Hazardous materials may originate from our homes or from manufacturing industries. The common types of waste that are encountered within the home setting include automotive waste such as oil, batteries, rust removers and gas. Another category is that of chemicals and cleaning agents that includes photo chemicals, household bleaches, paints and pesticides. Others include medical waste such as used needles, syringes and expired drugs. There are a number of vital things on hazardous waste disposal Edmonton residents need to know.
A material will be considered hazardous if it has one or more of several characteristics. These include toxicity, ability to corrode, explosive and combustible potential and so on. Chemicals with any of these properties are usually identified by a label. The disposal process should always be based on the instructions from the manufacturer.
The traditional approach of getting rid of these materials was by burying them in ordinary landfills. This option fell out of favor when it was noted that some of these materials would seep into the ground and contaminate water sources. Countermeasures against this have to be put in place as a matter of regulation. This may involve, for instance, having a barrier at the bottom of the pit. Various forms of treatment may also be required before burial.
The other option that one may consider is recycling of some materials. There are a good number of these materials that can be reused for the same purpose or put into alternative uses as long as due caution is exercised. Industrial fuels and other flammable materials are among those that are easiest to put back to use. Others include lead acid car batteries and electronic circuit boards. The ash from heavy metals can be used to fill pavements and to help get rid of other pollutants.
Portland cement manufacture is another process that is quite useful in improving the physical characteristics of various types of hazardous materials. It helps to solidify and stabilize these materials and reduces the levels of toxicity. Other components have to be added to the sludge to increase strength and make it safer. They include phosphates, sulfur and pH adjustment agents among others.
The destruction of these products may be re-engineered to produce energy. This is what happens in many cement kilns where the gases produced from incineration and an important source of energy. Although some toxic emissions are released in the process, the risks outweigh the benefits. Using a starved air incineration system (oxygen supply is limited) significantly reduces the toxic byproducts.
There are a few harmful substances that are a bit easy to dispose of. If you feel uncomfortable, you will be well advised to call a professional. If you decide to do the disposal yourself, ensure that you have personal protective equipment that will prevent contact or inhalation injuries from the fumes or burns. These include an apron, protective gloves and safety goggles.
If you plan on delivering to a disposal facility, make sure that the substances are in the right containers. They should preferably be in their original containers with proper labels. If you have to change containers, use those made of glass. Ensure that they are properly sealed and free from leakage. Hazardous materials should not be mixed with commercial or domestic waste under any circumstances.
