse gases by sectors of the economy is calculated only for the Sakhalin region. The study of this article aims to assess the level of greenhouse gas emissions from the Waste sector in Novosibirsk region, taking into account territorial and sectoral characteristics. During the study, the authors used the methodology of the Intergovernmental Panel on Climate Change and the methodological recommendations of the Ministry of Natural Resources and Environment of Russia № 15p, through which the authors evaluated methane (CH4) and nitrogen oxide (N2O) emissions from solid waste disposal and from the treatment of liquid waste and effluents. Greenhouse gas emissions in 2020 were 1.57 mln. t CO2 equivalent, including 1.09 mln. t CO2-equivalent from solid waste disposal and 0.48 mln. t CO2 equivalent from liquid waste and sewage treatment. The main contributor to the growth of greenhouse gas emissions was emissions from solid municipal waste disposal, increasing by 0.06 million tons of CO2-equivalent over the past four years. Analysis of the current state and calculation has shown that the Novosibirsk Region has a low level of infrastructure development for separate waste collection, capacities of waste-sorting plants, as well as equipment of the centralized sewage system and quality of waste and effluent treatment. Therefore, it is necessary to introduce resource-saving and low-waste technology, the formation of a closed-cycle economy, the implementation of the transition to the multi-container separate collection of waste. It is advisable to disseminate technologies for collection of landfill gas and its use as fuel, the direction of organic waste for the production of commercial compost, biogas or feed and feed additives, as well as the development of technologies for obtaining biochar from organic waste and its further use in agriculture.
