Bleaching mechanical pulp is not a major cause for environmental concern since most of the organic material is retained in the pulp, and the chemicals used hydrogen peroxide and sodium dithionite produce benign byproducts water and, eventually, sodium sulfaterespectively. However, the bleaching of chemical pulps has the potential to cause significant environmental damage, primarily through the release of organic materials into waterways. Pulp mills are almost always located near large bodies of water because they require substantial quantities of water for their processes.
Pacific Ag Seeks Additional Cellulosic Residual for Abengoa Ethanol Plant The Hugoton, Kansas, operation of Oregon based Pacific Ag, LLC is looking for more wheat straw, which along with other ingredients, can be used to produce cellulosic ethanol, a biofuel produced from wood, grasses, or the inedible parts Nordic pulp and paper research plants.
Doug Werner, harvest manager at Pacific Ag: We are contracted by Abengoa, the company that is building the ethanol plant at Hugoton, and we go out and Nordic pulp and paper research to the farmers, and then we go out and swath or shred the cornstalks or wheat stubble and then bail it and then haul it in to be used at that ethanol plant.
This plant is using the wheat straw, corn stalks and milo stalks.
According to a press release from Pacific Ag, the company provides residue management programs not only to harvest the residue for ethanol production, but also to promote long-term crop performance for area farmers.
ON UK has announced that its Blackburn Meadows biomass facility in Sheffield has generated electricity and synchronized with the local distribution network for the first time. Blackburn Meadows is now E.
The 30MW renewable energy plant will convert locally sourced recycled waste wood into electricity, helping to reduce the impact energy generation has on the environment. The plant will displace the emissions of around 80, tonnes of carbon dioxide every year.
Work began on Blackburn Meadows in and since then, around 3, people have been involved in the construction process, including local contractors, helping to bring new jobs and investment to the area. The plant will convert Canadian agricultural products long term goal: Comments to the draft document are due by July 25, Celtic Renewables has already proved the concept of producing biobutanol from draff, the sugar-rich kernels of barley which are soaked in water to facilitate the fermentation process necessary for whisky production, and pot ale, the yeasty liquid that is heated during distillation.
The company will spend the next few months seeking to replicate work done in its Scottish laboratory at an industrial scale. Conversion of discarded pre-consumer food into energy, fuels, and other commodities should be preceded by recovery and redistribution of as much of the food materials as are still wholesome and safe.
Understanding the factors that contribute to disposal of perfectly edible food is a complex and global challenge. The scientific report details how "date labeling" food is resulting in global waste of safely edible food. In an effort to better understand the impact of date labeling on the entire food supply chain, IFT partnered in a broad collaborative assessment to support assessment of the problem.
Thirty-two projects were selected to receive funding from over proposals.
Ten awards were for establishment of new Centers, with the majority of funding dedicated to on-going efforts. Of these, four awards will support advanced aspects of waste and biomass conversion: Vega recently announced it has entered into a Joint Venture to build and operate a manufacturing plant in Allandale, South Carolina to produce Bio-Coal.
Low-Btu biogas sufficient for the GasBox is also often produced at wastewater treatment plants and on farms. The GasBox is already commercially deployed at several locations in Sweden in collaboration with the Swedish Energy Agency and at the Yggeset waste disposal park in Norway.
Energy produced by the GasBox is being used to power equipment and to heat and electrify buildings; the company estimated return on investment ROI in as little as three to five years.
During endurance tests, all the operating parameters initially set in the contract for the TOD were met or exceeded, except the average power output which remains below original expectations.
Europlasma notes that the reasons for the low electrical output are now identified and solutions are known: The proposed plant will use dewatered sewage sludge, FOG fats, oils and greasesseptage waste, and green waste as possible fuel feedstocks from its internal operations.
Locally produced RDF, biomass, and other fuel feedstocks may be available; however, these are not controlled by the ECUA and proposing developers will need to independently secure contingent feedstock supply contracts. The pre-qualification phase of the selection process was completed last winter, and three successful developers have been invited to submit proposals for this stage of the solicitation: The three shortlisted facility developers have until September 18, to submit proposals.
The system uses pyrolysis, a thermochemical decomposition process using high temperatures and an absence of oxygen to destroy all non-recyclable waste. The Smart program is always open and offers funding to single, UK-based, small and medium-sized enterprises SMEs to engage in research and development projects from which successful new products, processes, and services could emerge.
Smart is currently accepting applications for the Round 2. Those eligible to apply include non-profit corporations; Pennsylvania schools, colleges and universities; any Pennsylvania municipality, and public or private corporations, partnerships, limited liability companies, associations and other legal business entities.
Potential applicants are encouraged to participate in a related webinar, scheduled for June 24 from p. To register for the webinar, complete the online grant application or learn more about PEDA, visit www. Pennsylvania Energy Development Authority. Applications are due by 4 p.
The plant will be capable of producing GWh of heat equivalent to the annual consumption of heat for 25, homes and GWh of electricity per year, consuming abouttonnes of municipal solid waste a year.
The production capacity of the new plant will be MW of electricity and MW of heat.
The plant will primarily use wood chips as fuel, but can use the full range of solid biomass. Due to the changed fuel mix, the new biofuel-based plant has both direct and indirect environmental benefits, as the CO2 emissions will decrease.

Bleaching of wood pulp is the chemical processing of wood pulp to lighten its color and whiten the pulp. The primary product of wood pulp is paper, for which whiteness (similar to, but distinct from brightness) is an important characteristic.
These processes and chemistry are also applicable to the bleaching of non-wood pulps, such as those made . Nordic Pulp and Paper Research Journal | Citations: 1, | Read articles with impact on ResearchGate, the professional network for scientists.
