Aerobic Composting of Livestock Manure by Thermophile and Enzymes

In Japan, 84 million tons of livestock manure are generated annually, Concerns about manure’s adverse impact on the environment, including its offensive odor, pollution of water, and greenhouse-gas generation, have made livestock farmers recognize the need to find ways to properly process and effectively utilize manure. Livestock farmers are prohibited from open-air piling and burying of the discharges. They must properly dispose of it in accordance with „Act on the Appropriate Treatment and Promotion of Utilization of Livestock Manure”, which took effect in 2004 in Japan. This act substantially recommend aerobic composting.

To cope with livestock discharge problems, we developed an environmentally-friendly, quick-composting material „resQ1)" series.

One of the products, „Buta-resQ" is a deodorizer with a bacterium that effectively decomposes malodorous materials such as short-chain fatty acids. This bacterium, Bacillus sp. strain TAB7 is a thermophilic, cellulolytic, facultative anaerobic bacterium that degrades propionic acid, butyric acid, and pentanoic acid in both aerobic and anaerobic conditions. In the germination experiment of Japanese mustard spinach (Brassica rapa var. perviridis), the germination rate of the compost with use of "Buta-resQ" is higher than that of the control (compost with no use of "Buta-resQ").

Synergien durch Anlagenkombinationen auf Biogasanlagen
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2018)
Getrennt gesammelte Bioabfälle sind ein wertvoller Sekundärrohstoff und sollten möglichst energetisch als auch stofflich verwertet werden. Fehlwürfe bei der Sammlung bedingen sowohl eine aufwändige als auch kostenintensive Abfallaufbereitung in Hinblick auf Investitions- und Instandhaltungskosten vor der Vergärung bzw. nach der Kompostierung.

Umsetzung der Umstellung einer Kompostieranlage aus (Vorschalt-) Vergärung

Bereits seit Jahrhunderten werden für die Abfallwirtschaft vielfältige Technologien und Strategien entwickelt und zunehmend auch kommerziell umgesetzt, um die organischen Abfallfraktionen sowohl umweltverträglich als auch ökonomisch sinnvoll zu behandeln und möglichst auch zu verwerten.

The APECS-biomass model
© Wasteconsult international (5/2015)
Organic wastes in all their different shapes and compositions have gained significant commercial, political and academic interest during the last decade. The main driver for this development is the widely accepted consideration of organic wastes as valuable resources rather than problematic or worthless stuff. With the aim to turn the economy from its fossil basis into a bio-economy with presumably higher resource efficiency and less negative or even positive climate impact, governments in many countries have startedto support the use of waste biomass in many ways including subsidies.

Compost-like material or thermal valorization – impact on MBT Plant economics and environmental aspects – Case studies in Portugal and UK
© Wasteconsult international (5/2015)
The paper focuses on the utilisation of the solid product from the biological Treatment stages of three MBT Plants which treat the organic fraction of MSW by means of wet mechanical pre-treatment units followed by anaerobic digestion. The experiences of two MBT Plants in Portugal (CVO Valorlis and CVO Suldouro) which produce compost-like material are contrasted with the experiences at the MBT Bredbury Parkway (UK) which, by drying the digested solids, produces a RDF with low calorific value for further use in thermal valorisation. The impact of these two different approaches on the operating costs for the treatment of the digested solids as well as the environmental aspects for both valorization paths is discussed.

Post-treatment of Composting Leachate by Photocatalytic Process
© Wasteconsult international (5/2015)
In this study the capability of UV-ZnO photocatalytic process as a post Treatment method for composting leachate was examined at laboratory scale and in batch mode. The effect of some factors such as initial pH, oxidant concentration, light intensity and reaction time on the removal of organic load and color of leachate were investigated. Biological pre-treated leachate samples were collected from the effluent of leachate treatment facility of a composting plant in north of Iran. A Plexiglas column with 110 mm inner diameter and 300 mm height were used to conduct experiments. UVC lamps with different power levels in the range of 8-40W at the centre of the column were used as the source of irradiation. Based on the results of experiments, after 180 minutes of Radiation with 32W UVC lamps in pH 11 and in the presence of 1g.L-1 of slurry ZnO, maximum COD and color removal were achieved to be 57% and 67%, respectively.
