The potential of bioreactor landfills to treat mechanically biologically treated municipal solid waste is analysed in this study. Developing countries like India and China have begun to investigate bioreactor landfills for municipal solid waste management. This article describes the impacts of leachate recirculation on waste stabilisation, landfill gas generation, leachate characteristics and long-term waste settlement. A small-scale and large-scale anaerobic cell were filled with mechanically biologically treated municipal solid waste collected from a landfill site at the outskirts of Bangalore, India. Leachate collected from the same landfill site was recirculated at the rate of 2–5 times a month on a regular basis for 370 days. The total quantity of gas generated was around 416 L in the large-scale reactor and 21 L in the small-scale reactor, respectively. Differential settlements ranging from 20%–26% were observed at two different locations in the large reactor, whereas 30% of settlement was observed in the small reactor. The biological oxygen demand/chemical oxygen demand (COD) ratio indicated that the waste in the large reactor was stabilised at the end of 1 year. The performance of the bioreactor with respect to the reactor size, temperature, landfill gas and leachate quality was analysed and it was found that the bioreactor landfill is efficient in the treatment and stabilising of mechanically biologically treated municipal solid waste.

Solid Waste Treatment

Despite the National Policy for Solid Waste (PNRS) in 2010, nothing has changed to the waste disposal in Brazil. Planned to reach 100% of all Municipal Solid Waste (MSW) collected and treated in landfills by Aug. 2 nd, 2014, until nowadays, 42% of this total remains in dumps. Even the most important national economic region treating its urban waste in landfills, what it has is no more than 4% of recycling and its landfills reaching the exhaustion.

Murmansk Region

Most municipal solid waste (MSW) in Russia is disposed of in landfills, and only a relatively small fraction is recycled. The landfilling of waste leads to greenhouse gas (GHG) emissions, and air and groundwater pollution. However, recently, there have been some initiatives to improve waste management in the country. We assessed the economic and environmental benefits of waste recycling in the Murmansk region, in which a new waste recycling plant has been operating since 2019. We found that MSW recycling in the Murmansk region has induced a small, positive, job creation effect and could potentially lead to a non-negligible reduction in GHG emissions. Extrapolating the results from this case study to the country level, we found that recycling landfilled MSW in Russia could save approximately 154 million tons of GHG emissions in carbon dioxide equivalents annually, which is comparable to the total CO2 emissions from Algeria. The positive environmental and health-related impacts from the extensive implementation of MSW recycling in the country could be substantial. From this case study, we also learned that one of the biggest challenges for the waste recycling company in the Murmansk region is finding profitable markets for recycled materials. Moreover, due to the high investment and operational costs, recycling MSW led to a substantial increase in communal fees. However, there is potential to make waste recycling more cost effective. Most MSW in the Murmansk region is still separated at the recycling plant, while separating waste at the source could substantially reduce operational costs. Other challenges in the large-scale implementation of MSW recycling in Russia, such as a lack of investments and the population’s willingness to recycle waste, are also discussed.
