Food waste has become a serious issue in recent years. Due toincrease in over population, solid waste also more generated and affect public health and environment. Food wastes produce methane gas that results greater impact on global warming than carbon dioxide. The composting technology is one of the alternatives, as it is the highest form of recycling of biodegradable solid waste. The study was undertaken to utilize food waste generated, into organic manure using effective micro-organism. A total of 100 kg of food wastes were collected from 100 households in Allahabad over 15 days. The pit was dug for composting using Effective Microorganisms (EM) and natural composting for remediation of organic contaminants. The compost was analyzed and the effectiveness of compost was studied through cultivation of vegetables at households. Results revealed that EM compost had fast decomposition rate, rich in nutrients, more microbial activities, good germination and more yields compared with natural compost. Thus, the study paves way for effective management of food waste in order to minimize potential human and environment risks and composting using effective microorganisms as an option of waste management operation that is cheap, Eco- friendly and sustainable.

The problem of food waste and waste is a major problem that should be examined not only in terms of economic but also ecological and sociological importance. Considering the decrease in natural resources and the pollution caused by it, the importance of the effective management and re-evaluation of food wastes should not be overlooked. The data in the studies support the increasing hunger. The data in the studies support the knowledge that hunger is increasing. In order to combat hunger: urgent measures should be taken, and ways of regaining waste food or waste food should be explored. The problem requires global responsibility. The purpose of the research is to share remarkable data and research, to provide information about food waste types, to raise awareness of all relevant stakeholders to come together to solve the problem. Also in the study: the findings of the application developed with the algorithm of the established model are shared and it is aimed to shed light on the next studies.

Socio Demographic Factors

Most local authorities in Malaysia spent as much as 60-70 percent of their annual budget to dispose food waste together with other municipal solid wastes to landfills. It is time for Malaysians to start reducing food waste through sustainable method, as it is becoming an uphill task to manage food wastes generated in Malaysia. When households reduce the amount of food waste generated in a sustainable way, it could help reduce cost, and other related bills for households, and as well in running their other daily activities. The main objective of this study is to assess how sociodemographic factors of households in Selangor and Terengganu influence their behaviour towards participation in sustainable food wastes management program. The study applied purposive nonrandom sampling consisting of 333 respondents, 257 were from Selangor and 76 from Terengganu. Primary data was collected through structured questionnaire. Descriptive and logistics regression model analysis were used to analyze the data. Findings have shown 48.7 percent of Terengganu respondents spent not more than RM100 on food per week, while Selangor had 41.2 percent within the same period who spent such amount. 35.4 percent of Selangor respondents spent between RM101-200 compared to Terengganu which spent same amount at 30.3 percent within the same periods. The survey shows 43.2 percent of Selangor households disposed 1-3kg food wastes, while Terengganu on the other hand had 51.3 percent who disposed same quantities of food wastes per week. Respondents with higher education, those on government jobs, small family size and ethnicity have significant impacts on the respondents' behaviour towards participation in sustainable food waste management program.

Environment And Health

Solid waste known as garbage still becomes one of the most concerning issues   in Indonesia. It increases every year; however, the landfill was not expanded. The accumulation of garbage could give a negative impact on the environment and health. Due to this reason, there is an alternative suggested to reduce the garbage and its sources. The initiative called ‘Bank sampah’, itis a garbage treatment system which is managed by the community. In addition, the Reduce, Reuse, Recycle (3R) laystall was built to carry out some ‘Bank Sampah’. This study conducted a preliminary design of 3R laystall at Desa Karyamulya Kecamatan Cisaga Kabupaten Ciamis.  The design of the 3R laystall using black soldier fly method to decompose organic materials is employed in this research. The quantity and the density of the garbage were required to determine the design of the lay stall. Stratified random sampling was conducted for 8 days. Desa Karyamulya generates 2.361 liters/person/day or 0.236 kg/person/day. According to a population projection for the next 10 years, the estimation of garbage composition consists of food waste (52.15%); plastic (23.58%); paper (9.23%); fabric (0.45%); wood/leaf (6.38%); diapers (2.85%); metal (0.94%); rubber/leather (2.19%); glass (0.17%); and styrofoam (2.04%). From the quantity and composition of the garbage, it requires approximately  94 m2 of the area and an  estimated  funds needed as Rp. 483.908.600

Investigation Process

Waste recovery is an important aspect towards human and environmental health protection. Unfortunately, proper food waste management is among the serious challenges in the field of solid waste management worldwide. Therefore, it is of great importance to conduct studies towards achieving efficient and cost-effective approaches for food waste management. This study investigated the potential of recovering food waste through maggots’ production as animal feed. The influence of fly attractant application on maggot production was also investigated. The study also investigated the potential of maggot production for waste recovery and reduction. Four different types of food waste (starch food leftovers, rotten bananas and peels, rotten pineapple and peels, and rotten oranges) were used in the investigation process. From the results, it was observed that the application of fly attractants had a significant effect on the production of maggots as determined by the weights after harvesting. Average weight of 94 g/kg of maggot was achieved from banana materials with an application of fly attractant during the 8th day of the cultivation; which is equivalent to a 32.4% increase from the same day when the material was cultured without applying fly attractant. Also, from the starch materials, about 77 g/kg of maggot weight was achieved; which is a 54.6% increase from the same day and the same material but without application of fly attractant. Moreover, the relative dry weight reduction in the trials varied from 52.5% to 82.4%.

Biotechnology for intensive aerobic bioconversion of sewage sludge and food waste into fertilizer was developed. The wastes were treated in a closed reactor under controlled aeration, stirring, pH, and temperature at 60¡C, after addition of starter bacterial culture Bacillus thermoamylovorans. The biodegradation of sewage sludge was studied by decrease of volatile solids (VS), content of organic carbon and autofluorescence of coenzyme F420. The degradation of anaerobic biomass was faster than biodegradation of total organic matter. The best fertilizer was obtained when sewage sludge was thermally pre-treated, mixed with food waste, chalk, and artificial bulking agent. The content of volatile solid and the content of organic carbon decreased at 24.8% and 13.5% of total solids, respectively, during ten days of bioconversion. The fertilizer was a powder with moisture content of 5%. It was stable, and not toxic for the germination of plant seeds. Addition of 1.0 to 1.5% of this fertilizer to the subsoil increased the growth of different plants tested by 113 to 164%. The biotechnology can be applied in larger scale for the recycling of sewage sludge and food wastes in Singapore.
