“…By contrast, the average SOAV of the gas emitted from the biowindow surface was 1586 uo E /m 3 , with a range of 297-4526 uo E /m 3 . The results achieved by the biofiltration systems are similar to those found by Lee et al (2018) [3], ranging between 95.4-99%, and Capanema et al, (2014) [12], showing a removal efficiency close to 100% even with a grate variability of odor inlet load.…”

“…The presence of NMVOCs in landfill gas is mainly due to the process of volatilization of compounds present in the waste during the anaerobic degradation processes [7] and to a lesser extent to the composition of the waste (e.g., paints, adhesive glues and solvents) [8][9][10]. A widely used mitigation strategy is LFG recovery for energy utilization or flaring, but over time, LFG generation will decline to a level where utilization is no longer feasible [11,12].…”

Biofiltration systems are emerging technological solutions for the removal of methane and odors from landfill gas when flaring is no longer feasible. This work analyzed and compared two full-scale biofiltration systems: biofilter and biowindows. The emission mitigation of methane, non-methane volatile organic compounds (NMVOCs) and odors during a two-year management and monitoring period was studied. In addition to diluted methane, more than 50 NMVOCs have been detected in the inlet raw landfill gas and the sulfur compounds resulted in the highest odor activity value. Both systems, biofilter and biowindows, were effective for the oxidation of methane (58.1% and 88.05%, respectively), for the mitigation of NMVOCs (higher than 80%) and odor reduction (99.84% and 93.82% respectively). As for the biofilter monitoring, it was possible to define the oxidation efficiency trend and in fact to guarantee that for an oxidation efficiency of 80%, the methane load must be less than 6.5 g CH4/m2h with an oxidation rate of 5.2 g CH4/m2h.

“…LFG collection occurs for a part of the disposed MSW, which is defined by the scenarios. In this study, the LFG collection rate is assumed to reach 53% [48], while emissions from LFG combustion and flaring are assumed to be identical to those presented by Bacchi et al [49]. According to data from the Novyy Svet EKO landfill in the Leningrad region, energy recovered from LFG combustion displaces primary electricity production.…”

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

et al. 2022

A waste reform was recently introduced in Russia to divert waste from landfills. To help advance the reform, this paper presents a life cycle assessment of the municipal solid waste management system in Russia’s second largest city—Saint Petersburg—and its neighboring Leningrad region. Five scenarios were evaluated: the current state of the system (S0), its expected post-reform state in 2024 (S1), and its state improved by increased landfill gas collection (S2), by increased waste incineration (S3), and by separate collection of waste (S4). The environmental impact was assessed in terms of climate change, acidification, eutrophication, and abiotic resource depletion (fossil fuels). The results showed an overall reduction in the environmental impact of the waste management system across all impact categories and all scenarios studied. The largest reduction in all impact categories (except abiotic resource depletion) was achieved through source separation of municipal solid waste. Particularly, global warming potential was reduced from 0.328 kg CO2-eq./kg waste generated in S0 to 0.010 kg CO2-eq./kg waste in S4. Regarding abiotic resource depletion potential (fossil fuels), the incineration scenario is the most beneficial, since it reduces the impact by 573%.

“…In order to reduce the global warming potential (GWP) of MSW management, the European Union (EU) Land ll Directive (EU Directive 99/31/EC) was introduced in 1999 to decrease the amount of waste sent to land ll. (European Commission EC, 1999) (Bacchi et al 2018). EU member states are legally obliged to create and implement regional policy equipment to achieve these goals.…”

The aim of this study is to present the results of a life cycle assessment for several scenarios for municipal solid waste management in the European Union. After the entry into force of the European Union Landfill Directive, activities have been taken in succession to establish sustainable MSW management. A life cycle assessment was conducted to determine the environmental impact of municipal solid waste. To determine the environmental effect of various disposal and recovery methods, five different scenarios most commonly used in the European Union were compared: (1) 100% landfill, (2) 100% metals are recycled, remaining waste are sent to incineration, (3) 40% of organic and recyclable waste are composted and recycled, respectively and the remaining wastes are sent to landfill, (4) 100% of organic and recyclable waste are composted and recycled, respectively and the other wastes are sent to landfill, (5) 100% of organic and metal waste are composted and recycled, respectively and the remaining waste are sent to incineration. In Scenario-1, disposal methods contribute significantly to global warming and increase the environmental impact of non-carcinogenic substances. In order to reduce the negative impact on the environment in landfills, the recovery of electricity from methane gas has significantly reduced the potential impact of global warming. The results showed that Scenario-4 and Scenario-5 are more environmentally friendly compared to other scenarios.
