Doosan Enpure is one of the 4 R&D centres of excellence of worldwide Doosan Water Business Group specialising in waste treatment and renewable energy technologies. Doosan actively invests in its waste and renewable energy related research and development activities to create and launch needs-driven technologies that will introduce innovative solutions to the worldwide waste and renewable energy sector.
With over 400 UK anaerobic digestion plants in operation, and a similar number in the Planning process, reducing energy subsidies and feedstock cost increases or reducing gate fees lead the sector to look ever closer for Process improvement and optimisation.
Successful laboratory scale trials, overseen by Birmingham City University, have demonstrated that Doosan’s sonix process can significantly increase anaerobic digestion biogas yields from various feedstocks. So successful were the results that Doosan committed to a >£1 million R&D project to build and operate a full size agricultural AD plant sonix system. This is now in full operation progressing towards completion of a robust six month trial demonstrating the benefits of the process.
Sonix applies ultrasonic sound energy to feedstocks to break open cellulosic barriers enabling the anaerobic digestion biology more ready access to digestible content. The process is fully containerised with plug and play design meaning the new plant is operating within days of arrival on site. Available at various throughput sizes the sonix process can be retro fitted to an existing plant or included in new build facilities, giving the developer high returns and payback in well under five years.
Commenting on the project, the Waste & Energy Business Development Manager for Doosan Enpure, Kevin Clarke, said: “The objective of our sonix project is to expand upon our promising laboratory scale results by demonstrating on a full scale operational plant the biogas yield improvements, and reduced cake disposal quantities which together will offer existing and proposed plant operators significant investment return benefits.”
An ultra modern waste-to-energy plant near Chin, Alberta, will be built using Highmark`s patented IMUS technology. It will be a multi-feedstock system, capable of digesting potatoes, cattle manure and other nearby waste while killing off pathogens. The whole community will benefit from the Perry family`s innovation and forward-thinking stewardship of their century-old farming operation."Grow. Live. Be the Change -- Grow the energy circle!"

Demonstration project with university researchers involves cleaning biogas to develop renewable energy options for farmers.
A MINNESOTA dairy - the Haubenschild family farm near Princeton - is making history by becoming the first demonstration project in the world to run a hydrogen fuel cell from the biogas captured from cows. For five years, as reported in BioCycle, the Haubenschilds have been operating an anaerobic digester to process manure from their cows (now numbering...
Pennsylvania Power & Light, Alliant Energy, Wisconsin Electric and Portland General Electric are some utilities that are plugging into anaerobic digestion projects.
AT the October, 2001 BioCycle conference on “Renewable Energy from Organics Recycling,” the director of the Iowa Energy Center, Floyd Barwig, pointed out that the possibility of separating the United States from Middle East oil politics “takes on much greater meaning. ... A heightened need for security can become another driver of an energy...
The Kemwater Recycling Process – KREPRO for treatment of sewage sludge is based on a completely new separation technology, which uses existing knowledge in an innovative way. It reduces both the organic and inorganic content of the sludge. The organic content is re-duced by about 30% and the inorganic about 70% if digested sludge is treated. All metals and salts are dissolved; the remaining undissolved inorganics are mainly silicates like sand and grit.
In constast, most sludge treatment technologies used today...
CEDAR RAPIDS — with active support from the Iowa Department of Natural Resources (DNR) — is optimistic about its new strategy to expand organics recycling. Under the leadership of executive director Dave Hogan, the Bluestem Solid Waste Agency, which serves the Cedar Rapids region, is presently composting 118,000 tons/year of yard trimmings and paper/pharmaceutical sludges. But Hogan is convinced that more diversion of municipal solid waste can be achieved, significantly reducing future landfill needs. The...
Abstract
In the present paper some results of a study carried out on the anaerobic digestion of Sugar Mill Filter Cake (SMFC), use of natural zeolite to intensify the biogas production, as well as the use of the digestion mud, in biofertilizer quality are presented. The method allows obtaining increments of biogas production in the range of 20-40 %. It was shown that application of the mud containing the added doses of stimulator, far from causing any affectation, facilitates to obtain a significant improvement...
Abstract
All European countries undertake great strengths in biological treatment of organic waste. There are countries with fully implemented organic waste policy, some with plans for and countries where no policy has been prepared. The trend goes versus separate collection of the organics from gardens, parks and households and to treatment via composting. Quality assurance of compost plays a central role. Around 400 composting plants in Europe take part in large quality management systems. The important...
Within the last decade, implementation of state and federal regulations and other local codes have changed biosolids processing in Florida. Previously, biosolids stabilization varied greatly among the state’s 3,500 to 4,000 wastewater treatment facilities. Public and privately owned wastewater treatment facilities were required to stabilize their biosolids to a minimum Class C standard for land application, with most facilities using aerobic or anaerobic digestion. Requirements for septage solids stabilization,...
The need to upgrade dairy waste management practices to overcome pollution problems is leading more farmers to seek solutions with anaerobic digestion technology. Two recent examples of this trend are underway at California sites.
The Cal Poly Dairy is located adjacent to the California Polytechnic State University campus in San Luis Obispo. The dairy milks 180 cows with a total population of over 350 animals, including heifers and calves. Most of the herd is housed in freestall barns. About 90 percent of the...
Compared to countries like Germany and Denmark, the United States and Canada have a long way to go in creating the fundamental policy incentives and regulatory mandates that will encourage market development for anaerobic digestion (AD). Someone recently asked me how many years it would take to deploy AD systems on farms in North America that are large enough to economically use them. Given today’s slow deployment rate, the only answer I could give was several hundred years. This is largely because the U.S. has...
Executive Summary
In 1995, the nation’s largest industrial users of toxic chemicals released 2.2 billion pounds of toxic chemicals into the environment (U.S. EPA, 1995 Toxic Release Inventory) and spent billions of dollars managing pollution control technology systems to prevent that number from being higher. If one were to add in the purchase price of the raw materials that eventually escaped as 2.2 billion pounds of chemical waste (instead of product), the price tag grows even larger. Many companies have made...
The Environmental Protection Agency (EPA) is making available to the public a study containing information relating to its Proposed Rule addressing the management of mercury-containing lamps under the Resource Conservation and Recovery Act Subtitle C hazardous waste management system published in the Federal Register on July 27, 1994, 59 FR 39288. The study consists of an electronic model and report that provides an assessment of mercury emissions from the management of mercury-containing lamps under different...
Introduction For many years, efforts to promote energy efficiency and pollution prevention (P2) traveled on parallel paths. Most energy efficiency advocates considered only the energy savings aspects of their projects and most proponents of P2 did not include energy on their list of sources of pollution. More recently, the two groups promoting energy efficiency and P2 have begun to realize the synergies of working together. Energy efficiency projects often have non-energy P2 benefits and P2 projects often save...
Containment treatments are often performed to prevent, or significantly reduce, the migration of contaminants in soils or ground water. Containment is necessary whenever contaminated materials are to be buried or left in place at a site. In general, containment is performed when extensive subsurface contamination at a site precludes excavation and removal of wastes because of potential hazards, unrealistic cost, or lack of adequate treatment technologies.
Containment treatments offer quick installation times and...
What is chemical dehalogenation? Chemical dehalogenation is a chemical process to remove halogens (usually chlorine) from a chemical contaminant, rendering it less hazardous. Halogens are a class of chemical elements that include chlorine, bromine, iodine, and fluorine. Polychlorinated biphenyls are halogenated compounds that once were used in high voltage electrical transformers because they conducted heat well while being fire resistant and good electrical insulators. In addition, halogenated compounds are used...
