Human beings have been dumping waste in water, including the ocean, since before the Agricultural Age. The Industrial Age brought with it new materials to dump, chemical wastes and by-products. Some materials are dumped into rivers and find their way to the ocean by running downstream. Other materials are dumped directly into the ocean from boats. Plastic is a harmful pollutant that does not break down easily in the ocean. Plastic accounts for 90 percent of all floating materials in the ocean.
The U.S. government has implemented the Ocean Dumping Ban Act of 1988 that makes it unlawful for any person to dump or transport for the purpose of dumping, sewage sludge or industrial waste into ocean waters after December 31, 1991 and provides for the payment of special fees for dumping and any penalties incurred by a dumper to be deposited into certain funds for use in finding alternatives to ocean dumping.
Ocean dumping, sewage system, road and field run-off into our waters has become a disaster and is very difficult and time consuming to clean up, but the biggest problem in the ocean is dumped plastics that take a long period of time to break down. Plastics are killing our birds and our sea life because as the plastics break down into microplastics that the birds and fish believe are food. Eating these plastics will eventually clog-up the birds and fish’s digestive system, causing death.
The Ocean contains four large garbage patches, the Western Garbage patch, the Subtropical Coverage Zone, the Eastern Garbage Patch and other Gyres with Marine Debris. With the polluted oceans and water ways being a massive cleanup project, the question I have is when we bring the waste out of these oceans and water ways what are we going to do with it, i.e. landfill it, or incinerate it? We certainly do not have enough landfill space for all the debris. This cleanup project is a herculean task that will take years and the development of multiple new technologies.
The second apocalypse scenario and the one we are going to concentrate on in this article is the fact that hazardous/toxic wastes are materials that are ignitable, reactive, corrosive or toxic to human health. Treatment of hazardous waste is stabilization and solidification, recycling, disposal in isolated areas of landfills, incineration and pyrolysis. The latter two require very high temperatures. The above covers the treatment and/or storage of most hazardous wastes. Please keep in mind that if the hazardous waste cannot be recycled, such as lead and acids from batteries, they are sent to a regulated landfill. The generator or owner who is storing the waste owns it under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), revised as Superfund. CERCLA requires a treatment that permanently and significantly reduces: volume, mobility of hazardous substance and stops toxicity.
One such hazardous material is asbestos. Asbestos lawsuits permeate our courts and have created a multimillion dollar industry for the legal firms. Unfortunately, there are billions of tons of asbestos that will permeate into our environment for century’s to come. 125 million people are exposed to asbestos in the work place each year, around the world someone dies of an asbestos related disease every five minutes and more people die from asbestos illnesses each year then are killed in road accidents. Given all that is known about the deadly dangers of asbestos, the generators/owners keep landfilling it because the price is cheaper than permanently destroying it and removing any future liability.
Climate change has become obvious, causing massive forest fires, droughts, high winds, floods, mudslides, hurricanes and tornadoes. It is only a matter of time before a fluid, hurricane and/or a tornado rips through a landfill cell with toxic waste or asbestos, spreading these toxins for miles. Industry leaders must constantly and consistently seek out or invest in ways to rid our environment of these dangerous toxins.
There are two families of asbestos mineral: Serpentine, which is Chrysotile, and Amphibole—Amosite, Crocidolite, Actinolite, Anthophylite and Actinolite (see Figure 1). There are several destruction technologies that destroy asbestos. Two are high temperature and one is non-thermal. The high temperature processes destroys the asbestos at 2500 degrees F. They are Vitrification and Hearth Oven. They require complicated scrubber systems to limit emissions and a great amount of electrical energy to operate, requiring highly skilled labor to operate these plants. Two other issues are the waste reduction volume is not great and if the treated asbestos is not totally destroyed at the end of the throughput, it must cool down before it can be checked for complete asbestos destruction. If asbestos is found not destroyed in a batch, that batch must be run through the process again. Both of these processes are EPA approved.
The third process, which is a non-thermal process, is EPA approved, simple to operate, does not require high electrical use and is operated by accredited asbestos workers and one lab technician who can read a polarized microscope. This process, unlike the high temperature processes is built mobile, transportable and sized to meet the client’s needs. It also reduces waste volume by 30 to 50 percent; most importantly, asbestos destruction is verified through process, therefore no asbestos leaves the process undestroyed.
All three asbestos destruction processes require shredding of asbestos containing material. Not all asbestos containing material can be put through a shredder to be treated asbestos free. The thermal processes leaves an asbestos containing material untreated like pipe or any other materials that cannot be put through the shredder, because they will do harm to the shredder. Whereas the non- thermal process proprietary chemical formulas was granted EPA approval to wash any asbestos containing material asbestos free that could not be shredded.
The non-thermal process is first shredded through the primary enclosed shredder and then screw conveyed in an enclosed screw conveyor into a finer secondary shredder for further size reduction up to a ¼ inch (note: both shredders are equipped with aerating water spray nozzles to keep the asbestos wet at all times). From the secondary shredder, the asbestos containing material is slowly fed by enclosed screw conveyor into the specially designed primary mixer that has been pre-charged with the proprietary conversion chemical. The primary mixer is equipped with an inverter and amperage meter to properly operate the speed of the mixer. The asbestos is kept in an aqueous solution at all times. The primary mixer has a special blade tolerance to avoid jamming, because of the inconsistencies of the asbestos containing material.
The primary mixer is started at a slow inverter speed while the allowable amount of asbestos is fed into the primary mixer. Once the asbestos containing material is 95 to 98 percent destroyed in the primary mixer, it is pumped into the secondary mixer. When the asbestos containing material is verified to be completely destroyed, it is pumped into a settling tank to allow the solids to settle out and the proprietary chemicals to be siphoned off and reused. The remaining solids are pumped into a specially built cement mixer for neutralization and recycling.
Because no asbestos containing material leaves the non-thermal process before it is verified non-asbestos, the non-thermal process is time saving, electrical cost saving, environmentally friendly and the verification that no asbestos has left the process before destroyed. It meets the EPA required final testing for conformation of asbestos destruction by Transmission Electron Microscope (TEM) as required by 40 CFR 61.155—Standard for Operations that Convert Asbestos-Containing Waste Material into Non—Asbestos (Asbestos—Free) Material.
Making the Effort
As human beings, every day we are becoming more and more aware of the damage we have done and are doing to our environment by not recycling and by not practicing conservation. I will leave you with this thought from a Wall Street Journal Salt and Pepper cartoon from 16 years ago: The scene is of a father sitting on a couch and his son standing in front of him. The father is looking at the son’s report card with great despair and disappointment, obviously expressing his opinion about the report card to the son. The son could not have given a better answer to his father for not receiving better grades. His answer: “If your generation doesn't learn to save the planet, it won’t matter if my generation can’t read or write.
Sixteen years later has become truer and truer. It is up to all who have the power to develop technologies and/ or implement waste solving technologies to make the effort no matter what the price, because we cannot afford the cost.
