“…The life cycle impact assessment (LCIA) categories considered were selected based on relevance [ 88 ], existing literature [ 78 ] and geographic region [ 3 ]. These include: Climate change human health (CC), ozone depletion (OD), human toxicity (HT), photochemical oxidant formation (POF), agricultural land occupation (ALO), natural land transformation (ME), and fossil depletion (FD).…”

“…LCA has been frequently applied to assess FW treatment options such as landfilling, composting, incineration with or without energy recovery, recycling, and a combination of various scenarios [ 2 , 3 , 18 , 27 , 31 , 43 , 55 , 92 , 98 ]. FW has been used as feedstock to produce different biomaterials, bioenergy, and other high-value products [ 39 , 104 , 133 , 136 ].…”

This study applies a triple bottom line (TBL) framework that incorporates the environmental, economic, and social impacts of producing animal feed from food waste (FW) collected at the post-consumption stage of the food supply chain. The environmental bottom line (BL) is conducted using life cycle assessment (LCA), the economic BL is calculated using the net present value (NPV), while the social BL is assessed using the strengths, weaknesses, opportunities, and threats (SWOT) analysis. The results within the environmental BL indicate that at a 13.8% recovery rate, animal feed produced from a ton of FW saves 0.33 m 2 equivalent of crop land but requires 3.5 tons of water compared to 0.9 tons and 0.78 tons for landfilling and incineration for FW treatment respectively. In addition, the production of animal feed from one ton of FW emits 1064.6 kg CO 2 -eq, compared to 823.6 kg CO 2 -eq using landfilling and 781.9 kg CO 2 -eq when incinerated. The economic BL indicates a profit of $3.65/ton from incinerating FW, compared to cost of $93.8 and $137.6 per ton for animal feed production and landfilling of FW respectively. The analytic hierarchy process (AHP) is applied to integrate the TBL scores and rank the scenarios accordingly. AHP recommends animal feed and incineration over landfilling by a fourfold higher score. A simulation using an augmented simplex lattice mixture (ASLM) design recommends incineration with energy recovery over animal feed production from FW collected at the consumer stage. Sensitivity analysis indicates that the production of animal feed from FW is environmentally feasible if the safe recovery rate exceeds 48%, is which possible for FW collected at early stages of the food supply chain.

“…Several methods have been used in the assessments of the waste management practices in GCC countries. A lifecycle assessment [39] and a driver-pressure-state-impact-response framework [40] have been used in Kuwait, a multicriteria analysis (MCA) has been used in Oman [38], and WtE technologies have been assessed in Saudi Arabia [41,42]. Anaerobic digestion (AD) was found to be the most suitable option for Saudi Arabia because of the large contribution of organic material to MSW in Saudi Arabia [43].…”

Mitigating climate change to limit the global temperature increase (relative to pre-industrial temperatures) to 2 °C is receiving considerable attention around the world. Here, historical and future carbon dioxide equivalent (CO2e) emissions from municipal solid waste (MSW) in Bahrain were calculated using the revised Intergovernmental Panel on Climate Change (IPCC) 1996 and IPCC 2006 methods. The extent to which waste-to-energy (WtE) technologies can contribute to climate change mitigation was assessed by performing a multicriteria analysis. The results indicated that CO2e emissions from MSW in Bahrain have been increasing since the Askar landfill was constructed in 1986. Emission recalculations indicated that CO2e emissions from MSW contribute 6.2% of total emissions in Bahrain rather than the 11.6% reported in the second national communication. Methane emissions from MSW in 2030 are predicted to be 22–63 Gg. The WtE technologies anaerobic digestion and landfill gas recovery gave the best and gasification the worst multicriteria analysis model results. A database of WtE plants around the world should be compiled to allow decisions around the world to be based on best practices. The potential for maximizing energy recovery and decreasing costs needs to be investigated to allow WtE plants to compete better with renewable and nonrenewable energy sources.

“…A clear trend towards the application of the lifecycle assessment method can also be observed where [8] first updated the baseline for household waste composition. Then, they used the survey results to inform the conduct of a lifecycle assessment to the MSW in Kuwait [9]. This assessment was based on the environmental impacts mainly where the meteorological conditions and geological formations were used to inform six scenarios to obtain…”

The management of municipal solid waste (MSW) appears as a challenge for many countries in the world. The rapidly increasing amounts of waste and the consequent potential impacts necessitate proper planning and management. This paper assesses the management of the MSW in Kuwait using the driving forces-pressures-state-impacts-responses (DPSIR) framework. Applying the DPSIR method allows for understanding the causes behind the current state related to MSW along with the potential impacts and responses undertaken so far. The results of the analysis show that the generation of MSW is highly correlated with the population and economic growth in Kuwait. The per capita MSW is relatively high reaching 1.6 kg/capita/year. There are several potential impacts associated with the current practices of MSWM in Kuwait. Yet, only few of them have been assessed. Kuwait has enacted the Environmental Protection Law No. 42 in 2014 where the management of the MSW is emphasized. This paper recommends the calculation of a number of waste-related performance indicators. It also recommends the conduct of a social survey for a better understanding of the consumption patterns and variations associated with the different population groups and seasons. Finally, the initiation of a regional waste-related network is highly recommended to foster collaboration and share best practices with other Gulf Cooperation Council countries.
