Conversion of Food Wastes into Compost for Home Gardening and Reduction of Global Warming on households in Zaria, Kaduna State Nigeria

means of reducing global warming in households in Zaria, Kaduna State, Nigeria. Food waste is a normal occurrence in households and food industries which happens on a daily basis. In Nigeria more than 50% of wastes generated is organic therefore, proper management of organic wastes will significantly decrease the amount of pollution arising from poor waste management such as combustion. Improper disposal of food waste has a negative impact on the global climate system, when food wastes are disposed, they generally end up in landfills and emit methane while decomposing. Methane is a greenhouse gas that is more potent than carbon dioxide (C02 ) and this negatively impacts the environment. The problem of food waste in landfill poses great threat to human health, environment and has a negative impact on the global climate system. Food wastes can be prevented from ending up in the landfill by recycling food wastes into composts for fertilizing plants. The study was guided by 3 objectives. The study area was Zaria metropolis located in Sabon-Gari, Kaduna state, Nigeria. Experimental research design was adopted for this study; food wastes were disposed into pits and left to decompose for 18 days. In step I: various types of food wastes were collected, step II: food wastes were separated considering the various moisture content, step III: 1.0m long, 1.0m wide and 0.2m depth pit was dug and food wastes were disposed into the pit. After 18 days, the compost that had already turned black was used to fertilize crops and the harvest were used by the researchers to fertilize plants. Converting food wastes to compost has a positive impact on the global climate system. Compost is also economical, environmentally friendly, and reduces greenhouse gas emissions. It was recommended that composting food waste should be adopted by households in Nigeria as a means of fertilizing plants in gardens, composting in the communities should be undertaken in households by different age groups using simple implements. Home Economists should learn how to produce compose from food waste to fertilize plants in the home garden and the compost can also be packaged and sold in kilograms during the dry season to supply manure to the farms around the metropolis.
