Lead Smelter The Ultimate Solution Some hazardouse slag abrasives may be treated with additives which buffers the acid to pass leachate test (TCLP).
Some cement kilns will process waste but concern of dust/debris if not properly handled as hazardous waste. Lead remains present even if in cement. Recycling of waste to smelter for reuse is ideal solution for DOT. The lead smelter recycler requires iron (fe) as flux, thus steel/iron/lead paint chips are an ideal smelter feed. No down stream lead liability if waste is manufactured into new batteries.
Lead waste becomes a resource rather than liability.

Attention: Mr. Michael Lerner
The Economical Way to Protect the Environment.
Contractor and Industry Shortcuts will cost us dearly for years to come!
The environmental laws are not being equitably enforced. Sand and coal slag blasting is still the accepted practice in many structural steel repainting operations throughout the United States under the trumped up excuse that open blasting with dusty one use abrasive is necessary to remain competitive. Virtually all states still tolerate open blasting. State and Federal authorities still have not mandated total containment or the use of recyclable non-dusting metallic abrasives for blast cleaning in spite of proven environmental and economic advantages to recyclable metallic abrasives. The State of California is reputed to be tough on environmental issues, yet it has a mandated procedure that unwittingly approves dusty, mineral abrasive which often contains excessive quantities of restricted elements under the so called "Qualified Products List" (QPL) for open blast cleaning!
The only way to protect both workers and the environment is to pass legislation requiring the following points to be incorporated, (and monitored after award), in all future bid document specifications:
Steel structure owners should: Protect the environment (minimize liability), provide safer working conditions for employees, preserve the structure, and complete the work in a cost effective manner.
|Coal Slag||Abrasive blasting using non-recyclable coal slag results in suffocating dust and thousands of tons of worthless, potentially hazardous blast debris. This hazardous debris must be recovered and then wasted, filling up scarce landfill space.
Recyclable metallic abrasive cleans faster then coal slag. Virtually no dust is generated and the metallic abrasive can be recovered and cleaned using automated blast recycling equipment for countless reuses.
|Garnet||While garnet can be reused three to five times, each additional use reduces productivity. Plus, garnet blasting creates a lot of dust. It is very expensive and waste recovery and disposal remains an issue.
Why fill our scarce landfills with unnecessary blast waste and cause thousands of unnecessary trucks on the highways?
Water jetting only removes the paint. The mill scale remains and the rust will return before the paint can be applied. The equipment for water jetting is extremely expensive and productivity is poor. Water jetting creates a disposal problem with thousands of gallons of contaminated water.
Metallic abrasive blast cleaning is twice as fast as water jetting. It removes the mill scale and imparts a profile in one step. Water jetting does neither.
Overcoating, or encapsulation of old lead-based paint, is bad science. Adding more paint that has a short life will only contribute to the amount of hazardous waste that must be removed later. In addition, there is the risk that structural defects will be covered over, leading to catastrophic failure of the structure. Overcoating is not lead abatement. It is a high cost, deferred maintenance program that creates additional hazardous waste and passes added costs to future administrations.
The Federal Government's Transportation Research Board (TRB) survey of 36 agencies involved in 4136 bridge rehabilitation projects proves that overcoating failed. Overcoating systems are more costly than total removal. Total removal of rust, mill scale, and paint is the acknowledged good painting practice for dealing with lead based paint on bridges.
