In terms of sustainable development, compost production is interesting because it creates new soil improvement. Public policies encourage this practice because it reduces the mass of waste to treat by thermal process or by landfilling. In developed countries such as Europe, the generation of municipal solid waste is still growing because of economic prosperity, urbanization and consumer marketing pressures. This waste production will increase by 45% in 2020, as compared to 1995 (source Organisation for Economic Cooperation and Development. Municipal wastes are composed of around 30 % of biodegradable organic waste. This organic part can be managed with home composting. But home composting could be difficult to implement because of biodegradation management problems and odours emissions. Therefore, home composting has to be studied in order to propose the best way to manage it without environmental impacts. One of the first problem to address concerns to biodegradability of the waste to be treated by home-composting. During this study, various mixtures of food waste (FW) and yard trimmings (YT) i.e. grass clippings; and FW and inert bulking agent; BA (i.e. inert packing material) have been tested by using respirometric cells to compare biodegradability of these formulations as a function of time under the influence of physical and chemical charactéristics.
