1 IWR Integrated Waste Recycling Integrated System for treatment and recycling of Municipal Solid Waste 1

2 1. Introduction IWR is an integrated system, realised by different Italian companies, manufacturers of specific equipments for the treatment and valorisation of waste, which offer all their skills, experience, know how and support in the site realisation. The IWR system is a multipurpose plant for the treatment of waste with eco compatible processes and innovative solutions for the reduction of gas emission and lifestyle which have low environmental impact. 2

3 The treatment of waste is a very important problem that every country in the world has to face. The project propose a highly technologic and completely environmental friendly solution to all the organizations which have to face, today, the management problem of MSW. How to treat the waste and where to place it? Reusable raw material should be extracted from the waste (the so called secondary raw materials)? Could it be better to proceed in extracting energy with biological methods and/or by means of incineration? 3

4 Incineration is the easiest way to treat the garbage but it is not the answer to environmental problems. The last experiences say that the best ways to treat the waste are: reduction reusing recycling Waste that can be recycled and reused must be recycled and reused. Waste which cannot be recycled and reused must be employed in energy production. Solutions which propose physical treatment of the waste with mechanical cold treatment,, such as washing, sectioning, granulation, etc., are able to recuperate materials to be re introduced in the productive cycle, and at the same time reduce the quantity of waste going to landfill. 4

5 2. Project We have two aims: Clean technology Saving resources Environmental compatibility of the production cycles Construction of an environmental platform for the integrated treatment of the waste (at present prevalently sent to landfill or to the incinerator). Consider all the treatment of urban waste coming both from differentiated and undifferentiated collection, to obtain secondary raw material and clean energy. The plant solves the problems of a community with a waste production up to 3000 ton/day, without burning. It allows to recycle material up to 80 90% of the input waste and only a 10 20% residual go to landfill. It is able to produce energy both to be used by the plant itself and for outside sale (to provide energy to families, industrial areas, municipal common areas, etc.) The plants will be fitted with biological deodorization and all the operations will not produce polluting emissions. It is a turnkey plant, which includes civil works, offices, hangars, weighing machines, etc. 5

11 3. The Plant An integrated management of waste must foresee, as a strategic and priority action, the recuperation of materials from waste and the recuperation of energy from non recyclable residues. The project includes the following treatment lines: Undifferentiated MSW treatment with separation of dump fraction and RDF production (MSW) Treatment of discarded tires and of non chlorinated rubber for the production of rubber granule (various dimensions) and recovered steel and textile (rubber) Treatment of ferrous material including automobiles with automatic separation and recovery of various types of materials (ferrous material) Treatment of fridges, electric appliances and computers, etc., recovering gas and selecting different types of materials (WEEE) Energy production line 11

12 The recuperated fractions must be pre selected and treated with procedures that make them acceptable to the industrial market. The dry fraction of the MSW, by means of different treatments, is used to produce a fuel with very high caloric power without polluting materials, therefore highly ecological. Quality control will support the productive procedures. The plant can be projected and realized in different ways, both for quality and/or quantity of product. 12

The indicative management cost for the waste treatment can change from 15 to 35 Euro/ton, in accordance with the country standards and values and following the investment capacity of the client. The civil works of the IWR platform will be realized in co operation with local companies.
