Fires are a major hazard in waste management facilities. Dust is not only a primary contributor, but also a very threatening one. Under the correct conditions, the dust generated by the recycling process can self-ignite. This is particularly the case for metallic dust. As such, it is something to be taken very seriously.
In today’s article, we explore some strategies to prevent your site from becoming a headline.
Find The Source
Process optimisation is the key to successful dust management in recycling plants. If you can identify the source, you can find the ideal solution. Key recycling processes such as shredding and crushing are primary contributors, but sorting can also create dust particles. It’s also important to remember that most dust has metallic properties, so it will be attracted to any static electricity. As such, the machines themselves can be major contributors to dust problems in recycling. If you can locate your primary contributors, we can develop a strategy that is tailored to your needs.
Catch Dust Emissions Quickly!
In areas with high levels of vibration, it is important to catch dust particles before they have an opportunity to become airborne. Often, the best way to do this is with a combination of dust suppression systems. Depending on your operations, the solution is likely to be either water sprays, high pressure misting systems, or vacuum systems. Water-based systems make dust particulates heavy, preventing them from floating. Vacuum systems remove them from the air. Both approaches are equally effective, but are applicable in different environments. For instance, you do not want to spray water all over your electrical equipment!
Are You Working With Wood or Metal?
Different types of material create different types of hazards. Wood dust is associated with a wide range of health risks, such as respiratory issues, skin irritation, and eye infections. If paint is involved, wood dust can even lead to cancer. Clinically associated with gastric ulcers, irreparable kidney damage, and damage to the central nervous system, metal dust should never be inhaled. Thankfully, an ideal solution is to dampen these types of materials with foam sprinkler systems, which can protect both employees and buildings.
Targeted Systems For Odour Control
One of the major problems of recycling dust is that it smells. This can violate the Environmental Protection Act 1990 (EPA), as well as causing a general nuisance. Specific areas, such as hoppers and perimeter fences, can therefore benefit from misting systems that capture and contain dust particles. As such, targeted dust and odour control can be an ideal way of remaining compliant while reducing potential health risks to local communities.
Don’t Forget The Housekeeping
Much of the dust emissions in recycling centres can be avoided with rigorous maintenance. Recycling machines are designed to inhale and contain the majority of the particulates. While they can never offer 100% efficiency, by ensuring that your equipment is not leaking, you can make the correct calculations regarding dust control methods. For instance, your high-pressure misting system may not be effective if too much dust is being emitted, or a sudden breakdown might release a cloud that requires a serious hosing down. Accumulation around static electricity tends to be where the fires start, so keeping everything clean is crucial.
