In-vessel Composting of Vegetable Waste and Compost Application Trial on Lettuce (Lactuca Sativa L.)

Abstract

The increasing transportation costs of the vegetable waste generated from wholesale markets in Vietnam propose a decentralized waste treatment approach as in-vessel composters for more effective recycling of organic waste into valuable composts. Two in-vessel composters (rotary drum reactors-RDR and aerated cubic boxes-ACB) were designed to study different composting mixtures, consisting of 70 % (v/v) vegetable waste (VW) and 30 % additives (either napier grass–NG or corncob-derived biochar–CB and sugarcane bagasse–SB).
