Working of Modern Biogas Plants

An anaerobic digestion plant is a decentralized energy system, which can lead to self-sufficiency in heat and power needs, and at the same time reduces environmental pollution. The components of a modern anaerobic digestion plant include: manure collection system, anaerobic digester, effluent treatment plant, gas holder, and electricity generating equipment. The fresh organic waste is stored […]

Bioenergy Potential in Thailand

Thailand has tremendous biomass energy potential  with some studies projecting that biomass wastes can cover up to 15 % of the energy demand in Thailand. These estimations are primarily made from biomass waste from the extraction part of agricultural activities, and for large scale agricultural processing of crops etc. – as for instance saw and […]

Ten Golden Rules in Composting

It seems everyone is concerned about the environment and trying to reduce their “carbon footprint”.  I hope this trend will continue and grow as a nationwide way to live and not turn into a fad.  Composting has been around for MANY years. Composting is a great way to keep biodegradables out of the landfill and […]

What is Composting

The composting process is a complex interaction between the waste and the microorganisms within the waste. The microorganisms that carry out this process fall into three groups: bacteria, fungi, and actinomycetes. Actinomycetes are a form of fungi-like bacteria that break down organic matter. The first stage of the biological activity is the consumption of easily available sugars by […]

Methodology of Composting

The methodology of composting can be categorized into three major segments—anaerobic composting, aerobic composting, and vermicomposting. In anaerobic composting, the organic matter is decomposed in the absence of air. Organic matter may be collected in pits and covered with a thick layer of soil and left undisturbed six to eight months. The compost so formed may […]

Waste as a Source of Energy

Wastes can be transformed into clean and efficient energy and fuel by a variety of technologies, ranging from conventional combustion process to state-of-the art plasma gasification technology. Besides recovery of substantial energy, these technologies can lead to a substantial reduction in the overall waste quantities requiring final disposal, which can be better managed for safe […]

Biogas from Industrial Wastes

Organic waste includes a wide range of organic materials obtained from domestic, industrial and commercial operation. Most of the organic waste generated in developing countries is dumped into the landfills where it is not only responsible for large-scale greenhouse gas emissions, but also becomes a health hazard and creates all sorts of pollution. Source of Organic Wastes […]

Biomass Energy Prospects in Malaysia

Biomass is one of the most important sources of renewable energy in Malaysia. The National Biofuel Policy, launched in 2006 encourages the use of environmentally friendly, sustainable and viable sources of biomass energy. Under the Five Fuel Policy, the government of Malaysia has identified biomass as one of the potential renewable energy. Malaysia produces atleast […]

Biogas from Food Waste

Food waste management is a big problem in all countries, especially affluent ones. There are numerous places which generate large amounts of food waste including hotels, restaurants, malls, residential societies, canteens, airline caterers, markets etc. A proper food waste management strategy needs to be devised for them to make sure that either they are disposed off […]

Introduction to Vermicompost

Vermicomposting is a type of composting in which certain species of earthworms are used to enhance the process of organic waste conversion and produce a better end-product. Vermicomposting is a mesophilic process utilizing microorganisms and earthworms. Earthworms feeds the organic waste materials and passes it through their digestive system and gives out in a granular […]

Introduction to Hydrothermal Carbonization

Most would agree that the production of biofuels is important, even necessary, for our future. There are significant differences in the production of various biofuels, especially concerning the production of biocoal, which will impact the acceptance and use of biofuel in the future. This article focuses on one technology for the production of biocoal which […]
