Hazardous Oil-Bearing Secondary Materials and Recovered Oil from Petroleum Refining Operations — Oil-bearing hazardous secondary materials (i.e., sludges, byproducts, or spent materials) and recovered oil (does not include used oil as defined in 40 CFR 279.1) generated at a petroleum refinery and inserted into the petroleum refining process ...

SMART members can assist with large quantities of textiles materials such as misprinted t-shirts, linen from hospitals, prisons, hotels, etc. If you have large quantities and are looking for a textile recycling partner, contact SMART at 443-640-1050 for more information on how to recycle these items.

The invention relates to a process for the recovery of secondary raw materials containing iron, zinc and lead, preferably steel mill dusts, in a rotary kiln plant which is usually designed for the rolling process and has a basic rolling slag. By reducing the proportion of carbon carriers in the feed, the energy balance of the rolling process is improved on the one hand and the throughput of ...

Secondary drying of these materials relies on the removal of water by molecular diffusion through the glassy frozen matrix and can be a relatively slow process taking 10 to 12 hours. The temperatures used during secondary drying are higher and the pressures lower than for primary drying.

As opposed to primary research, secondary research is fast and easy. It aims at gaining a broader understanding of subject matter. Primary research is an expensive process and consumes a lot of time to collect and analyze data. Secondary research is a quick process as data is already available.

11.4 SECONDARY TREATMENT. The secondary treatment is designed to remove soluble organics from the wastewater. Secondary treatment consists of a biological process and secondary settling is designed to substantially degrade the biological content of the sewage such as are derived from human waste, food waste, soaps and detergent.

Hazardous secondary materials that are released to the environment and are not recovered immediately are discarded. (b) The following factor must be considered in making a determination as to the overall legitimacy of a specific recycling activity. (1) The product of the recycling process does not:

Secondary minerals (e.g., clays, oxides, and hydroxides of iron) can only occur as inherited weathering on dimension stones collected from quarries and used as building materials of low quality. As the weathering of building stones proceeds, gradational changes occur in the physical and mechanical properties of rocks, so weathering is mainly ...

(8) Secondary materials that are reclaimed and returned to the original process or processes in which they were generated where they are reused in the production process provided: (i) Only tank storage is involved, and the entire process through completion of reclamation is closed by being entirely connected with pipes or other comparable ...
