LCA applied to elucidate opportunities for biogas from wastewaters in Colombia
Biogas produced in municipal and industrial wastewater treatment facilities (BWWF) is a resource wasted in several socio-economic contexts. BWWF-based projects are compared against energy projects using conventional electricity or natural gas (NG), following strict economic considerations that usually tip the balance in favour of conventional energy supply. This is because the economic gain ...

Small scale biogas upgrading: Green gas with the DMT Carborex® MS system
Abstract More and more effort is being put in the utilization of bio-solids. Bio-solids can be an important source for useful products like fertilizers and biogas. DMT has been developing biogas treatment plants for over 20 years following the market developments closely. Biogas was first seen as a nuisance at e.g. landfills, creating odor problems and methane emissions. A flare has always ...

The DMT Carborex® MS Small scale biogas upgrading plant
Introduction As we are all aware, fossil fuels are depleting rapidly and the energy consumption is growing. Due to increasing fossil fuel prices other types of fuels become more interesting. Nowadays technology enables us to use renewable fuels in an economically profitable way. An easy technique to produce fuel is the digestion of green waste; sewage sludge, manure and agricultural waste from ...

Winning projects at clean energy awards benefit women
The winning projects of this year's Ashden Awards for sustainable energy, which were announced last month (30 May), have particular benefits for women, organisers say. The projects demonstrate how improved access to clean energy can make women's routine tasks less onerous, and provide women with better opportunities, according to Ashden's communications officer, Carla Jones. The international ...

Case study - Grand Junction Sets the Pace with Colorado’s First Biogas-to-Vehicle Fuel Project at the Persigo Wastewater Plant
The first biogas-to-vehicle fuel project in Colorado converts wastewater-derived biogas mto renewable natural gas (RNG) to fuel city and county fleet vehicles Summary: The Per si go wastewater treatment plant in Grand Junction, Colorado, a city of about 60,000, processes upwards of 8.2 million gallons per day of wastewater in two anaerobic digestion tanks (primary and secondary). The facility ...

Biogas as an option for industrial applications
Biogas is typically burned to produce electricity or used as vehicle fuel. This case study analyses possibilities to utilise biogas directly in industrial applications to replace current fossil raw materials. True industrial cases are analysed by considering economic impacts of using either landfill gas or gas produced from biomass. Utilisation of biogas is economically viable and technically ...

Project - Small Scale Organic Waste to Biogas
With its low cost and innovative solution to treat organic municipal solid waste, Green Elephant empowered municipal corporations and corporates to eliminate all sort of Organic waste in decentralized manner. Under this Green Elephant have provide solutions to treat from 1 tons to 50 tons of organic waste per days with biogas generation upto 1,26,000 Nm3 Per annum. Location: India, UAE, ...

Quantification of leakage in batch biogas assays
Avoiding leaks is essential for accurate measurement of biogas production by batch assays. Here we present a simple method for detecting leaks and correcting results, based on the change in bottle mass during incubation. Three experiments were carried out using pure chemicals, wastewater sludge, and other complex substrates to test and demonstrate the method, and leaks were detected in all ...

Cow’s fueling cars
Biogas upgrading at the Hagelsrum farm Farmers who make biogas from manure are not uncommon, but the Birgersson family on Hagelsrum’s farm goes further than that. With four biogas fueling stations and a fifth one coming up, they are contributing to the circular economy and closing the circle from cow to fuel tank. At the Hagelsrum’s farm just outside the town of Målilla, 650 ...

Case study - Sacramento, California: The first U.S. city to power refuse trucks on renewable natural gas (RNG) made from separated food
California has long been a pioneer in implementing sustainable transportation strategies, and yet again, the State can claim another first-of-its land project in the United States as its own. By collecting and diverting food waste from a local landfill, two Sacramento-area companies, CleanWorld and Atlas Disposal Industries, have opened the Sacramento Biodigester — the first closed-loop ...

Generation using gas-fuelled engines in South Africa – an overview
Most gas engines are Otto cycle spark ignition internal combustion reciprocating engines using natural gas as the primary fuel. Smaller models utilise stochiometric combustion while the larger engines are lean burn engines with pre-chamber ignition systems. The engines are coupled with packaged generator sets, cogeneration and, even, trigeneration units to optimise energy utilisation in the fuel ...
