Utility firm, E.ON Denmark, has opened a 300,000 tonne per year Grøngas Vraa organic waste to biogas anaerobic digestion facility.

The company said that the 115 million crown ($17.5 million) facility will produce biomethane from manure and organic wastes and is directly connected to the Danish gas network.

The new biogas plant in Vrå will process 300,000 tonnes of biomass annually, of which approximately 250,000 tonnes is expected to be manure that would otherwise have ended up as untreated on fields.

“When we open the taps for the new biogas plant today, we make it easier to convert manure and food scraps to green energy,” commented Tore Harritshøj, adm. director of E.ON Denmark.

He added that the plant will also reduce Denmark’s CO2 emissions by approximately 25,000 tonnes annually.

The biogas plant, which is the size of 12 football fields, is expected to supply the Danish gas grid with approximately 9 million. cubic meters of biomethane. This corresponds to the annual consumption of 4300 cars or 250 buses if they were running on biogas or the gas consumption of 6500 homes.

E.ON noted that there is still a long way to meet Denmark’s policy objectives of converting 50% of the country’s manure into biogas by 2020. With Grøngas online and several new plants  due for completion in 2016 it said that barely 15% of Danish manure is now used for biogas production.

The company said that the Grøngas Vraa employs approximately 10 people.



Agricultural & Mining Tyres to be Recycled into Diesel & Carbon in Western Australia

Perth, Australia based Tytec Recycling is to open a facility that will turn difficult to recycle off the road (OTR) tyres used in applications such mining and agriculture into energy.

Perth, Australia based Tytec Recycling is to open a facility that will turn difficult to recycle off the road (OTR) tyres used in applications such mining and agriculture into energy.

According to the company the plant will use Edison Award-winning technology from Green Distillation Technologies Corporation (GDTC) – a one-step process claimed to convert OTR tyres into high-quality steel, diesel oil and carbon.

Tytec Recycling added that holds an exclusive global technology license for the Destructive Distillation process for OTR and agricultural tyres,

“We’ve been working on a way to efficiently recycle OTR tyres for the past nine years,” explained Brett Fennell, chairman of Tytec Recycling. “Tytec Recycling is collaborating with GDTC to establish an environmentally friendly way to turn old earthmoving tyres into a renewable energy source.”

Tytec Recycling said that used OTR tyres are buried under mining dumps or stacked in EPA-approved areas around mine sites.

However, according to Fennel “there are plenty of ways to break down tyres but none of them are effective for OTR tyres”.

The company explained that most tyre recycling requires up to six steps, including removing the steel beading from tyres, cutting the tyres into small pieces, then shredding or grinding the tyre cuttings.

The final step in the recycling preparation is to perform magnetic sorting to remove any remaining steel for crumb rubber sales. Crumb rubber is commonly used in athletic surfaces, playgrounds and equestrian footings. However, the larger the tyre, the more costly, maintenance intensive and difficult each step becomes.

According to Tytec Recycling , in order to extract oil and carbon from old tyres, an additional process is required using pyrolysis reactors.

“The Destructive Distillation process used by Tytec Recycling allows a whole OTR tyre to be recycled in a single step,” said Fennell. “We’re using continuous heating technology that’s incredibly energy efficient and results in extremely low emissions.”


“Our reactors operate at a much lower temperature and pressure, providing the added advantage of being safer for system operators and reducing the wear and tear on the plant,” he continued.

The result of the distillation process is said to be reclaimed steel, carbon and diesel of saleable quality. All emissions were claimed meet or exceed EPA, European Environment Agency (EEA) and the Australian Department of Environment Regulation (DER) standards and approvals.

“We’re currently on track to begin OTR recycling in June 2016 and will open our purpose-built recycling center in Perth in January 2017, then Queensland soon after,” said Fennell.

Tytec Recycling added that is will attend MINExpo 2016 in Las Vegas this September to showcase the process and explore potential opportunities to expand the company to other locations around the globe.

Harvest Power Sells 6 MW Anaerobic Digestion Biogas Plant in Ontario

StormFisher Environmental has acquired the London Energy Garden, an anaerobic digester which processes organic waste from southwestern Ontario into biogas and natural fertilisers, from Harvest Ontario Partners – a part of Waltham, Massachusetts based AD developer, Harvest Power.

In Ontario, Canada StormFisher Environmental has acquired the London Energy Garden, an anaerobic digester which processes organic waste from southwestern Ontario into biogas and natural fertilisers, from Harvest Ontario Partners – a part of Waltham, Massachusetts based AD developer, Harvest Power.
The facility, which was developed by Harvest Power, turns organic materials such as food scraps, food production residuals, fats oils and grease, and other discarded organic waste from food processors, retailers and food retail outlets into biogas which is used to generate electricity, as well as fertilisers.

