Overview of Biomass CHP

Biomass CHP is the simultaneous generation of multiple forms of useful energy (usually mechanical and thermal) in a single, integrated system using biomass wastes. Biomass conversion technologies transform a variety of wastes into heat, electricity and biofuels by employing a host of strategies. Conversion routes are generally thermochemical or biochemical, but may also include chemical and physical. […]

There are so many rings through which you must jump and so many policies with which you must keep up to date. Of course, it’s becoming clearer and clearer […]

Waste-to-Energy Industry Trends

The quantity of waste produced all over the world amounted to more than 1.3 billion tonnes in 2012, with estimates of up to 2.2 billion tonnes by 2025. The rapid increase in population coupled with changing lifestyle and consumption patterns is expected to result in an exponential increase in solid waste generation. Ironically, most of […]

CDM Prospects in Middle East and North Africa

The Middle East and North Africa region is highly susceptible to climate change, on account of its water scarcity, high dependence on climate-sensitive agriculture, concentration of population and economic activity in urban coastal zones, and the presence of conflict-affected areas. Moreover, the region is one of the biggest contributors to greenhouse gas emissions on account […]

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 […]

What is Biomethane

The typical composition of raw biogas does not meet the minimum CNG fuel specifications. In particular, the CO2 and sulfur content in raw biogas is too high for it to be used as vehicle fuel without additional processing. Biogas that has been upgraded by removing H2S, moisture and carbon dioxide is known as biomethane. Biomethane is […]

What is Trigeneration

Trigeneration or CCHP (combined cooling, heat and power) refers to the simultaneous generation of electricity and useful heating and cooling from the combustion of a biomass fuel or a solar heat collector. Conventional coal or nuclear-powered power stations convert only about 33% of their input heat to electricity. The remaining 67% emerges from the turbines as low-grade waste […]

Bioenergy in Middle East and North Africa

There is a large potential for renewable resources in the Middle East which have remained more or less unharnessed. Apart from solar and wind, the Middle East also has abundant biomass energy resources which have remained unexplored to a great extent. According to conservative estimates, the potential of biomass energy in the Euro-Mediterranean region is […]

Renewable Energy in South Africa

South Africa, the most industrialized country in Africa, is highly dependent on conventional fuels which make it one of the largest emitters of greenhouse gases in the world. Coal provides around 75% of the fossil fuel demand and accounts for 90% of power generation in the country. A smooth transition to a low-carbon society requires […]

Natural Gas: A Feasible Alternative to Diesel Fuel

Our dependency on fossil fuels has become a hotly debated topic over the past few years, and many industries are now turning to alternative fuels in an effort to protect the planet from harmful emissions. Natural gas has emerged as a forerunner in the field of alternative transportation fuels, and many drivers, both commercial and […]

Lebanon Climate Act

Lebanon Climate Act is being organized in line with its INDC, country’s climate change engagement at COP21. Lebanon’s INDC is the Intended Nationally Determined Contribution where Lebanon has publicly outlined what climate actions it intends to take under a new international agreement by 2030, and has mainly set a target of 15% CO2 emissions reduction […]

Harmful Effects of Healthcare Wastes

There has been a growing awareness of the need for safe management of healthcare waste all over the world. Healthcare wastes which pose the greatest risk to human health are infectious waste (or biomedical waste) which constitutes 15 – 25 percent of total healthcare waste. Infectious wastes may include all waste items that are contaminated […]

Wastes from Leather Tanning

Tanning refers to the process by which collagen fibers in a hide react with a chemical agent (tannin, alum or other chemicals). However, the term leather tanning also commonly refers to the entire leather-making process. Hides and skins have the ability to absorb tannic acid and other chemical substances that prevent them from decaying, make […]

Solutions for Achieving Power Back-Up

Protecting the power supply to your vital IT, security and other systems is a key part of keeping your business going in the event of mains-supply problems. It’s always the unexpected that catches you out and a simple loss of mains power – even a brief interruption – can lead to lost data and even […]

A Primer on Biodiesel

Biodiesel is a clean burning alternative fuel produced from domestic, renewable resources. The fuel is a mixture of fatty acid alkyl esters made from vegetable oils, animal fats or recycled greases. Where available, biodiesel can be used in compression-ignition (diesel) engines in its pure form with little or no modifications. Biodiesel is simple to use, […]

Storage Systems for Biomass

Sufficient storage for biomass is necessary to accommodate seasonality of production and ensure regular supply to the biomass utilization plant. The type of storage will depend on the properties of the biomass, especially moisture content. For high?moisture biomass intended to be used wet, such as in fermentation and anaerobic digestion systems, wet?storage systems can be […]
