Garbage Expected To Double By 2025

Garbage Expected To Double By 2025

The garbage the world creates is only going to increase. In fact, the amount of municipal solid waste (MSW) generated globally every year is expected to double, according to new research by Worldwatch for its Vital Signs Online service. Doubling the amount of MSW would increase it from today’s 1.3 billion tons a year to 2.6 billion tons. There are two reasons why MSW is expected to double: increasing prosperity and urbanization.

Wealthier countries tend to generate much more MSW.  The members of the Organization for Economic Co-operation and Development (OECD), a group of 34 industrialized countries, lead the world in MSW generation at almost 1.6 million tons a day. By contrast, Sub-Saharan Africa generates less than one-eighth that amount, about 200,000 tons a day. OECD nations generate over two kilograms of MSW per person per day. In South Asia, the rate is less than a quarter of that amount with under half a kilo per person.

There is some variation within the top 10 countries for MSW generation. The U.S. generates almost seven times more than France, which is in the 10th spot. Some developing countries are starting to catch up. The top 10 list of top includes four developing nations (Brazil, China, India and Mexico). The four countries are on the list partly because of the size of their urban populations and partly because people in their cities are making more money and consuming more. The U.S. leads the world in MSW output at about 621,000 tons a day, but China is not too far behind at 521,000 tons a day.

The types of MSW generated include plastics, paper and aluminum, which tends to increase as prosperity increases and people move to cities. Only about a quarter of the world’s garbage is diverted from landfills through recycling, composting or digestion. MSW in landfills emits methane, a greenhouse gas with a warming potential 23 times greater than carbon.

There is a growing market for post-consumer materials, which could lead to more waste being diverted from landfills. The global market for scrap metal and paper is at least $30 billion a year. The market for waste management is about $400 billion globally. However, the UN Environment Program (UNEP) estimates that for waste management to become “green” it would require a 3.5 fold increase in MSW recycling globally, which would include almost a complete recovery of all organic material through composting or converting it to energy.

Americans need to reduce the amount of garbage they generate

The U.S. recycled only 34 percent of its MSW in 2010, up from 10 percent in 1980. Clearly, Americans need to recycle more, and consume less. American culture has an influence on the world. Americans can put that influence to good use by reducing the amount of garbage they generate.

One place to start is by reducing the amount of plastics we use, as the book “Plastic Free” by Beth Terry points out. Plastics never break down in landfills, and are made with petroleum, a fossil fuel. There are several easy ways to reduce the amount of plastic you use. Start carrying reusable bags to the grocery store and use them instead of those plastic disposable ones. Swap buying bottled water and use a reusable bottle filled with tap water.

I agree that we absolutely have to reduce our garbage output, but I also think that if we really tried, we could find a way to use what garbage we are making as some form of energy. After all, we have spent years mimicking science fiction...

We are murdering our planet, thus ourselves

I am grateful I will no longer be anything other than a small pile of ashes by then.

This sounds like a terrible problem. We humans need a more environmentally sustainable economy.

@vicky p...forced to do anything is total bs.last i heard this was a free country.
recycling isnt all its cracked up to bet either.water to wash it ,time to sort it ,fuel to truck it ,fuel to melt it ,fuel to bring it back, you emit as much if not more polution recycling a plastic bottle as you do making a new one...but hey ,if it makes you feel better by all means recycle it.
just dont try to FORCE me to do it.

everyone needs to be forced to recycle and everything needs to be made recyclable.

I just finished a bottle of extra virgin olive oil, and washed it out hoping to recycle it, but alas, it could not be recycled, so now I have vowed to buy olive oil in glass bottles.

"The types of MSW generated include plastics, paper and aluminum", all recyclable!
And: " American culture has influence on the world"??? There are plenty of countries that deliberately don't follow the US's way when it comes to environmental issues, take Germany for example, who obtained 50% of their energy from solar, a country that doesn't even see that much sunshine. And they recycle just about everything. Maybe bigger countries like the US need to know what it's like to live in refined spaces, like Japan, who are forced to recycle and reuse because they simply have no room to put away their garbage on a heap.
We need to reduce our waste back to what it was when "tips" were first conceptualised, and was fully biodegradable and therefore fit to be used as landfill once the waste had sufficiently decomposed. We shouldn't even be using plastic garbage bags anymore.

I hope the rebuilding will include some flood prevention measures.

What's more shameful is Republicans whining about raising the debt ceiling. The debt ceiling is raised…

Makes me proud of the time I spend signing petitions!