StormFisher Environmental is majority owned and operated by StormFisher, Ltd, a company said to have deep Ontario market knowledge and biogas experience. Harvest Power is a minority owner in StormFisher Environmental.

The facility started operations in spring 2013, has a capacity: 70,000 tonnes per year and generates approximately 6 MW combined heat and power as well as 5200 tonnes of granular fertiliser.

“We are excited to invest new capital and enhance operations at the London Energy Garden,” commented Chris Guillon, vice president of StormFisher Environmental. “These developments open up even more opportunities to serve the organic waste processing needs of the region.”

According to Chris Kasper, CEO of Harvest Power, the facility is in good hands. He added, “Their team was involved in the original design of the site, so it’s fitting to see their involvement come full circle,” he commented.


Israeli Domestic Biogas Kit Hits Crowd-Fund Target in 24hrs

Israeli Domestic Biogas Kit Hits Crowd-Fund Target in 24hrs

An Israeli crowd-funding project to produce a domestic scale biogas digester able to produce enough gas for two hours cooking per day has reached its $100,000 goal on its first day.


An Israeli crowd-funding project to produce a domestic scale biogas digester able to produce enough gas for two hours cooking per day has reached its $100,000 goal on its first day.
In an effort to provide safe and efficient energy to both rural and urban homes, Tel Aviv based HomeBiogasLTD said that it has created a self-assembled biogas system that turns kitchen waste and livestock manure into usable cooking gas and liquid fertiliser.

Optimised for on and off grid urban and rural families, the system is claimed to produce clean cooking gas for three meals and 10 liters of clean natural  liquid fertiliser per day.

According to the developer, as an outdoor biological system HomeBiogas kits are easy to transport and fast to set up, user friendly, and able to significantly reducing dangerous greenhouse gas emissions and pollutants entering our groundwater. The company claimed that using one system could offset a car’s annual carbon emissions.

The system, which has been CE certified for safety, has also been tested and approved for safety and health by the Israeli Ministry Of Environmental Protection and the Ministry of Energy and Infrastructure.

Reduced indoor air pollution
According to HomeBiogas the system also has many health and productivity benefits for families in rural areas. It noted the 2012 WHO Report which found that some 4.3 million women and children die every year from indoor air pollution due to smoke of open cooking fires.

It said that cooking and heating with HomeBiogas reduces deaths and respiratory diseases of women and children as it eliminates the need to use open fires.

The system was also said to saves labour too as families do not need to spend hours collecting and carrying heavy firewood loads every day.

“Our goal at HomeBiogas is to make this system available to everyone, whether you live in a rural area or are an urbanite with a modern kitchen,” said Oshik Efrati, CEO of HomeBiogas.”

“Our system eliminates waste, makes clean gas, and puts an end to breathing in cooking smoke. If everyone owned a HomeBiogas unit, our world would be much cleaner, safer, and greener,” Efrati added.

The company said that so far over 150 units have been in operation in undeveloped communities for over a year and it has been involved with a number of international organisations during this development stage. A video looking at one such project with the Arava Institute for Environmental Studies can be viewed below.

HomeBiogas has now launched a 30 day Indiegogo campaign where contributors can receive discounts on the first retail models to hit the market. The campaign can be found HERE

Converting Olive Mash into Bio Cash

Converting Olive Mash into Bio Cash

January 27, 2015

An experimental system to create heat and power with waste from olive oil processing is up-and-running in Spain. Carina Lagergren, a researcher from Sweden’s KTH Royal Institute of Technology, says the system shows a promising way forward for reducing environmental damage and converting organic waste to energy.

Fuel cell technology was the main attraction for the first-ever visit by a U.S. president to KTH in 2013, and one of the projects presented to President Barack Obama at the university was a process to convert waste from olive oil production to energy for fuel cells.

The project reached its conclusion toward the end of 2014, and today a small-scale prototype system is fully-operational in an olive oil production facility operated by cooperative of San Isidro de Loja, Granada. The electricity it produces is used to help power the plant.

“I remember the President was very curious,” recalls Carina Lagergren, the research leader in applied electrochemistry who presented the project concept to Obama. “He asked, ‘If my friend — a farmer — wants to buy this system to produce electricity from waste on his farm, is it worth it?’ And, I told him it’s not, for the moment, because it’s such a new thing. You cannot buy this and expect that you can save a lot of money.”

“But in the future we hope it will,” she says.

It is currently a 1-kW system, and the project partners — which included PowerCell Sweden AB — are planning to apply for funding to scale the operation up to create 200-kW systems, or enough to supply 50 percent of the processing plant’s energy needs, she says.

“But for this project, the most important thing was finding a solution for all of the toxic waste left over from olive oil production” she says.

