  • Biomass energy outlook

    Over the last three or four weeks, my newsletter, Burning Bio News, has been oddly extreme. Timothy Searchinger, Princeton University, is churning out more antibiofuel hearsay. Dennis Avery, Hudson Institute, was in the news again putting a counter-spin on climate change. The U.S.EPA released its proposed rule for regulation of Greenhouse Gases (GHG) that includes industrial facilities that emit ...

  • Applying ERP to the biomass supply chain

    Green alternatives to hydrocarbon-based fuels are increasingly derived from recycled waste materials, including paper and packaging materials; residues from other industrial processes, and perhaps most importantly, biomass. Biomass comprises plant waste and plant by-products, and currently represents one of the most exciting avenues of research in the development of alternatives to fossil fuels. ...

  • Woody Biomass as renewable energy source

    In-depth analysis in Minnesota assesses the feasibility and cost-effectiveness of regional biomass generated electricity projects that tap into local feedstocks. The Center for Energy and Environment (CEE) in Minneapolis, Minnesota undertook a multiphase research project to create a framework that communities and legislators can use to determine the feasibility of biomass-generated electricity in ...

  • New technologies for measuring the humidity of biomass

    Methods applicable to a great variety of solid biofuels In recent years, systems have sprung up which use near infrared X-ray (NIR) spectroscopy, radio frequency (RF) and microwave spectroscopy as alternatives to the traditional method of measuring humidity by weight difference in the fuel burner. What these methods have in common is that they can be used for a great variety of solid biofuels, ...

  • Small-scale electricity production from biomass

    NC Service has set up the first plant of this type in Spain Thanks to the BIOCOM Project, Nicolás Correa Service, S.A. has built the first biomass combustion plant that not only produces thermal energy, but also electricity on a small scale (130 gross kWe). The process is based on the combustion of woodchips in a furnace to produce heat that is then transferred to an ORC module, where it ...

  • Flexible Biomass Gasification Technology for Distributed Power Generation

    The ultimate aim of this research and development project is to demonstrate the key technological aspects of the proposed biomass gasification technology for distributed power generation, in order to speed up the commercial update of biomass as a reliable and cheap renewable energy source across Partner countries. Australia will lead this project with the collaboration of Japan, China, India, and ...

  • The Standard For Total Biomass Measurement in Metalworking Fluids

    Metalworking fluids provide a warm and nutrient-rich environment for growth of bacteria and fungus.  Once microbial growth is established it can contribute to the breakdown of the metal working fluid emulsion and consequently its ability to lubricate metallic surfaces.  Microbes also lower the fluid's pH, leading to corrosion of tool parts and staining of wetted metal surfaces.  ...

  • Generating biomass fuel from disaster debris

    Natural disasters create massive amounts of vegetative debris, the majority of which is landfilled or open burned. These environmentally harmful practices are the norm partly out of necessity and convenience, with a focus on clearing material as quickly as possible after a disaster - versus finding outlets for the material including mulch, compost and biomass fuel. The biomass fuel market in ...

  • Solutions for the exploitation of biomass energy in mountain regions

    Using tow-cables to extract and transport biomass to forest paths Many forests are located on mountainous terrain with steep slopes, making their exploitation not economically viable, at least with traditional methods. This can lead to the abandonment of such hilly woodlands, giving rise to rodent infestation or forest fires, with resulting damage to the woods themselves and to surrounding areas. ...

  • Modeling of an IFAS Process with Fungal Biomass Treating Pharmaceutical Wastewater

    The project involved the dynamic modeling of a wastewater treatment plant (WWTP) treating pharmaceutical wastewater. The WWTP uses an integrated fixed-film activated sludge (IFAS) process with suspended carriers for biological treatment. The plant is unique in that it uses both fungal and bacterial IFAS reactors. The fungal biomass has been shown in laboratory testing to degrade a portion of the ...

  • Ratios of microbial biomass estimates to evaluate microbial physiology in soil

    Abstract  Soil microbial biomass data derived from fumigation–extraction (FE), substrate-induced respiration (SIR) and ATP estimations differed significantly and were significantly correlated, which agrees to previous studies. In a second step, the SIR/FE, ATP/FE and SIR/ATP ratios were calculated to evaluate the glucose-responsive and active component of the microbial (active and resting) ...


  • Investigation of long-term operation and biomass activity in a membrane bioreactor system

    The aim of this work was to evaluate the long-term performance of a Membrane Bioreactor (MBR) that operated continuously for 2.5 years and to assess membrane fouling and biomass activity under various operating conditions. Furthermore, a method for the characterisation of influent wastewater was developed based on its separation into various fractions. The MBR system operated at the solids ...

  • Ozonation of endogenous residue and active biomass from a synthetic activated sludge

    Coupling the activated sludge and the ozonation processes is an efficient, although expensive, solution for sludge reduction. A better knowledge of the mechanisms involved in the degradation of various sludge fractions by ozone is needed to optimize the coupled process. The objectives of this study were to determine the biodegradability of ozone-solubilized endogenous residue, the action of ozone ...

  • North American forest biomass helps EU hit 2020 energy targets

    BC Bioenergy Network ("BCBN"), a provincially-funded leader in the growing bioenergy sector in British Columbia and the Wood Pellet Association of Canada ("WPAC"), have released a report that documents Canada's contribution to the EU's renewable energy targets. The study modeled forest carbon dynamics and determined that the production of energy from sustainable solid biomass rapidly mitigates ...

  • Flotation of algae for water reuse and biomass production: role of zeta potential and surfactant to separate algal particles

    The effect of chemical coagulation and biological auto-flocculation relative to zeta potential was examined to compare flotation and sedimentation separation processes for algae harvesting. Experiments revealed that microalgae separation is related to auto-flocculation of Anabaena spp. and requires chemical coagulation for the whole period of microalgae cultivation. In addition, microalgae ...

  • Estimation of the energetic parameters associated with the continuous aerobic biodegradation of phenol by monoculture of Pseudomonas aeruginosa and Pseudomonas fluorescence

    The objective of this study was to estimate and analyse the growth parameters of indigenous monoculture of Pseudomonas aeruginosa and Pseudomonas fluorescence on phenol in an aerobic chemostat culture. The biodegradation data were checked for consistency using carbon and available electron balances and growth parameters were estimated using two forms of growth models: reparameterised Pirt's model ...

  • Identification of α-β unsaturated aldehydes as sources of toxicity to activated sludge biomass in polyester manufacturing wastewater

    Wastewater generated in industrial production processes are often contaminated by hazardous chemicals. Characterization by means of toxicity-directed analysis is useful for identifying which fractions of a waste stream possess the most toxicity. We applied this approach to evaluate toxic components of a polyester manufacturing wastewater. Using the reduction in oxygen uptake rate of activated ...

  • Activities of nitrogen-mineralization enzymes associated with soil aggregate size fractions of three tillage systems

    Nitrogen mineralization occurring near the soil surface of agroecosystems determines the quantity of plant-available N, and soil enzymes produced by microorganisms play significant roles in the N mineralization process. Tillage systems may influence soil microbial communities and N mineralization enzymes through alterations in total soil C and N. Soil aggregates of different sizes provide diverse ...
