WASTE DISPOSAL IN ADELAIDE
Ever since Al Gore’s An Inconvenient Truth came out in 2006, environmental concern and awareness have risen dramatically. People are considerably more cautious now about what they put in the earth and where they put it. Before organizations started taking notice and action, open landfills were allowed to grow beyond hope of management or control. Sea dumping for chemical wastes and toxic refuse was widespread. Styrofoam and rubber were incinerated in compounds that spewed black smoke 24/7. These are just some examples of improper waste disposal methods that have since left massive scars on the environment.
Thankfully, we as a race have grown more careful and more considerate since then. Recycling centers and approved waste processing facilities have tripled in number worldwide. Various environmental and global health organizations are now getting the funds and attention they need. Waste treatment, containment, and disposal are monitored closer than ever.
And while there are some countries that have yet to completely embrace this green revolution, there are others – a good number, in fact – that can be considered pioneers and leaders in it. For instance, for excellent examples of proper waste disposal, Adelaide is one such city that has efficient systems in place.
APPROVED TYPES OF WASTE DISPOSAL
While this may be the most popular method of waste disposal, it is also one of the more frowned-up procedures – simply because it’s still a potential health hazard. While the concept of a landfill is to bury the waste and refuse in the ground to help aid the break-down process, a lot of landfills remain unmanaged and exposed. Water contamination is a serious possible risk as long as you’re within the immediate vicinity of a landfill. Strong presence of methane and other gases linger in and around the general area despite odor elimination and treatment processes.
There are better systems in place nowadays – such as segregation, inspection, and treatment – to ensure that what’s going in the earth is one hundred percent biodegradable, but a good number of organizations and governments are reconsidering landfills in favour of safer, more efficient options.
Another popular disposal method, incineration – as the name suggests – involves burning municipal solid wastes at extremely high temperatures, effectively converting them to gaseous residue. While there is the risk of possible air pollution thanks to the toxicity the waste releases during the incineration process, a lot of areas still favour this procedure over other methods. This is largely due to the fact that incineration/combustion can reduce solid waste volume by as much as 30 percent its original volume.
This is why countries that have precious little land left to utilize for landfills – such as Japan and Korea – employ this as their primary method. And although land availability isn’t a huge problem in cities like Adelaide, it’s still a far more acceptable method than land and sea disposal.
When comparing dictionary definition, composting may seem a lot like the landfill procedure. Indeed, composting involves burying waste substances in the earth and letting the natural break down process take over. The biggest difference between the two is specificity. While landfills are more of a communal dumping place for general refuse, the only waste that goes into composting is the organic, biodegradable kind. Of all the methods used, composting is by far the safest and greenest choice. It takes rejected organic matter and turns it into a nutrient-rich compost for better soil without risk of air pollution or water contamination.
Composting is the preferred method for – and is closely tied to – organic farming. Instead of spending a couple hundred bucks on quality fertilizer, farmers allow carbon-based material to sit in a specified part of their plot and let microbes do what they do best; decompose it. After a few months, they have fresh compost to mix with their soil. Perhaps the only drawback to this method of waste disposal is its particular nature. Non-organic waste cannot be taken care of through this method, and neither can hazardous or toxic refuse. The procedure also takes quite a while before it can be completed. It can take months for the matter to be broken down completely.
While not really a disposal method per se, a lot of major cities now are encouraging trash segregation. It benefits the disposal system by ensuring that the right kind of waste gets sent to its respective place. Trash is typically sorted into biodegradable, non-biodegradable, toxic/hazardous/chemical waste, and paper wastes. Paper wastes can be sent to recycling centers to be reused as paper products. Toxic and chemical wastes are sent to special government-approved treatment plants or processing facilities to be properly – and safely – disposed of. Biodegradable refuse, as mentioned in the previous paragraph, gets sent to organic farms and centers to be used as compost. And non-biodegradable waste gets sent off to be further inspected, segregated, or properly disposed.
In terms of waste disposal, Adelaide strongly utilizes the segregation and containment method through various means. For instance, hiring skips – or dumpsters, in US English – to properly contain trash from small-scale events and large-scale construction projects is seen as the most sensible and most efficient way waste disposal method available.
