Anatomy of a Recycling Facility

We separate recyclables from trash. We take our containers out to the curb on collection day. Trucks empty them and drive off. We retrieve the containers until the next collection day. Did you ever wonder what happens next? To find out, I toured the recycling facility in Greensboro, North Carolina and interviewed the city’s recycling […]

New Delhi’s Tryst with Rubbish

Have you seen the several storeys high landfill in Delhi at its border with Uttar Pradesh – Gazipur, a prime land! It’s a mountain of garbage now. How does the garbage reach the landfill and what will happen when this place is all filled up? Does our food waste also contribute to our garbage mountains? May be we all […]

Waste Crisis in Lebanon

Solid waste management in Lebanon has been hogging limelight globally in recent years. Unfortunately, Lebanon is struggling to solve the waste crisis with no permanent solution in sight.  The organic content in Lebanese MSW is around 50-55% which makes it a well-suited for composting and anaerobic digestion. Recyclables content is also good, though recycling is […]

Waste to Energy in Jordan

Waste-to-energy is getting increasing attention in Jordan because of the cheap and abundant availability of a wide range of biomass feedstock, including municipal solid waste, sewage, industrial waste etc. Municipal solid wastes represent the best feedstock for waste to energy plants  in Jordan. In terms of quantity per capita and constituents, the waste generated in […]

Role of Waste-to-Energy in SWM

According to recent estimates, the rapid increase in population coupled with changing lifestyle and consumption patterns is expected to result in an exponential increase in global waste generation of up to 18 billion tonnes by year 2020. Ironically, most of the wastes are disposed of in open fields, along highways or burnt wantonly. Waste generation […]

BinStrap – Securing Trash Bins

Every year eight million tonnes of plastic enter our ocean, BinStrap is committed to dramatically reducing this number simply by securing wheelie bin lids. BinStrap is a patented device that was designed with the intention of securing the 1.5 Billion Unsecured wheelie bins worldwide that are spilling plastic and rubbish into our environment, rivers and […]

Exploring Gasification of Solid Wastes

Gasification of solid wastes involve the reaction of carbonaceous feedstock with an oxygen-containing reagent, usually oxygen, air, steam or carbon dioxide, generally at temperatures in excess of 800°C. It involves the partial oxidation of a substance which implies that oxygen is added but the amounts are not sufficient to allow the fuel to be completely oxidised […]

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 […]

Waste-to-Energy Conversion Routes

The conversion of waste material to energy can proceed along three main pathways – thermochemical, biochemical and physicochemical. Thermochemical conversion, characterized by higher temperature and conversion rates, is best suited for lower moisture feedstock and is generally less selective for products. On the other hand, biochemical technologies are more suitable for wet wastes which are […]

Techno-commercial Aspects of Composting

The composting plants consist of some or all of the following technical units: bag openers, magnetic and/or ballistic separators, sieves, shredders, mixing and homogenization equipment, turning equipment, aeration systems, bio-filters, scrubbers, control systems etc. One of the most important equipment is the machinery used to turn the windrows. Either a standard front-end loader or a […]

Easy Ways to Recycle

If you want to reduce your carbon footprint in a way that can instantly benefit our planet, you should look into recycling. Thanks to increased awareness, we’re now recycling more than ever. If you’re wondering why and how to recycle, this article is for you. Why you should recycle Recycling is so important because of […]

Quick Glance at MSW-to-Energy Systems

Reduction in the volume and mass of solid waste is a crucial issue especially in the light of limited availability of final disposal sites in many parts of the world. Waste-to-Energy (WTE) or Energy-from-Waste (EfW) is the use of modern combustion and biochemical technologies to recover energy, usually in the form of electricity and steam, from urban […]

Enumerating Advantages of RDF

Solid waste is a growing problem in all countries, and a critical problem in almost all the cities of the developing world. Developed countries have in recent years reduced the environmental impact of solid waste through sanitary landfills and high-temperature incineration, as well as conserving natural resources and energy through increased recycling, but the volume […]

Few Words on Landfill Gas

Landfill gas (or LFG) is an asset as well as a serious threat. If we extract it right on time and preserve it then it will act as a valuable asset and if we leave as it is then it will be a serious threat as it can explode at any time. Landfill gas is […]

Quick Summary of Waste-to-Energy Processes

A wide variety of conversion methods are available for realizing the potential of waste as an energy source, ranging from very simple systems for disposing of dry waste to more complex technologies capable of dealing with large amounts of industrial waste.  These methods can be broadly divided into thermal and biological processes. Some of the […]

Significance of Solid Waste Management

Some countries have achieved considerable success in solid waste management. But the rest of the world is grappling to deal with its wastes. In these places, improper management of solid waste continues to impact public health of entire communities and cities; pollute local water, air and land resources; contribute to climate change and ocean plastic […]

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 […]

Garbage Woes in India

An American produce 2.1 kg of garbage per day against 0.6 kg for an Indian, according to a 2009 study by the National Sanitary and access to water-governmental organization, the CPHEEO (Central Public Health and Environmental Engineering Organization ). Yet the country with a total of 1.2 billion people takes the cake in terms of volume of […]

Trash Talk from Bangalore

Everything is garbage until it is segregated. However, despite a never-before crisis staring it in its face, the government doesn’t seem to have realised that there can be answers to what seem to be gigantic problems. As for the one that has pushed Bangalore and of course, surrounding villages like Mandur and Mavallipura over the […]

Municipal Solid Wastes in Qatar

Municipal solid waste management is one of the most serious challenges faced by Qatar. The high rate of population growth, urbanization, migration, industrial growth and economic expansion has led to tremendous increase in solid waste generation in the region. Interestingly, per capita solid waste generation in Qatar is one of the highest worldwide. Solid Waste […]

Sewage Lake of Jeddah

Jeddah, one of the largest cities in Saudi Arabia, has more than three million residents. The estimated water  use is 200 liters per capita per day. Typically, 80% of potable water used  for municipal purposes returns to the environment as wastewater. Since  85% of Jeddah area is not connected to sewerage pipelines, waste water accumulates in […]

Waste to Energy Industry – Trends and Forecasts

Incineration, with energy recovery, is the most common waste-to-energy method employed worldwide. Over the last five years, waste incineration in Europe has generated between an average of 4% to 8% of their countries’ electricity and between an average of 10% to 15% of the continent’s domestic heat. Around 130 million tonnes of municipal solid waste […]
