  • Beating treatment to enhance digestibility of fresh grass

    Anaerobic digestion (AD) is one of the most popular biomass conversion technologies. AD can be further divided into four stages: pre–treatment, digestion, gas upgrading and digestate. The main goal of pre–treatment is to improve degradability of the material in order to enhance gas production and anaerobic digester performance. Beating treatment as a new mechanical treatment technique has been ...

  • Biohydrogen production from tequila vinasses using a fixed bed reactor

    In Mexico, the industrial production of tequila leads to the discharge of more than 31.2 million of m3 of vinasse, which causes serious environmental issues because of its acidity, high organic load and the presence of recalcitrant compounds. The aim of this research was to study the feasibility of a fixed bed reactor for the production of biohydrogen by using tequila vinasse as substrate. The ...

  • Kickoff for Biogas - South America Opts for Green Energy Made by WELTEC

    Currently, the world is locked on to the FIFA World Cup in Brazil. Though they have already reached a high technical level as far as football is concerned, the South American countries still have development potential in the fields of biogas technology and renewable energies. In the interview, Aguinaldo Ramalho of the German biogas plant manufacturer WELTEC BIOPOWER talks about the potential, ...

  • Towards a sustainable use of food waste: influence of urea on biogas production potentials of selected fruit wastes in Addis Ababa, Ethiopia

    This study evaluates the influence of adding urea on biogas (methane) production potentials of selected fruit wastes. Using standard methodology, the finding revealed that all the fruit wastes are ideal substrates for biogas production. The ultimate biogas yield on anaerobic digestion of fruit waste feeds, avocado, banana, and mango, are 0.48, 0.57, 0.53 l/g VS without urea supplement and 0.76, ...

  • Assessing the treatment costs and the fertilizing value of the output products in digestate treatment systems

    The objective of this paper was to advance towards finding sustainable solutions to deal with biogas digestate and contribute to faster development of the market for digestate treatment products. The study compares digestate treatment costs through four different treatment plants, estimates the potential fertilizing and humus value (PFHV) of the derived products and allocates the cash flows to ...

  • Anaerobic co-digestion of municipal organic wastes and pre-treatment to enhance biogas production from waste

    Co-digestion and pre-treatment have been recognized as effective, low-cost and commercially viable approaches to reduce anaerobic digestion process limitations and improve biogas yields. In our previous batch-scale study, fat, oil, and grease (FOG) was investigated as a suitable potential co-substrate, and thermo-chemical pre-treatment (TCPT) at pH = 10 and 55 °C improved CH4 ...

  • Allweiler Peristaltic Pumps: an ingenious solution for biogas plants

    Installations and plants used to process biomass for the production of biofuels must be capable of handling difficult conditions. For example, intermediate products in the production of biodiesel exhibit a high level of chemical aggressiveness. Accordingly, pumps, pipe connections, and fittings must be capable of resisting these demanding conditions. In addition, waste products usually contain a ...

  • Effect assessment of temperature on biogas production from bovine rumen and banana (Musa acuminata) stem undergoing anaerobic codigestion

    In this research banana (Musa acuminata) stem waste and bovine rumen were taken to undergo degradation by anaerobic codigestion. The stem and rumen were mixed to obtain four ratios of substrate and three replicates were taken for each. 750 mL bioreactors were used, with a 3 temperature factorial arrangement (25, 35 and 45°C). Initial conditions and final physicochemical parameters were analysed. ...
