International Journal of Research -GRANTHAALAYAH, 8(8), 1-14. https://doi.org/10.29121/granthaalayah.v8.i8.2020.730 Received Date: 13 July 2020 Accepted Date: 18 August 2020 Keywords: Food Waste Organic Compost Leachate Environmental Contamination ABSTRACT Composting is an important tool for recycling and proper disposal of organic waste. However, in small-scale composting, where total soil sealing and leachate collection is not carried out, elements such as P, Cu, Zn, Cd, Cr, Ni and Pb may accumulate in soil. This study aimed to assess phosphorus and heavy metal contents in soils of areas used for small-scale food waste composting. In order to do this, we sampled soil depths of 0-5, 5-10, 10-20, 20-30
