Think Twice Before Shredding. - Bag Splitter for MSW
© Wasteconsult International (5/2017)
The aim of this document is to provide guidance on the treatment and sorting of Municipal Solid Waste (MSW) using a specific nondestructive method, Bag Splitter and Oversize “Film” Remover, in the early stages of the recovery process, usually just before or after the pre-sort, instead of shredding for certain specific scenarios (waste compostion); weighing the pros and cons from a process that should not only be economically viable but also respectful to the environment without leaving aside an effective sorting which will be interpreted as a greater opportunity for recycling.

Pre-Treatment of Organic Wastes for Wet Digestion Systems – Technology of Komptech
© Arbeitsgemeinschaft Stoffspezifische Abfallbehandlung ASA e.V. (9/2012)
This paper describes how to maximize the methane yield for the wet digestion process and remove impurities from the input material by use of a pre-treatment technology. Komptech is a leading international technology supplier for machines and systems for the mechanical and biological treatment of waste and biomass as a renewable energy source. Seven aims for the pre-treatment of organic wastes to a digestion liquid are described. They can be succeeded by a combination of a shredder, a pulper, a starscreen, a press, a sand trap and a post-shredder. This system is called Pulper Process. The importance of each step is described. The Press Process is shown as an alternative to the Pulper Process.

Comminution – an Essential Component of Waste Treatment

About 20 % of the total quantity of municipal solid waste in Europe is shredded today. This figure is higher – about 40 % – for countries with a high developed waste recovery and recycling system and lower for countries with a developing waste industry.

Effective treatments of household waste using the BHSRotorshredder

The selective comminution of household waste covers a wide range with huge potential. Also a combination of impact crushing and cutting techniques is considered a positive aspect. This will enhance the product quality and increase the recovery rates of an MBT facility.

Recent activities on material cycles of solid waste will drastically change not only quantity but also quality of the waste disposed to landfills. For sustainable waste management, we should adopt technologies for landfilling to expected change of waste quality in near future. In Japan, intermediate treatment on the industrial waste streams have been taken roles in reduction of volume, weight and hazardous nature of waste in order to improve the efficiency of transportation, to save the capacity of landfilling and to avoid the environmental pollution. However, the aim of these processes is moving from treatment to resource recovery because the cost for land disposal has been elevated in some regions.

In Japan, shellfishes are very popular food. Especially, scallop, which is one of the most famous shellfishes and inhabits in the sea around northern Japan area, are caught for eating about 500,000 ton every year. Most of the scallop shells have been treated as waste, and have been piled near fabrication plants (Photo 1-1). To construct sustainable society in northern Japan area, it is an important problem to utilize the scallop shells as the valuable materials. Some effective utilization methods of scallop shells, such as a medicine of the athlete's foot and a wall material for houses, have been tried out, but only a small volume can be used in those methods. We consider that it is necessary to use them in the construction field to consume a large volume of them.

Shredder Practice for Preparation of Nonmetallic Concentrates and Potential for Particle Sorting of these Concentrates

EU directives for end-of-life vehicles (ELVs) require recycling or “recovery” of nonmetallic materials from the ELV. ELVs are collected, de-polluted and stripped of reusable parts at licensed de-pollution facilities (i.e. junkyards).

Extensive Environmental Technologies for Treatment of Municipal Solid Waste and Waste Water
© Wasteconsult International (11/2005)
Mechanical and biological treatment has been established as a concept of handling municipal solid waste. The biological process aims to degrade the organic fraction of the waste to a stabilized product through fermentation and rotting processes. The final maturation produces a depositable residual waste.
