COMPOST INDUSTRY SUPPLY CHAIN – SHARING THE RESPONSIBILITY
© IWWG International Waste Working Group (10/2007)
The basic concept was to offer residents from all participating councils the opportunity to purchase and easily access bulk quantities of recycled organic compost or mulch product. The product was sourced from five processors of municipal organics at a special discount price for a period of three months to coincide with spring sustainable gardening activities that were planned by member councils. The processor’s products are prepared through natural biological processing of garden waste that is collected from households as part of their council’s collection services. The process, in accordance with Australian Standards for composting takes a number of months and turns garden wastes into quality compost or mulch products.

ANAEROBIC DIGESTION OF SEAWEED WASTE FOR BIOGAS
© IWWG International Waste Working Group (10/2007)
Recently, global warming has become one of the most serious problems all over the world. As a means of solution to the problem, so much attention has been paid to biomass energy. There is so much seaweed waste in Japan, because Japan is an island country. Though seaweeds are very popular materials for food in Japan, seaweed waste has not been used effectively.

BIOLOGICAL HYDROGEN AND METHANE POTENTIAL FROM SWEET SORGHUM RESIDUES
© IWWG International Waste Working Group (10/2007)
The production of methane through the anaerobic digestion of waste water, biomass and putrescible materials, is becoming increasingly less common. Following the growing interest in hydrogen as an energy vehicle, in recent years considerable efforts aimed at identifying “clean” methods and technologies for the production of hydrogen, have been made by the international scientific community.

COMPARISON OF THE ENERGY RECOVERY AND USAGE OF COMPOST FROM GREEN WASTE: WHAT IS THE IMPACT ON PRIMARY RESOURCES?
© IWWG International Waste Working Group (10/2007)
According to §2 and §3 of the Biomass Regulation (2001), the use of green waste (from yards and parks) for power generation is allowed. The generated electricity is subject to the regulations of EEG (regulation for renewable energy), which means a monetary support of 4 – 7 € Cent/kWh. The aim of the governmental promotion is to substitute primary resources by using renewable primary products - particularly to generate a positive effect on the greenhouse gas situation with regard to power generation. Unlike energy recovery, material recovery of green waste is currently not supported in Germany. (Session A7: Composting (I))

Composting of Septic Sludge

As a way of comparing three methods of aeration commonly used in composting, three piles were built using septic sludge and green waste as bulking agent mixed in a volumetric ratio 1:1. Key Words: Biological Treatment, Septic Sludge, Aeration Systems, Carbon content, Green Waste

Inhibition of the apple scab pathogen Venturia inaequalis and the grapewine downy mildew pathogen Plasmopara viticola by extracts of green waste compost
© European Compost Network ECN e.V. (9/2006)
SUMMARY: Extracts of green waste compost have been shown to inhibit plant diseases. In this study, the factors influencing the mechanism of inhibition of apple scab (Venturia inaequalis) and grapevine downy mildew (Plasmopara viticola) were studied. Extracts were prepared from samples of 30 composts from commercial composting plants. Composts were extracted with 1:2 or 1:5 water for 2 or 7 days. Extracts were applied to seedling of apple and grapevine.

Comparison between the composting of green wastes with and without degradable/biodegradable plastics

SUMMARY: An assessment of the composting potential of green wastes (G) only and composting of green wastes with biodegradable plastic (GBIO) and degradable plastic (GDEG) were carried out a lagged two-compartments compost reactor.
