DUST CONTROL |
|
Dust consists of tiny solid particles carried by air currents. These articles are formed by a disintegration or fracture process, such as grinding, crushing, or impact. The Mine Safety and Health Administration (MSHA) defines dust as finely divided solids that may become airborne from the original state without any chemical or physical change other than fracture.

LAND FILL - WASTE DISPOSAL - GARBAGE DUMP |
|
Landfill is a waste disposal site for the deposit of the waste onto or into land (i.e., underground), including: internal waste disposal sites (i.e., landfill where a producer of waste is carrying out its own waste disposal at the place of production), and a permanent site (i.e., more than one year), which is used for temporary storage of waste, but excluding: transfer facilities where waste is unloaded in order to permit its preparation for further transport for recovery, treatment or disposal elsewhere, and storage of waste prior to recovery or treatment for a period less than three years as a general rule or storage of waste prior to disposal for period less than one year.

PLASTICS |
|
Plastic covers a range of synthetic or semisynthetic polymerization products. They are composed of organic condensation or addition polymers and may contain other substances to improve performance or economics. There are few natural polymers generally considered to be "plastics". Plastics can be formed into objects or films or fibers. Their name is derived from the fact that many are malleable, having the property of plasticity. Plastics are designed with immense variation in properties such as heat tolerance, hardness, resiliency and many others. Combined with this adaptability, the general uniformity of composition and light weight of plastics ensures their use in almost all industrial segments.