Converting the waste to heat and power is a three-part process, beginning with a digester tank that breaks the material down and releases bio gas, comprised of methane, carbon dioxide and sulfur compounds, to a reformer. The reformer converts the bio gas into carbon dioxide and hydrogen, which can then be converted in the fuel cells. When oxygen is introduced in the cell, it mixes with the hydrogen and CO2 to create heat and electricity.

The process depletes the toxicity of the waste and what’s left can safely be transferred to landfill.

“The idea behind the project is to show that it is possible to connect these processes together — starting with olive oil waste — and end up with electrical energy,” she says.

Doing so is a much more sustainable alternative to the current process. After olives are milled and their oil is drawn, the waste containing pesticides and toxic organic compounds is dumped into sludge pits, where it introduces toxins to the surrounding environment.

So PowerCell, KTH and others joined forces to find a better way. For this project PowerCell called on KTH to analyze the influence of impurities of the biogas on their fuel cells.

“We fed the cells with the contaminants that are found in the fuel from the olive oil, or from the environment where the fuel cells  operate, such as hydrogen sulfide and ammonia” Lagergren says.

The KTH researchers also looked into how the impurities affect the fuel cells. “Is it the electrode that suffers, or the electrolyte or the platinum itself, the carbon or the polymer?” she explains.

Lagergren says the answers will help the company define steps for cleaning the gas, and it also provides knowledge of the specifications of the fuel cells for those who are working with the technology.

While the technology is still costly for converting olive mash into cash, fuel cells in general offer a promising alternative source of electrical energy. Molten carbonate cells, for example, already are used for very large systems.

On KTH’s end, Lagergren says the work toward a better fuel cell continues with a focus on bringing down the cost and increasing the efficiency. She is also involved in a project, with Lund and Chalmers universities, to find alternatives to the precious metals that are used as catalysts today in many kinds fuel cells.

“There are other ways to decrease the cost, such as work with the electrolytes. We try to do small improvements with the different components,” she says.

Palm oil waste to energy plant to generate 2.3 MW in Indonesia

Industrial wastewater company ADI Systems Asia Pacific has been commissioned by cleaning product company Wings Corp to design, construct and install a waste to energy plant at its palm oil mill in Jorong, South Kalimantan, Indonesia.

The plant will be built by PT Gawi Makmur Kalimantan to turn fermented Palm Oil Mill Effluent (POME) into a biogas for use in a gas engine. This will produce electrical power to be used by the mill, replacing diesel generators.

The anaerobic system facilitates efficient mixing between sludge and the feedstock, and separates the hydraulic and solids residence times to maximise biogas production and solids breakdown.

In addition to biogas, the reactor generates a liquid effluent and a higher solids waste sludge, which can be irrigated onto farm land as a nutrient supplement, or further treated with aerobic polishing to achieve higher quality final effluent parameters.

Biological commissioning is expected to begin in February 2016 with the plant producing sufficient biogas to supply 2.3 MW of electrical power by May 2016.

Bakery waste to carbo-load bioethanol production in Sweden

A plant that turns leftover biowaste from local bakeries into five million litres of advanced bioethanol has been integrated at an existing oil refinery in Gothenburg, Sweden.

Delivered to North European Bio Tech Oy (NEB), the first Etanolix plant from Finnish energy company St1 will process feedstocks such as biowaste and process residue from local bakeries and bread from shops that is past its sell-by date into ethanol for transport fuel.

The ethanol plant has been integrated into the St1 oil refinery in Gothenburg, with staff also operating the Etanolix plant.

The Etanolix process has been developed as part of an EU funded LIFE+ Project and produces ethanol from biowastes. The steps in the figure above can be described as follows:

  1. Raw-material from the food industry is collected and transported to the refinery
  2. The ethanol plant produces both an 85% ethanol and a by-product called stillage. The stillage can be used as animal feed or the production of biogas
  3. The 85% ethanol is then dehydrated to approximately 100% ethanol
  4. After a quality check the ethanol product is pumped to the refinery storage tanks and then blended to finished product according to specification
  5. Delivery of the gasoline from the refinery to terminals and retail sites.

The Finnish investor of the new Gothenburg ethanol plant, NEB, is an associated company of SOK Corporation and St1.

The production capacity of the plant will be leased to North European Oil Trade Oy (NEOT), sister company to NEB.

The Gothenburg project has been selected for inclusion in the Life+ programme of the European Commission, which provides funding for projects for instance on energy, the climate, environmental management, industry and production, waste management and environmental policy.

In Finland, St1 has delivered four Etanolix plants and one Bionolix plant that produces ethanol from biowaste from shops and households. The first Cellunolix plant using sawdust as a feedstock, will begin production in Kajaani, Finland next year.
