Aerobic Composting Essay

As the world continues to develop, one of the biggest setbacks of modernisation would be controlling the amount of waste produced. Hence, minimising waste generated or in other words, becoming green, is being emphasised by several developed countries and currently developing countries are too following suit. The adoption of composting addresses the challenges and opportunities to relief the world with waste issues. Compost is made through an aerobic process, or simply known as composting process, where microorganisms break down organic matter as a food source. The process pace of aerobic composting has an upper hand to be compared with anaerobic composting as there would be little to no problem in relation with pathogenic microorganisms (Konno and Machado, 2012). Tuomela,

Confusions aroused by these terms are avoided by using the basic distinction of reactor and non-reactor systems. The system which denotes the best technology is subjected on the nature of the feedstock and its volume, in hand with the environmental issues and the economical outcome (Keener, 2004; Finstein and Hogan, 1993). 2.2.1 Non-reactor Processes

Non-reactor systems of composting may also be termed as conventional or traditional composting. This is then separated between maintaining an agitated solids bed and a static bed. Agitated solids bed is when the composting mixture is disturbed in some way, may be by periodic tumbling, turning or agitation, during the composting phase.

2.2.1.1 The Windrow Process

Composting material is placed in rows and turned at regular schedules, commonly by mechanical equipment, for instance by the use of a tractor, pull-type turners handling, or straddle turners handling. The dimensions of the windrows differ depending on the nature of the feed material and the equipment used for
