http://waste-management-world.com/a/900-tpd-waste-to-energy-contract-for-everbright-in-china
Hong Kong based waste to energy developer, China Everbright International (HKSE: 00257), has won the bid for the 900 tonne per day Shandong Zoucheng waste to energy project in China.
The company said that it has now signed a concession agreement with the City Appearance & Environmental Health Bureau of Zoucheng for the Zoucheng waste to energy project which will be constructed on a BOT (Build‐Operate‐Transfer) basis with a concession period of 30 years.
The plant has a designed daily household waste processing capacity of 900 tonnes and will be constructed in two phases. Phase I has a daily household waste processing capacity of 600 tonnes.
Everbright said that the project represents a total investment of approximately RMB353 million ($55.5 million) and that gas emissions will fully comply with the Euro 2000 Standard. It is expected to generate approximately 70,000 GWh of electricity annually.
The company added that Zoucheng is a national historical and cultural attraction and one of China’s top tourist cities with sites such as Mencius Temple pictured above. Given its continued economic and social development and its increasing amount of waste generated, the Zoucheng government launched the waste‐to‐energy project to facilitate the harmless treatment, reduction and reuse of household waste.
The Zoucheng Project is the first waste to energy facility to be developed in the city.

German micro power generation technology developer, ENTRADE, has launched a biowaste powered tri-generation high temperature gasification system for providing power, heat and cooling.
German micro power generation technology developer, ENTRADE, has launched a biowaste powered tri-generation high temperature gasification system for providing power, heat and cooling.
The mass produced, sub £200,000 system is claimed to be the world’s smallest combined cooling, heat and power (CCHP) unit fuelled by regional available biomass waste.
The technology is said to be based on a high-temperature, carbon-neutral and highly efficient gasification process.
It uses solid biomass waste to generates up to 30 kW of electricity, 60 kW of heating and/or cooling up to 30 kW of cooling, said to beenough for 22 American single family homes, a small production facility or even a village in developing countries.
ENTRADE said that one E3 unit is a turnkey solution small enough to be easily transportable on a pickup truck.
So far over 100 types of solid waste are certified for use in the system, including nut shells and other regional biomass.
“Here it is: The world’s smallest tri-generation power plant fuelled by waste, that will have a huge impact on the everyday-life of millions of people without any access to clean energy,” said ’ Julien Uhlig, ENTRADE’s CEO.
“The strong demand out of the world market is a hint to be sure that it’s an idea whose time has come,” he continued. “The E3 is ready to go into mass production.”
The company plans to produce up to 45 units per month with a target of 600 units in 2016.

Biomethane from Organic Wastes Could Quadruple by 2021
Biomethane Availability and Usability
Utilization of green energy has progressed tremendously over the last few decades. However, many renewable and environmentally friendly sources of energy pose a challenge when it comes to availability or usability, or both. Solar energy for instance can be successfully harnessed only in regions which have a high amount of sunshine, wind turbines can be used to generate electricity only in areas with sufficient amount and power of the wind, etc. which makes their usability largely limited to regions which have ideal geographical or/and weather conditions. Biomethane production, on the other hand, has no such limits. On the contrary, methane which is derived from organic matter and is equivalent to fossil fuel derived methane when it comes to both chemical structure and usability can be produced just about everywhere.
Biomethane is produced by anaerobic digestion (bacterial breakdown in absence of oxygen) of organic matter such as organic household waste, dead animal and plant material, manure, slurry, sewage and other organic materials which are found in large quantities on literally every step all over the world. The usability of anaerobic digestion of organic matter for power generation was discovered many years ago, however, biogas plants were not economically feasible due to relatively low cost of natural gas and other fossil fuels just a few years ago. But due to highly unstable fossil fuel prices, fears that peak oil has already been reached and the potentially catastrophic effects of global warming, the interest in sustainable and environmentally friendly sources of energy has increased dramatically in the recent years. Renewable energy, however, accounts for a small part of the total global energy output.
This is partly related to the fact that efficient technology for power generation from alternative sources of energy has been developed only recently but it is partly also related to limited availability/accessibility to green sources of energy. But the percentage of global energy that is generated from renewable and environmentally friendly sources of energy is steadily rising also thanks to biomethane. It provides a stable and efficient source of energy to regions which do not have the ability to generate power from solar energy, wind power, etc. Biomethane production requires only collection of organic waste material and construction of biogas plants which are very simple in technological terms and relatively inexpensive in comparison to other green power generation facilities of comparable power output.
