Composting has been occurring naturally with the decomposition of organic matter by microorganism and is the best technique in yard waste management to produce landscape fertilizer. This article discusses the management of yard waste in UKM and determines the feasibility of using windrow composting for mixed yard and food wastes. The amount of yard waste generated in Universiti Kebangsaan Malaysia (UKM) approximately is 2.36 tonne/day. An estimated the total of 3.36 tonne of yard and food waste is generated per day at UKM, which would require 8 rows of 42-meter long windrows. The contents of the windrows are periodically turned (mixed) to ensure homogeneity, increase porosity and to assist aeration. This study complements the concept of the UKM Zero Waste Campus by producing a valuable material from waste.
