Environmental evaluation of waste treatment scenarios for the towns Khanty-Mansiysk and Surgut, Russia

Abstract

Khanty-Mansiysk Autonomous Okrug - Ugra in Siberia has recently started to play a major role in the Russian economy because key oil and gas extraction sites are located in this region. As a result, the extensions of infrastructure and higher incomes have been leading to an accelerated population growth and consequent increase in the generation of solid household waste. The current methods of waste disposal have now reached their limits, especially in the towns Khanty-Mansiysk and Surgut. The key objectives of this study were to identify the influence of waste composition and transport routes on the life cycle assessment (LCA) results and to assess the current waste treatment option for solid household waste and to compare it with proposed scenarios. Furthermore, recommendations for an optimal use of LCA within a decision-making process for a waste management plan are presented. LCA methodology was used to evaluate different waste management scenarios such as landfilling and incineration. One result was that the options 'incineration with recycling' and 'anaerobic mechanical-biological treatment with recycling' demonstrated lower environmental impact in both Khanty-Mansiysk and Surgut. Another finding was that there were hardly any differences in the ranking of the scenarios for Surgut and Khanty-Mansiysk. However, the special socio-cultural circumstances and location of each town have to be considered seriously in the development of a sustainable waste management plan.

Life Cycle Assessment of Existing and Alternative Options for Municipal Solid Waste Management in Saint Petersburg and the Leningrad Region, Russia

“…This study further supports the claim that the diversion of waste from landfills benefits the environment, which is a finding similar to the results of other studies, e.g., Bohra et al [22], Kaazke et al [28], and Starostina et al [27]. Furthermore, this study indicates that systematic changes aimed at the implementation of MSW source separation (including their consequent recycling) and incineration have greater potential for the reduction of environmental impact compared to incremental improvements of existing MSW management systems through increased sorting of mixed waste and introduction of LFG collection.…”

“…Given the sparse use of LCA methodology in Russia in general, LCA studies on waste management systems are rather limited. Never-theless, a few LCAs have been published for other Russian cities [26][27][28][29] including a recent LCA study on Moscow [30].…”

“…A similar study using the LCA was carried out by Kaazke et. al (2013) for Khanty-Mansiysk and Surgut.…”

Landfill restoration and biodiversity: A case of study in Northern Italy

“…Landfilling is the most common method in the world for hazardous waste disposal (Dung et al, 2014;Kaazke et al, 2013;Klein et al, 2001). The main purpose of a landfill recovery programme is to reach determined public health standards, but aesthetic and landscape features are also important (Simmons, 2008;Tarrant et al, 2012) when the landfill has to be restored after final sealing.…”