Usability is another great advantage of biomethane besides availability. Since it is identical to fossil fuel derived methane, it can be used for space heating, water heating, cooking, etc. but it can also be used for electricity generation and if compressed, as fuel for vehicles. Burning biomethane produces the same amount of carbon dioxide and other greenhouse gases as burning the conventional natural gas. But in contrary to the latter, biomethane does not increase the greenhouse effect and global warming because its utilization produces the same quantity of greenhouse gases as if organic matter would be left to decompose in nature.
Jan Allen Plans to Turn Everyone’s Food Waste into Renewable Energy with This Machine
http://electronics360.globalspec.com/article/5849/jan-allen-plans-to-turn-everyone-s-food-waste-into-renewable-energy-with-this-machine
Jan Allen has been involved in design, construction and operation of organics facilities for over 25 years. Now, he is the president of Impact Bioenergy, a company developing a machine that can convert organic waste materials into energy and fertilizer with zero waste. The machine has the capability to converting 25 tons of waste into energy each year.
Allen tells us about the machine, referred to as the “HORSE”, as well as the company’s goal of making communities more self-sufficient and granting individuals the opportunity to create renewable energy right on their property.
Electronics360: Can you tell me a little bit about your background? Do you come from a technical background since your work is generally focused around an electricity-producing machine?
Jan Allen: I have been involved in design, construction and operation of organics facilities since 1989. The aerobic (composting) facilities I designed have diverted over 10 million tons or organics from landfilling and the anaerobic systems produce 10 MW of renewable energy. I am the registered inventor of six U.S. Patents for composting, digestion and biofiltration. I’m a professional civil engineer and was educated at Purdue University in Indiana. I’m more of a microbiologist and nuts and bolts guy than an electrical guy.
Electronics360: Where did you come up with the concept for the HORSE?
Jan Allen: When I was in college, my advisor persuaded me to build three small digesters to convert waste into renewable natural gas. It was an inspiring project. Then much later in my career, I was working for a large firm in Boston that had a mission to build large urban power stations that are fueled by commercial food waste. When I was there, I was impressed at how many inquiries we received for smaller systems. My company did not want to bother with small projects. No one else in the industry did either.
So that was the main reason for starting Impact Bioenergy. There was a need and no one was filling it.
Now there are at least 35 companies selling or developing owner-operator anaerobic digestion technology in North America. Not one of them has scaled down to restaurant, office, campus, or hotel scale. Not one of them has brought the footprint and cost down to the onsite or community scale. It’s not that the technology can’t be scaled—it’s more about conventional wisdom with supersized facilities and long development timelines—on the order of two to 10 years. Conventional wisdom says that small projects take as much effort as big ones, but are not as profitable. These companies just don’t recognize the high cost and risk of permitting and waste transport.
Electronics360: Can you explain the science and technology behind the machine?
Jan Allen: It is a liquid system that uses microbes to mimic a living animal. We call it a HORSE, but it functions like a mechanical cow. The food waste is called feedstock and has to be ground and pureed into a smoothie-like consistency. It is metering into the system in small doses continuously and automatically. The system is maintained at 100 F°, is mixed, is airtight (anaerobic), and is monitored for pH, gas production, liquid level, pressure, etc. A gallon of feedstock takes 30 days to make it through the two stages and then overflows out as digested liquid plant food. There are only four moving parts: a mixer, heating pump, grinder pump and dosing valve. There is a gas manifold and a liquid manifold to manage the system.
Electronics360: How exactly does it generate electricity? How much power can it really produce?
Jan Allen: The machine makes natural gas. The gas is stored in a gas storage vessel until it can be used. To make electricity, the gas is used as a fuel in an engine generator. This is an ideal application for combined heat and power. The machine is rated for a full speed output of 15,000 BTU per hour. There are lots of choices for engine types, CHP systems, electrical efficiencies, etc. In general, making heat or hot water can be 90% to 94% efficient. Making electricity only can be 12% to 40% efficient. Making combined heat and power can be somewhere between these figures.
It will consume 25 tons per year of food scraps, beverages, fat and paper products. It can create 5,400 gallons per year of liquid fertilizer and up to 37 MW-hrs of raw energy. As renewable gas, that’s 125 Million BTU per year (4.3 MW-hrs of this energy is electrical output).
This is what that is equivalent to:
Electronics360: How do you envision the HORSE working in a community?
Jan Allen: The vision is to become more self-sufficient and to make renewable energy on your property and fertilize your own or a nearby garden or farm to grow food and flowers. The HORSE is both a sustainability and society game changer. It’s all about the quadruple bottom line: people, planet, profit and progress. There are 700,000 restaurants and 4,000 college campuses in North America. Each one should have their own HORSE. Just imagine the sustainable energy revolution for islands, resorts, zoos, museums, schools, parks, convention centers, farmer’s markets, music venues, apartments and corporate and municipal campuses as they turn food scraps into energy. This is just the beginning.
