WASTE MANAGEMENT
WHAT IS WASTE MANAGEMENT
 |
| reduce-reuse-recycle |
Waste management is the collection, transport, processing or disposal, managing and monitoring of waste
materials. The term usually relates to materials produced by human
activity, and the process is generally undertaken to reduce their effect
on health, the environment or aesthetics. Waste management is a distinct practice from resource recovery which focuses on delaying the rate of consumption of natural resources. All waste materials, whether they are solid, liquid, gaseous or radioactive fall within the remit of waste management.
Waste management practices can differ for developed and developing nations, for urban and rural areas, and for residential and industrial producers. Management of non-hazardous waste residential and institutional waste in metropolitan areas is usually the responsibility of local government authorities, while management for non-hazardous commercial and industrial waste is usually the responsibility of the generator subject to local, national or international authorities.
(human waste)
We generate millions and millions of tons of waste per year from industry, businesses and households.
In the 1999 State of Environment Report for South Africa (DEAT, 1999), it
was determined that there were over 42 million cubic metres of general
waste generated every year across the country, with the largest proportion coming from Gauteng. According to the report the average amount of waste generated per person per day in South Africa was 0.7 kg.
In 2007 in only 10 municipalities there were almost 1,3 million tons of household waste collected at landfill sites. (http://www.sawic.org.za)
oSouth Africa has six metropolitan municipalities, namely Tshwane, Johannesburg, Ekurhuleni, Ethekwini, Cape Town and Nelson Mandela. There are also local municipalities and district municipalities. So 10 is just a handful of the total number!
As our population grows and our consumption of consumables grows so will the amount of waste grow.
At present most collected waste is disposed of in landfills. Within the landfills biodegradable waste produces methane, a powerful greenhouse gas.
Decomposition in a landfill is slow. Plastic waste in particular is a challenge as the volumes take up valuable space in landfills, and although we don't know exactly how long it takes to degrade, it is believed that it can take thousands of years to break down.
Because we have a throw-away society, not much thought is given to the fact that valuable energy is used every time new products are produced which are later merely disposed of.
Natural resources are being used and abused at an unsustainable rate. Although there is an abundance of everything on earth - if we abuse it and use it faster that it can reproduce then it won't be available for our future use.

WHY WE SHOULD DO THIS?

| manage our waste!! |
Humans produce waste (and we're not talking about natural bodily waste!). Just think
of your household rubbish bin and how much you throw away every day!
• Paper (newspaper, envelopes, white paper, printing paper, magazines,
egg containers, toilet paper rolls, boxes, tissues - what else can you think
of?)
• Plastic (bottles, gladwrap, food containers - yoghurt, cottage cheese,
prepared food containers, frozen food and fresh food bags and containers;
medicine bottles, bubble wrap, cleaning agent bottles - what else can you
think of?)
• Glass (colddrink bottles, food jars, broken glasses - what else can you
think of?)
• Metal (colddrink cans, food tins, tin foil - what else can you think of?)
• Food - food scraps, vegetable peels, bread, leftovers - what else can you
think of?
• Garden waste (grass, leaves, dead plants, weeds etc)
• What about lightbulbs, batteries, old toys, clothes, books, electronic
appliances, paint containers?
In addition to household waste, there is also waste from litter and street sweepings, the commercial sector (like shops, restaurants, hospitals etc.), industrial sector (like manufacturers), agricultural sector, construction and demolition sector, mining sector and energy producing sector.
With so much waste being produced, we need to do what we can as individuals to manage our waste so it doesn't harm the environment or our own health.
We do and always will produce waste. We won't change that. Unfortunately in the past not enough thought was given to the impact of our waste practices
on our planet. Fortunately that is now changing worldwide.
In areas where there has always been service delivery, there hasn't been much concern beyond putting the rubbish is in the bin, and having it collected by the municipal waste management companies. We are only conscious of
the amount of waste we produce when it's not collected!
But we can no longer NOT be concerned. We have to start being responsible for our actions and our impact on the environment and our planet.
Although we cannot change the fact that we produce waste - we have in our power and control to determine how much waste we do produce, how we manage our waste, and what we do with our waste.
We need to work together to manage our waste in a sustainable way to protect our Planet. We can do this by:
• reducing our consumption (limiting unnecessary consumption and being
conscious of our purchasing choices, especially around packaging)
• re-using/repurposing what we are able to
• recycling
• creating home compost
By doing these we can limit the amount of waste that is sent to our landfills.

Each individual, each household, each business and each industry can make a difference.
As a collective we can make a huge difference

Reducing your consumption is better than reusing.
• Reusing is better than recycling or composting.
• Reducing, re-using, recycling and composting are better than
disposing of our waste
• Reusing is better than recycling or composting.
• Reducing, re-using, recycling and composting are better than
disposing of our waste
* remember that every little BIT WORKS!! GO GREEN!!.
Be responsible.
MAKE YOUR MOVE!!

SAVE THE OCEAN
Why we should protect our oceans?
 |
| save Philippine ocean |
People need air to breathe, water to drink, food to eat, new medicines, a climate we can live in, beauty, inspiration and recreation. We need to know we belong to something bigger than ourselves. We want a better future for those we care about.
Because
the oceans are the largest ecosystems on Earth, they are the Earth’s largest
life support systems. To survive and prosper, we all need healthy
oceans. Oceans generate half of the oxygen people breathe. At any
given moment, more than 97% of the world’s water resides in oceans.
Oceans provide a sixth of the animal protein people eat. They’re the most
promising source of new medicines to combat cancer, pain and bacterial
diseases. Living oceans absorb carbon dioxide from the atmosphere and
reduce the impact of climate change.
The
diversity and productivity of the world’s oceans is a vital interest for
humankind. Our security, our economy, our very survival all require
healthy oceans.
So
when Marine Conservation Institute works to save the North western Hawaiian
Islands or the Arctic Ocean, when we work to get agencies to devote more energy
to research, monitoring or enforcement of laws, we are working to save the
oceans for all of us and future generations.
Whether
you live on the coast or far from it, whether you eat seafood or not, you and
the future of all those you love depends on healthy oceans.
Our
job is to see that you have healthy oceans. It’s the smart thing and the
right thing to do.
