When I'm speaking about pasty fuels it means mainly fuels made out of industrial waste and fuels made of hazardous waste. Not working, oh yes it works. I'm CEO of SID group but in my heart I'm an engineer so I participated a lot in the development of the systems I'm presenting you now.

SID has it's headquarters in the Western part of Switzerland close to Neuchatel. It's manufacturing waste treatment system since 1972. The main products are big size reduction machines that means rotary shears and hook shredders but in the mean time we are also manufacturing related products, mixers for raised and also pumps for difficult pumpable materials.

We have also in the meantime subsidiaries in Germany, France, China and India. Production, manufacturing is done in Switzerland, Germany and China. One of the specialties of SID are SMP kiln feeding systems. What means SMP? SMP means systems which has a treading, mixing and pumping step.

The idea is to produce out of different waste of homogeneous slurry only having about hand size foreign objects in the slurry. So how does it look like? We have the possibility to put in bulk waste from a usual bunker. Packed waste. The waste goes in via interlocking door system. The reason is we want to isolate the system from the environment.

Afterwards we have the shredding step, then the mixing step and the pumping step. What you see here is an installation set we delivered to Japan. This installation was not installed in a cement plant but it was installed in a hazardous waste incinerator, but the system are basically very comparable, anyway any system is a bit different because we always have to do some adoptions.

The delivered in the meantime 15 systems in total, SMP systems, shredding mix and pumping systems, four of this 15 system for cement kilns, three in the last two years. So for cement kilns it's a relative or for cement process it's relative new system, but what you see also see here is one of the main activity of SID is related to hazardous waste.

That means we deliver more than hundreds of plants for hazardous waste shredding including a souting[sp?] systems that means a separation system, pumping systems and interlocking door system, and about in the last 20 years more than 500 systems in general for waste treatment or the mainly shredding systems that means our specialties are our very big shredders that means big shredders that can treat more than up to 200 tones per hour.

Hazardous waste, what does it mean? Hazardous waste is waste that cannot be treated in a conventional incineration plant and that cannot be disposed in a normal land field. It's normally characterized that it has a low ignition point, it's very reactive, it's corrosive and it's toxic.

So why using such a material which is more difficult to treat than other materials? First, it is the material which has usually the highest gate fees that means you get highest prices to accept it. Usually holds a good calorific value and for some products it is an effective destruction especially some hydrocarbures due to the high temperatures you have in cement process, it can