The HORSE will eradicate curbside garbage pickup and the carbon emissions associated with long distance trucking. It will create a whole new shared carbon-negative transportation model for local use: less trucking plus no landfilling plus renewable energy! Its combined benefit is disruptive and huge; It’s decentralized—it’s portable—it’s affordable. Imagine a technology that can divert waste and create energy off-grid. Imagine eliminating the organic waste from your trashcan. Imagine making it into two valuable new resources that you can personally or commercially use.
Electronics360: What are Impact Bioenergy’s goals at this point?
Jan Allen: To establish a few key partnerships and get these machines on the ground and operating. Everyone wants to see one working. We need reference facilities.
Electronics360: Where do you see yourself and the company in 10 years?
Jan Allen: We see a network of community supporting biocycling groups sharing information with each other. Impact Bioenergy is the core technology provider, designer, builder and supplier of the HORSE digester. CSB is the service end of a strategic partnering program that helps remove barriers to market this transformational technology in different locations. It is a partnering program between businesses such as breweries, restaurants, markets, urban farmers, and gardeners. What is Biocycling? Biocycling is the recycling of organic materials. In the context of our project, this term describes the process of taking organic wastes such as food scraps and converting it into liquid fertilizer and energy that can once more be used directly on the farm at which these food resources were originally produced. We like to say…Farm to fork to fertilizer and fuel, and back to the farm again.
Electronics360: Is there any other technology currently being developed behind the scenes?
Jan Allen: We are working on upgrading the biogas to CNG vehicle fuel. Back to the Future may be fictional, but the machine that converts food scraps into energy is here, because we just built it. This is a living machine that eats food scraps and makes energy and plant food using microbes with zero waste.
Electronics360: What do you find most challenging about being part of a company based on technology geared toward improving the environment?
Jan Allen: Right now the company needs operating systems on the ground so people can see the technology in action in an urban environment. To that end, a recent crowdfunding project has successfully reached its goal just this month to build a reference facility in Seattle. Remarkably, about 30% of the money pledged came from individuals in New York City.
Biggest lessons learned on the business end are:
that being disruptive means some existing stakeholders will not embrace your good idea
that triple bottom line decisions that account for environmental, social values in dollars is very rare indeed
that accountants rule the day on payback period, return on investment, cost savings, etc. Remarkably this technology does offer what the accountants want.
Biggest lessons learned on the social and cultural end are:
The idea of converting waste into energy and organic matter with zero waste really resonates. Impact Bioenergy has no payroll, but three full time workers, seven part time workers, and a constant stream of job seekers and volunteers
Overall there were 16,000 video starts on the crowdfunding page
People in 68 countries clicked into the crowdfunding page and video
The biggest lessons on the technology/environment end are:
This technology is no more complicated that having a real horse or a large aquarium. The machine wants to be fed lots of small meals, doesn’t like to be cold, and sometimes needs antacids
Visual art and odor control are essential. They are integrated into the design so it fits in the urban setting
The big win here is eliminating trucks hauling waste away and hauling food into the city. That is two groups of trucks! Trucking is a huge cost and environmental burden to the city in air quality, greenhouse gases, congestion, noise, fuel use and export of resources and jobs away from the community.
Using a HORSE eliminates the odor, flies, rats, seagulls and leakage associated with the traditional dumpster.

Water Utility Inaugurates Waste-to-Energy Project
The District of Columbia’s water utility, DC Water, has unveiled a $470 million waste-to-energy project that will produce a net 10 megawatts (MW) of electricity from the wastewater treatment process. The result is energy that powers approximately one-third of the Blue Plains treatment plant’s energy requirements.
The project began in 2011 and brought in new technology to North America such as the CAMBI thermal hydrolysis process. Thermal hydrolysis uses high heat and pressure to “pressure cook” the solids left over at the end of the wastewater treatment process. This weakens the solids’ cell walls and the structure between cells to make the energy more easily accessible to organisms in the next stage of the process, anaerobic digestion. The methane these organisms produce is captured and fed to three turbines to produce electricity. Steam is also captured and directed back into the process.
Finally, the solids at the end of the process are a cleaner Class A biosolids product that DC Water uses as a compost-like material. Biosolids products are currently being used around the District for urban gardens and green infrastructure projects. DC Water is also working to bring a compost-like product to market.
