Simulated kitchen waste was developed in this study to overcome the problem of kitchen waste variation composition. The performance of organic acids production was compared between the simulated kitchen waste and original kitchen waste. Both substrates were subjected to anaerobic digestion by indigenous mixed microflora from fermented kitchen waste in a 250 mL shake flasks. The condition used w...

Kitchen wastes containing high amounts of carbohydrates have potential as low-cost substrates for fermentable sugar production. In this study, enzymatic saccharification of kitchen waste was carried out. Response surface methodology (RSM) was applied to optimize the enzymatic saccharification conditions of kitchen waste. This paper presents analysis of RSM in a predictive model of the combined ...

Abstact: The aim of the research project was to carry out the co-digestion of organic fraction of solid municipal waste in the form of source separated kitchen waste and sewage sludge. The influence of the kitchen waste as a co-substrate on the stability and efficiency of the process was determined. Mesophilic fermentation (36 ̊C) was conducted for sewage sludge as well as mixtures of sewage slu...

Large quantities of kitchen waste are produced in modern society and its disposal poses serious environmental and social problems. The aim of this study was to isolate degradative strains from kitchen waste and to develop a novel and effective microbial agent. One hundred and four strains were isolated from kitchen waste and the 84 dominant strains were used to inoculate protein-, starch-, fat-...

Kitchen waste (food waste) collected from hostels and canteen has high calorific and rich nutritive value to microbes due to which efficiency of methane production can be enhanced. Biogas (Green energy) as an energy source is cost effective and generates a high-quality renewable fuel. Biogas contains around 55-65% of methane, 3040% of carbon dioxide. Methane has a calorific value of 10 kWh/Nm 3...

Vermicomposting using Lumbricus rubellus for 49 days was conducted after 21 days of pre-composting. Three different combination of treatments were prepared with eight replicates for each treatment namely cow dung: kitchen waste in 30:70 ratio (T(1)), cow dung: coffee grounds in 30:70 ratio (T(2)), and cow dung: kitchen waste: coffee grounds in 30:35:35 ratio (T(3)). The multiplication of earthw...

Composting is a good recycling method to fully utilise all the organic wastes present in kitchen waste due to its high nutritious matter within the waste. In this present study, the optimised mixture proportions of kitchen waste containing vegetable scraps (V), fish processing waste (F) and newspaper (N) or onion peels (O) were determined by applying the simplex-centroid mixture design method t...

Households in the UK discard much food. A reduction in such waste to mitigate environmental impact is part of UK government policy. This study investigated whether household food waste is linked to a lifestyle reliant on convenience food in younger consumers. A survey of 928 UK residents aged 18-40 years and responsible for the household food shopping (male n = 278; female n = 650) completed an...

Resource recovery and recycle of organic waste is a major concern now-a-days all over the world. This present study deals with the Microbial Fuel Cells (MFC) using kitchen garbage to produce electricity as well as recycle of organic waste and its potential use in Bangladesh. A rectangular acrylic container (10 x 10 cm) was used as the cell. The container was filled with well mixed kitchen garba...
