“…Food waste in Malaysia is categorized as solid waste under the Solid Waste and Public Cleansing Management Act 2007 (Act 672) (Hashim et al, 2021). The act was gazette in 2007 and enforced on 1st September 2011.…”

“…Nearly 80% of the food waste generated was being disposed in landfill. Although landfilling is listed as the most undesirable option method for waste disposal, however it is still remained as the most preferred selection due to its cost efficiency and low technical requirement (Hashim et al, 2021). However, landfill in Malaysia is soon reaching its capacity and it is difficult to continue disposing waste into it.…”

“…Methane gas and carbon dioxide contributes impacts towards the environment during landfilling. Methane gas is the main agent causes for ozone depletion, 21 times more harmful than carbon dioxide (Hashim et al, 2021). It is the poor food waste management that leads to pollution towards the environment including air, soil and water.…”

Food waste in Malaysia has the highest composition in municipal solid waste (MSW) stream which, occupied around 44.5% of the total waste in mass. As food wastes are commonly disposed to landfill, during the process of degradation, it produces harmful pollutants such as leachate which cause contamination to the water sources while landfill gases lead to global warming and climate change. However, land scarcity is an issue in Malaysia where it is soon coming into a limit in spaces for landfilling. Hence, it is vital to look into a suitable food waste management method upon the issues. The application of Multi Criteria Decision Making (MCDM) is important in assisting the decision-making process by suggesting suitable food waste management treatment method. It helps to select shortlisted criteria that fulfill the requirements in line with the preferences and suggest on suitable treatment selection for decision. Analytical Hierarchy Process (AHP), which is one of the MCDM techniques, able to provide a rational decision-making framework by incorporating many relevant criteria and alternative that is support by scientific values of the suggestion. With the aid of the decision-making technique, food waste can be properly managed through suitable management treatment method and promotes on circular economy, reducing impacts towards the environment. From the results analyzed through MCDM, it is encouraged to practice on Anaerobic digestion (AD) treatment as it results in significant reduction of impact towards the environment. The use of AD treatment has significantly show contribution towards the environment. This study allows in showing on how food waste can be management properly in the suitable and preferred method that allows in the reduction of environment pollution.

“…Although numerous campaigns and efforts have been put forth in managing household food wastes via composting approach, many did not compost mainly due to financial constraint, low awareness in segregating the food wastes correctly as well as limited knowledge in composting (Hashim et al, 2021). Other reasons making the public reluctant to compost include odor issues, lack of space/facilities, start-up cost of composting and some did not see the importance in composting.…”

“…A survey conducted between May 8, 2020 and May 19, 2020 by Malaysian Solid Waste and Public Cleansing Management Corporation (SWCorp), a governmental agency managing the country's wastes, revealed that the main culprits contributing to food wastes were unconsumed and spoilt food accounting up to 70% of the total wastes (TheStar, 2020). Although numerous campaigns and efforts have been put forth in managing household food wastes via composting approach, many did not compost mainly due to financial constraint, low awareness in segregating the food wastes correctly as well as limited knowledge in composting (Hashim et al., 2021). Other reasons making the public reluctant to compost include odor issues, lack of space/facilities, start‐up cost of composting and some did not see the importance in composting.…”

To elucidate the efficacy of eco-enzyme in mediating contaminated waters, an onsite investigation was conducted spanning over a 5-month duration on three ponds receiving iron-containing groundwater continuously. Eco-enzyme was applied at designated dosages and time. Water samples were collected fortnightly for in situ monitoring of water quality. Parameters determined included total suspended solids (TSS), pH, alkalinity, chemical oxygen demand (COD), biochemical oxygen demand (BOD 5 ), ammoniacal-nitrogen (NH 3 ), and dissolved oxygen. During the investigation, ecoenzyme application was halted for nearly a month owing to the enforcement of Movement Control Order to curb the rising Covid-19 cases. The results revealed that the application of eco-enzyme has improved the overall water quality of the three ponds.A 99.9% of TSS removal was achieved. For the other parameters measured, the concentration fluctuated over time and the water quality status of the pond interchanged between slightly polluted and clean. The elevation of the water quality was largely dependent on the frequency of the eco-enzyme application. This study, therefore, concludes that eco-enzyme possessed the capability to enhance the quality of contaminated water.