The project was based on more than a decade of research before bringing these facilities online. The project also received a 2012 Grand Prize in Planning Award from the American Academy of Environmental Engineers & Scientists, a 2012 Global Honor Award in Planning from the International Water Association and a WERF Excellence in Innovation Award was presented in 2011.

Government Grant Awarded to Fuel UK Towards Sustainable Future
http://www.environmental-expert.com/news/government-grant-awarded-to-fuel-uk-towards-sustainable-future-599664
A consortium of UK companies led by advanced waste to energy and fuels company, Advanced Plasma Power (APP), has today been awarded £11m in government funding to develop and build the first-ever plant of its kind which will turn waste from local homes and businesses into a sustainable fuel to power heavy goods vehicles.
The grant has been awarded to APP and its partners National Grid, clean energy firm Progressive Energy, and CNG Services, a company which provides gas for use in vehicles, as part of a Department for Transport (DfT) programme to develop and commercialise the technologies required to decarbonise the transport sector.
The new APP plant in Swindon will be the first of its kind in the world and take residual waste – the UK’s largest sustainable source of biomass – and convert it into compressed biomethane, using APP’s pioneering Gasplasma® technology and will produce enough fuel for 75 heavy goods vehicles, equivalent to all of the buses operating in Swindon.
Biomethane can be used interchangeably with natural gas in heavy goods vehicles and is significantly less carbon-intensive and less polluting than diesel. It has the potential to cut transport carbon emissions by up to 96 per cent.
Construction of the plant will begin in 2016 and the consortium has already found local customers for the product and suppliers for the feedstock. The post-recycling residual waste will be provided by a local source, and the gas produced will be used by local haulage company, Howard Tenens, and consortium partner CNG Services.
The use of gas as a transport fuel is growing. John Lewis already uses it for some heavy goods vehicles, whilst some bus services operated in Reading and Sunderland also run on the fuel.
The consortium has been working together over the last five years on a project to produce a renewable natural gas made from waste that can be pumped into the UK’s gas pipeline network which provides an excellent means of distributing the fuel to where it is needed.
Transport Minister Andrew Jones announced news of the grant as part of £25 million awarded to winners of the Government’s Advanced Biofuels Demonstration Competition.
Rolf Stein, CEO of Advanced Plasma Power, said:
“APP is delighted to have been selected in this competition by the DfT. It recognises our position at the very forefront of environmental and technical innovation in the UK. The grant also highlights the important role our technology can play in producing clean biofuels from waste on a local basis, so as to help reduce the greenhouse gas emissions from both the waste management as well as transport sectors without the requirement to give over large swathes of land to growing energy crops. From an economic, environmental and social perspective it presents a real triple win.
Our state-of-the-art process can unlock the enormous value of residual waste as a resource and provides a cost-effective means of converting such waste to fuels such as bio-methane. Our expectation is that this plant will lead the way to a new generation of ultimate recycling facilities both in the UK and around the world.”
Transport Minister, Andrew Jones said:
“This is a great example of our commitment to innovative transport technology and supporting jobs and growth.
Biofuels have an important role to play in keeping Britain moving forward in a sustainable and environmentally-friendly way. This £25 million is not only a vital investment in technology that will help secure a greener future but will also support the creation of thousands of jobs.
Advanced biofuels have the potential to save at least 60% of the greenhouse gas emissions from the equivalent fossil fuel. Swindon’s successful bid shows how the government is investing in transport and making better, clean journeys.”
David Parkin, Director of Network Strategy at National Grid, said:
“National Grid provides a gas network across much of the country and is proud to be part of this pioneering Department for Transport (DfT) programme to decarbonise transport.
We believe that the use of renewable gas as a fuel in the transport sector will play a significant role in reducing greenhouse gas emissions in the future. The benefits of using household waste to create fuel for HGVs and busses is clear; lower emissions, quieter engine noise and favourable fuel prices.
“Green gas generation has been a technology that has seen particularly rapid growth in the last few years and this pioneering project is just one of the innovative renewable energy projects National Grid is involved with, working alongside a number of technical partners across the UK.”
Chris Manson-Whitton, Director of Progressive Energy, said:
“We are tremendously excited about this true waste-to-wheels project which exemplifies the circular economy. The award by the DfT is testament to the vision and dedication of the consortium. It is a springboard to exploiting our indigenous residual waste resource to provide a secure and low cost transport fuel for our truck and bus fleets.”
John Baldwin, Managing Director of CNG Services, said:
‘A high proportion of waste is not suitable for anaerobic digestion, the APP gasification pathway means that this waste will be able to be used as a vehicle fuel, with sufficient resource for all UK trucks to move from diesel to Bio-CNG. As such, this project is hugely significant in the journey to decarbonise transport by 2050.’
