Environment

What are the noise emissions?
Noise is limited by the fitting of silencers to all equipment.

What is the environmental impact of the SPP waste recycling plant?
Practically zero

Is the ambient air quality affected from the plant?
All the air used in the plant is treated so that there is no effect on the ambient air quality.

Is there any water pollution?
All the water used in the plant is treated so that there is no water pollution.

Are there any hazardous gas emissions?
The heat treatment plant operating temperature is 280 degrees C maximum, to limit all  hazardous gas emissions. (Hazard gas emissions usually occur at temperatures over 680 degrees C).

Where should I locate the MSW Recycling Plant?
Locating the plant next to the dump is an ideal solution but it can be located anywhere as pollution and noise is minimal and below recommended levels.

What area is required for the plant?
This depends on the throughput but as a guide here are some facts:
MSW plant requires about 20,000~30,000 square meters
Feed waste about 2000 square meters
Pre-processing about 3000 square
Plastic Pellet plant about 2500 square meters
Paper Pulp plant about 600 square meters
Organic Beads production plant about 1000 square meters
RDF  plant about 600 square meters

Are there any smells given off from the plant?
Utilising Minus Pressure Design treatment -2 MMAQ treats all the air used in the plant, so that there is no effect on the ambient air quality.

How many hectares are necessary for waste fill after processing?
After processing requires about 300 square meters to store the output (demand is more than the supply, so there is no need to have big storage area.)

Does the leak water of the process affect water resource?
All the waste water in the plant is treated so that there is no waste water pollution.
Please reference the file attached.

I want to produce bio-fertilizer from organic beads by mixing additional material can this be done?
Yes, to make bio-fertilizer is no problem. Just add your components to the beads.

Does the plant produce bad Co2?
Burning waste above 500 degrees C produces bad CO2, our design burns about 270~280 degree C and plus we have air treatment, so, no bad CO2 occurs.

How much does it cost to process one ton of waste?
The information on the website states 20 USD/ton is that correct?
In north Taiwan a city like Taipei it costs USD 73/ton, in middle of Taiwan cities it is about USD 37 ~58/ton, China is about USD 11~14/ton and Thailand or Indonesia is about USD 8/ton.

I understand plastic pellets but I am not clear about plastic pallets.
Are Plastic Pallets made from plastic pellets?
Plastic pallets are a very profitable product produced from our plastic pellets, the price of plastic pallets depends on the size and there are more than 200 types of plastic pallet. The current market selling price is about USD 25 ~57/pc.

I see the output of this plant produces RDF. What is RDF and can one use this to build a mini power plant?
RDF means Refuse Derived Fuel, it is 80% efficient compared to coal but we do not recommend you to build a mini power plant because it is not economic.

What products are remaining after the plant has recycled the MSW?
The un-recyclable totals about 3% comprising 2% stone or glass which can be crushed and compacted for use as bedding material in road construction and 1% is ash which can be buried into dumps (landfills)

What about industrial and hospital waste?
Industrial waste is not very economic , so we do not offer a solution, however hospital waste process has more profit and can be considered.

With the SPP plant what happens to other materials? PET, PVC, paper, cardboard, textiles and tires have calorific value and could be burned in cement factories as RDF. Does your plant also sort out these materials too?
PET, PVC, paper, cardboard, textiles and tires have calorific value about 4500~6500 kcal/kg have following solution:
      a.) RDF -- it is used as a coal substitute. ( recycle the heat to dry paper pulp )
      b.) Pyrolysis Fuel oil -- to produce diesel, heavy oil
      c.) Gas -- pyrolysis to gas ( recycle heat to dry paper pulp )
      d.) Cylinder planning -- can produce columns or fence columns
      e.) Glucose -- decomposition to Glucose for agriculture composting.
      f.) General refuse (waste) -- throw away

How does the system separate PE , PVC, PP, and other plastics ? How pure is the pellet produced?
From Pre-Processing separate the waste plastic and those waste plastic has more than 100 different types , for example PE, PP, OPP, PC, PS, PA, ABS, PLA, PAC, POM, PET, PVC, CA, CN, MF, UF, UP ......, plus different type of compound plastic material, totally more than 3000 types of plastic. Those waste plastic is fed into the SPP Main Processing system and according to their gravity, size, absorbent, adhesion, density ratio, settling velocity, flowing rate...etc. different character to select, separate, wash, collect, dump,  dehydration then reach PE, PP compound purify 99.8% plastic material for more information

Are the Landfill pre-processing plants mobile or stationary?
We can design the landfill pre-processing machinery to be mobile for relocation to other landfills.

The Plant

Can one increase the MSW load from 500 tons per day and what is the maximum load capacity?
This depends on the MSW content but the plant maximum load capacity can be increased. For example in China our SPP recycling plant estimated daily processing of MSW is about 800 tons per day (the MSW plastic content is about 8% and paper content about 3%) producing 80 tons of plastic and paper. If you let us know what your MSW content is then we will advise you.

What will be the cost of setting up of extra lines if one has to process 1,000 tons of MSW per day?
This again depends on the MSW content but as a guide the extra cost would be about 70~80%
