WHAT DO YOU KNOW ABOUT WASTE?
Waste can
usually be found around residential, industrial and commercial areas. Waste can
be categorized into 5 types namely liquid waste, solid waste, organic waste,
recyclable waste and hazardous waste. The waste is extremely harmful to humans
and marine life, especially solid waste.
WHAT IS SOLID WASTE?
Solid waste
includes a wide range of products available in your home along with commercial
and industrial locations.
Solid waste is
commonly broken down into the following types:
- Plastic waste – This consists of bags, containers, jars, bottles and many other products that can be found in your household. Plastic is not biodegradable, but many types of plastic can be recycled.
- Paper/card waste – This includes packaging materials, newspapers, card boards and other products. Paper can easily be recycled and reused.
- Tins and metals – This can be found in various forms throughout your home. Most metals can be recycled. Consider taking these items to a scrap yard or your closest recycling center to dispose of this waste type properly.
- Ceramics and glass – These items can easily be recycled. Look for special glass recycling bins and bottle banks to dispose of them correctly.
While most solid
waste can be recycled, however, not everything we can recycle. There are items
that we cannot recycle. These include:
- Plastic bags or recyclables inside plastic bags
- Takeaway coffee cups
- Disposable nappies
- Garden waste Polystyrene (foam)
- Bubble wrap
- Syringes or medical waste
- Dead animals
- Oils
- Ceramics, ovenware or light bulbs
Based on
statistics extracted from the scales at the Madang Disposal Site, food waste
recorded the highest volume at 45% followed by 21% of paper and 18.4% of
plastic per month in 2010.

In this article, we will focus on the dangers of plastic waste on our earth. According to the study, plastic waste in Asian countries is increasing. However, China has decided not to take waste paper, plastics, textiles and other materials - any by-products made when the metal is separated from its ore from the United Kingdom. This is because China is trying to reduce pollution in its own country as a result of too much plastic waste. Therefore, the United Kingdom is seeking a new 'victim' to dispose of their plastic waste, Malaysia. Over the past year, it was reported that Malaysia imported 157,299 tonnes of plastic waste, up 273 per cent compared to the previous year.
Plastic
waste is the accumulation of plastic objects such as plastic bottles and more
in the earth's environment that adversely affects wildlife and human habitat.
They are also classified as large quantities of non-recyclable plastics that
end up in landfills or the developing world, dumped into unregulated landfills.
Non-recyclable plastics enter our environment, polluting our oceans and causing
damage to our ecosystem. In less developed countries, the most plastic waste
eventually ends up in the oceans, which means that marine animals are very
dangerous. However, plastics are slowly declining (taking 400 years or more)
due to their chemical structure, which presents a major challenge.
Plastic
waste disposal can affect marine life. Marine animals can be caught in plastic
objects (such as plastic rings holding canned drinks together), drinking
plastic, and exposed to plastic chemicals, which can change their physiology from
time to time. A recent study found that 'turtles oceans that consume only 14
pieces of plastic are at higher risk of death. In particular, young turtles are
at higher risk because they tend to drift with the same current that attracts
plastic waste, and they are less selective than their elders about what they
eat.
Apart
from the disposal, the burning of plastic waste is also very harmful to human
health. Waste combustion or incineration releases various pollutants into the
air, water and soil. Air emissions include carbon monoxide, greenhouse gases,
acids (Nox, Sulfur dioxide, HCI), dioxins, furan, heavy metals such as mercury,
cadmium depending on the type of residue burned. Direct and indirect exposure
to such substances may include through inhaling air, direct contact with
contaminated soil or water, or digestion of toxins entering the food chain that
may have adverse health effects affecting the neurology, immune, reproductive
and endocrine systems.
Therefore,
various measures have been devised to overcome this problem. For example,
reducing plastic use, increasing awareness about plastic recycling such as
education. Education is very important because it can change people's
knowledge, attitudes, and behaviours towards plastic waste management.
Education can be given through direct teaching method or simulation method in
schools and home.
Today,
many non-governmental companies and social enterprise are set up to help
address the problem of plastic waste disposal. For instance, UPCycled Shack by
Tressie Yap is a social enterprise where she taking a different way to educate
the underprivileged communities to make them see trash as their free capital of
the businesses. She made all the communities that she is working with her
business partners in crafting trash to distributed goods to make the
environmental and economically sustainable at the same time. She gave the idea
of upcycled the unused objects and switched them to other new functionalities.
Since she is a fashionable person, she loves to make bracelets, necklaces,
earrings and many other accessories.
RECYCLING VS UPCYCLING?
Technically,
upcycling is described by some as reusing a material without degrading the
quality and composition of the material for its next use. It is a way to give
your old things a ‘new life’ and can often be even more environmentally
friendly than recycling. Upcycling isn't just the practice of transforming old
materials into useable objects, it's the process of breathing a new lease of
life into well used and loved items to give them a new story and personality.
All this while at the same time creating something useful, functional and
beautiful. Upcycling is the process of converting waste or useless products
into quality new products or for a better environmental value. It is different
from recycling, where recycling is the process of taking waste, generally
consumer materials – plastic, paper, metal or glass – breaking it down and turning
it into a reusable product.
THE BENEFITS OF UPCYCLING:
The
environmental benefits of upcycling are enormous. It doesn't just help curb the
shocking volume of discarded materials and waste finding its way into landfills
each year, it also reduces the demand for the use of new or raw materials in
production. Lower demand for these materials means a reduction in air
pollution, water pollution, and greenhouse gas emissions, helping us conserve
our precious global resources.
Refuse: Say no to pre-packaging & excessive use of plastics.
Reduce: What cannot be refused - by avoid unnecessary purchases.
Reuse: What cannot be reduced - by reuse/avoid single use items.
Recycle: What cannot be reused – try to recycle less.
Rot: The compostable & food waste for earth nourishment.
