1. Dust Suppression Fence Technology: This is also called wind fence, it is usually used for the outdoor storage yard in the mine, harbor or coal stock that could prevent the stock inside from blowing away by the wind. Canadian technology would be more advanced. 2. Belt Sealing Technology: In the mine or some factories, there are lots of belt used for material transfer. While the material is dropping from higher place or from one belt to another, there will be some dust generated. Now we want to find some good technology to achieve better sealing of the belt that require maximum encapsulation, easy maintenance and low cost will be preferred. 3. Small Size Filter Cartridge Technology: The Filter cartridge with compact size and higher efficiency of dust removal. 4. Road Dust Suppressant: Some kinds of chemical or drug that could be sprayed in the road and the function is to suppress the dust into the air. This chemical should be non-toxic, biodegradable, low cost and high efficiency. 5. Water Canon Production Technology: We are looking for some company that have the full set of technology to produce the water canon both in China and Foreign country. 在国内外寻找喷雾炮的全套生产工艺，用于城市空气污染的治理。 6. Laser Detection Technology for Dust Concentration: Using the laser to detect the dust and then the signal could be transferred to get some data of the dust concentration, it should be reliable and quick-response. 7. Dry Fog Technology: We are looking for some technology that could produce ultrafine water droplet of which the diameter is lower than 10 micrometer. 8. VOC Treatment Technology: We are looking for some international leading treatment technology of volatile organic carbons. 9. Garbage Power Generation Technology: Collection of the solid waste and use some methods like incineration, fermentation or other new technology. 10. Car Crush and Recycle Use: The integrated set of equipment or methods that used for waste or useless car crushing and recycling. 11. Mineral Solid Waste and Wastewater Recycle Technology: First is the effective methods to recycle the useful ingredient of the mineral solid waste, second is the high efficient wastewater recycle technology with low cost, like the recommendation of some good flocculent. 12. Ultra High Molecular Weight Polyethylene (UHMWPE): 我们想在国内寻找一种超高分子聚乙烯材料，要求具有较高的耐磨性，可以做成筒状，可以焊接，能做成定制的颜色（或者较深的颜色如深灰色等）
