BioCNG : Fuel of the Future

BioCNG has the abilities and the properties to run any vehicle or motor which can be run on CNG. Every application or motor which uses CNG today, can easily switch to using BioCNG without any hassle. The attributes of BioCNG and CNG are nearly the same in this respect. Thus, BioCNG is the direct and easy replacement of CNG and LPG appliances.

Carbon Clean Solutions


How many times do you wake up to the news of petrol prices hiking? In today’s world with its rampant usage of non-renewable energy resources, this is a major concern for most individuals and organizations. Unfortunately, it doesn’t just stop at petrol and oil resources. Coal and gas are also rapidly running out. As the result effect of the usage of non-renewable resources on the environment is more than alarming, we as the human beings have to accelerate the deployment of more sustainable alternatives.

Although many such sustainable options have been discovered and put to use, the biggest challenge that mankind now faces is the affordability of these options on the whole. However clean a sustainable energy resource be, it must possess the ability of mass production at affordable rates. Only after mass production will an energy resource be considered an actual, viable source.

As of now, we have following…

Animation of a simple telescoping Biogas Digester

The process is very simple — on the first day you put in about 40 kg of animal manure (horse or cow work fastest, but anything will work) and fill up the container with water. Then place the gas collector on top with the valve open so it sinks down into the bottom container, driving out the air. Then close the valve. After about 3 weeks the gas being created inside the container will be flammable.

For this simple animation describing just how simple it is to build your own biogas digester I downloaded Google Sketchup 7 and then used Google 3D Warehouse to download a model of a digester by roilbilad130 called “Biogas untuk limbah dapur” which is Indonesian for “Biogas for Kitchen Garbage”. I changed the food inlet pipe and the fertilizer output pipe to reflect the way they work in the ARTI India systems we have been building in Cairo and Germany and set different sequence animation key frames in Sketchup and did screen capture in Snap Z Pro. Building real digester is about as easy as building a digital one in sketchup — it really is just two plastic barrels, one inverted inside the other, with three pipes — one to get the food in, one to take the liquid fertilizer out and one at the top to deliver the gas to…

Waste-to-Energy in a Dairy Farm

The farm is now turning the extra manure into fuel for its delivery trucks, powering 42 tractor-trailers that make daily runs to raw milk processing plants in Indiana, Kentucky and Tennessee.

Basics of Biogas Technology

All the nine users of the flexible balloon digesters appreciate the technology because of the various advantages it has over using firewood. However, more efforts need to be geared at educating and sensitizing the masses about biogas technology and how to adapt to maintenance demands of the system.

Eat your leftovers

Rather than sitting in a landfill, organic wastes such as food leftovers are put into anaerobic digesters that produce biogas rich in methane. This biogas can be used as fuel for heat and power generation, and the stuff that’s leftover can be used as composting material.

Energy, Technology, & Policy

Americans throw away about 30% of all food produced domestically each year, and since at least 8% of the U.S. energy budget goes towards bringing food to tables across the country, energy waste is closely tied to food waste [1]. In fact, all of that wasted food equates to about 350 million barrels of oil per year [1].

The energy embedded in food waste comes from many sectors of the food industry: production, transportation, storage, and preparation. Since food waste is a cultural problem, it is not likely that it will stop any time soon. A better solution to waste prevention could be to take advantage of the energy potential of food in our landfills. Rather than sitting in a landfill, organic wastes such as food leftovers are put into anaerobic digesters that produce biogas rich in methane [2]. This biogas can be used as fuel for heat and power…

Urban Batch Anaerobic Biodigester

Open Biotecture

In recent days, the Open Biotecture team has been working to develop a portable bio-digester for urban area.

There is an increasing demand for organic waste management in Kathmandu, and some residents have asked us about cost-effective solutions. Currently, the residents of Kathmandu dispose their organic waste in the streets or pay for door-to-door waste collection services. For the latter, the monthly cost ranges anywhere between 200-500 NPR.

Is Portable Anaerobic Bio-digester a good idea?

Open Biotecture investigated existing solutions for treating organic waste in urban areas. The first consideration was given to aerobic composting, however, the process only produces fertiliser as an output. Also, prejudice regarding bad smells emanating from compost bins was considered a strong disincentive to make composting a valued solution.

Instead, we looked at the possibility of creating portable anaerobic biodigesters to process the waste while producing a certain amount of biogas. To simplify the process…

Biogas Initiatives in Bangladesh

Bangladesh Economy

By Dr Aynal Haque

RAJSHAHI, June 10 (BSS)- Low-cost biogas, an alternative fuel for cooking, is increasingly getting popular among the people at different rural areas even in outskirts of the metropolis for the last couple of years.

Biogas is not only used as fuel for cooking foods but the slurry, main effluent of the biogas plant, is also being used as organic fertiliser in the farming fields for boosting its production and in the ponds as fish meal.

The people, who never thought of having gas for cooking rice in their remote areas, are now regularly using for their domestic purposes like civic life. Currently, more than 400 rural families are using biogas instead of firewood to cook foods and to boost farm and fish production.

The Premtaly and some of its adjacent localities under Godagari Upazila has been identified as biogas village, local sources said.

Most of the…

Fuelcell power using Biogas

Clean Energy and Water Technologies

Fuel cell technology is emerging as a base-load power generation technology as well as back-up power for intermittent renewable energy such as solar and wind, substituting conventional storage batteries. However, Fuelcell requires a Fuel in the form of Hydrogen of high purity. The advantage of Fuel cell is, its high electrical efficiency compared to conventional fossil fuel power generation technology, using Carnot cycle. Fuel cell is an electro-chemical device like a battery and generates power using electro-chemical redox reaction silently with no gaseous emission, unlike engines and turbines with combustion, rotary movements and gaseous emissions. The fuel Hydrogen can be generated using a renewable energy sources such as solar and wind as described in my previous articles, “Solar Hydrogen for cleaner future” dated 4 July 2012, and “Renewable Hydrogen for remote power supply “dated 28 June 2012.

Alternatively, Hydrogen can also be generated using biomass through Biogas. Biogas…
