									   Earth’s Big Rescue
          “A PROPOSAL”
          Business Target

• To restore landfills and its surrounding land
  back to nature by joint business
  participation. The recovered land would
  then be developed at very high profit.
• Automatic pre-screening to separate the
  waste, eliminate pollution.
• To convert waste into plastic pellets and
  pyrolysis oil to produce additional profit.
               Our Advantage
• We have the rights of Beijing waste landfills to
  install and fully develop recycle plants.
• A nearly endless source of waste.
• The continuous demand in the consumption of
  crude oil and its raw materials ensures a very
  long term profit forecast.
• The plastic recovered from the waste after
  washing and recycling has a purity rating above
• Our highly profitable patented* recycling plant
  produces plastic pellets and pyrolysis oil
  continuously. (*China, Taiwan and Japan patent.)
                  Profit Source

• Pyrolysis heavy oil, diesel or plastic pellet sales
• RDF, thermal energy conversion and steam
  sales profit
• The greatest profit will be achieved when the
  landfill sites (Beijing city has 490 in total alone)
  are restored and development.
             Plant Architecture
• One set of landfill automatic pre-processing
  equipment will process 1000 tons of waste daily and
  produces about 90 tons of waste plastic material.
• One set of automatic pyrolysis fuel system will
  process 30 tons of waste plastic daily and output 21
  kiloliter of diesel or 23 kiloliter of heavy oil.
• One set of automatic SPP waste plastic film
  processing equipment and plastic pellet extraction
  facility will process 50 tons of PP,PE plastic film and
  produce 50 tons of plastic pellets daily.
• Land provided by the Government, self-built factory,
  about 6000 square meters land requirement.
Medium and long-term planning

With the population and waste increasing,
the Beijing landfills cannot keep up with
demand and an alternative solution must be
It has been agreed that the second phase
project, landfills and MSW processing at the
same time must start now. If actual demand
increases the plant equipment will be
increased to reverse the trend.

Retrieving Plastic Waste Material and Automatic Continuous Feed

             Pyrolysis Fuel technology and the procedure

According to waste polymeric material research one is required to design the
      equipment in order to convert and reduce the plastic waste product into fuel.
      The plant has ten major
•     Plastic waste breaking process.
•     Preheating Raw materials process.
•     HCL-absorbing process.
•     High temperature burning heating process.
•     Solid alloy thermal ball heating process.
•     Automatic continuously feeding catalytic cracking process.
•     Smoke Purification process.
•     Heat exchanger cooling process.
•     Fractionation refining process.
•     Sludge - Harmless brick processing system.
This equipment has a very low requirement for maintenance - no cleaning or
sorting, and uses an automatic conveyor feeding system - while one side feeds
the raw plastic, the other side is supplying oil and de-slagging.
      Equipment Technique Introduction

• The plant uses rotary drum catalytic pyrolysis technology - the
  shredded recycled waste plastics is fed continuously into the
  cracking furnace to increase thermal efficiency and maximize
  processing power.
• In the preheating stage, the pyrolysis plant process purifies the
  mixed waste plastic PVC material and harmful gases such as HCL
  gas are removed, this in turn protects the equipment from erosion.
  Inside the Pyrolysis plant the gas is fed into catalytic converter then
  cracked, fractionation, cooled and separated. The non-condensable
  gas is purified and supply for the heating process and production
  use, the generated flue gas purify again by the flue gas purification
  system to meet the developed countries’ emission standard.
• The cracking pyrolysis system produces carbide and is fed onto a
  conveyor system to the combustion furnace for combustion and
  removal. The generated harmless ash is automatically collected and
  is environmentally curing.
  The unique advantages of automatic
         pyrolysis equipment

• Automatic continuously feeding, cracking, oil,
  slagging, the whole year without shut down, the
  maximum can be designed to feed 200 tons waste
  plastics per day.
• Waste plastic pyrolysis process will produce acid,
  the equipment can be continuous discharged acid,
  otherwise after condensation will produce
  hydrochloric acid and it will corrode pipeline
• Pyrolysis process, the furnace will not have the glue
  knot, no need to shutdown and clean up.

Waste Plastic Recycling Key Factors
1.Clean water is required
A. Sterilization facilities
              - Protection of the operator (Health and Safety)
B. Pollution substances excluded (e.g. COD, BOD, SS, pulp, slime)
   Causes increased turbidity
       –    Impact: water surface tension, viscosity and water weight
            change ( above 1 )
       –    Materials settling velocity changes (resistance increasing)
            such as PVC, PET, OPS, etc. ( Gravity above 1 plastic film)

 The deterioration of separation between the different plastic film
 materials is caused by these various changes of resistance
The recovery purity can be achieved by maintaining the water
