For discussion of the management of unwanted or unusable materials

The Waste reddit

Waste - implies unwanted or unusable materials. The term is often subjective (because waste to one person is not necessarily waste to another) and sometimes objectively inaccurate (for example, to send scrap metals to a landfill is to inaccurately classify them as waste, because they are recyclable).

Examples include municipal solid waste (household trash/refuse), hazardous waste, wastewater (such as sewage, which contains bodily wastes, or surface runoff), radioactive waste, and others.

Collaborative Consumption

Collaborative Consumption

Hello, I'm currently pursuing my Bachelor in Arts, where I’m majoring in Economics. For my final year thesis, I'm conducting a survey on Collaborative Consumption. Collaborative consumption means people share or exchange goods and services, rather than owning everything individually. Some examples could be companies like Uber or Ola- where people take rides in cars they do not own, or companies like Airbnb- where people stay in homes they do not own.

My research is to identify what actually MOTIVATES people to engage in this kind of consumption. Could it be your concern for the environment? Or could it be because it is relatively cost-effective? Or is it just because engaging in such an activity brings peace an joy to an individual? To find answers to these questions, I would require your help.

Hence, I would greatly appreciate if y'all would fill the form, it won't take more than 3 minutes. All responses will be kept anonymous and will be used purely for research purposes. Thank You!

Here is the link to the form: https://forms.gle/hAPfeCu5sZ5retaVA

6 interesting facts about Coffee as a biofuel

  1. High Energy Content: Coffee grounds contain a significant amount of oil, up to 20% by weight. This oil can be extracted and converted into biodiesel. The remaining material, after oil extraction, is still rich in cellulose, lignin, and other sugars, which can be further processed into bioethanol or biogas.
  2. Carbon Neutral: Using coffee grounds as biofuel is considered carbon neutral. The carbon dioxide released during the burning process is roughly equivalent to the amount absorbed by the coffee plants during their growth. This makes it a sustainable alternative to fossil fuels.
  3. Waste Reduction: Millions of tons of coffee grounds are produced globally every year, most of which end up in landfills. Utilizing them as biofuel not only provides an energy source but also significantly reduces waste and the associated environmental impact.
  4. Efficient Conversion Process: Recent advancements in technology have made the conversion of coffee grounds into biofuel more efficient. Processes like hydrothermal liquefaction can transform coffee grounds into bio-crude oil, which can then be refined like traditional crude oil.
  5. Local Energy Source: Coffee grounds as biofuel present an opportunity for local energy production. Coffee shops and factories produce a steady supply of spent grounds, which can be converted into energy used for heating, electricity, or powering vehicles, potentially reducing energy transportation costs.
  6. Air Quality Benefits: When compared to some fossil fuels, biofuels from coffee grounds can produce fewer pollutants such as sulfur oxides. This can contribute to improved air quality, especially in urban areas where coffee shops are abundant.

Biodegradable Product or Recycle Products. Which one is good?

Absolutely! When considering the choice between using biodegradable products and recycling items, it's crucial to weigh the environmental impacts of both approaches.

Biodegradable products are designed to break down naturally, reducing the burden on landfills and ecosystems. They're a promising solution for single-use items like bags and packaging, offering a way to minimize waste and pollution.

On the other hand, recycling plays a vital role in conserving resources by reusing materials like plastics, paper, and glass. It reduces the need for raw materials, conserving energy and reducing greenhouse gas emissions associated with production.

Both approaches have their merits. Biodegradable products reduce waste and pollution at the end of their lifecycle, while recycling helps conserve resources and energy. The choice often depends on the specific item, its environmental impact, and the infrastructure available for recycling or composting.

Ultimately, a combination of both practices – using biodegradable products when possible and recycling items whenever feasible – can significantly contribute to a more sustainable future. It's about making conscious choices that collectively reduce our ecological footprint and preserve the planet for generations to come. What do you think?

The most shocking facts about business waste in the UK

Here are some of the most shocking facts about business. This means that over 63% of business waste is going to landfills, where it can release harmful greenhouse gases and leach toxic chemicals into the environment.

  1. UK businesses produce over 100 million tonnes of waste per year. That's equivalent to the weight of over 100 million small cars!

  2. Only 37% of business waste is recycled or composted. This means that over 63% of business waste is going to landfill, where it can release harmful greenhouse gases and leach toxic chemicals into the environment.

  3. The average UK office worker generates an estimated 1.47kg of waste per day. This includes everything from paper and cardboard to food and drink packaging.

  4. UK businesses spend an estimated £13 billion per year on waste disposal. This includes the cost of collecting, transporting, and processing waste, as well as the penalties for not complying with waste regulations.

  5. Businesses can reduce their waste by up to 80% through simple measures such as reducing, reusing, and recycling. This can save businesses money and help protect the environment.

Here are some specific examples of shocking waste figures:

  • 14 million glass bottles and jars are sent to landfill in the UK every day. This is equivalent to over 32 billion bottles and jars per year.

  • Around 18 million tonnes of waste are sent to landfill in the UK every year. This is enough to fill Wembley Stadium over 40 times!

  • UK businesses produce over 455,000 tonnes of plastic bottles per year. This is equivalent to over 9.1 billion bottles.

These shocking statistics show the urgent need for businesses to take action to reduce their waste. By making simple changes, businesses can make a big difference to the environment and save money in the process.

Is it true that food in an unopened container in a landfill (such as hotdogs sealed in the same package from its supermarket life) can survive over 20 years without decomposition? If so, why don't we have any historical foods surviving from centuries ago in air sealed containers?

Yesteday I helped my aunt prepare and store food to be used in my dad's promotion to Colonel in the National Guard Airforce (which took place today). As we were clearing the van before we stored food, my auntie found a bunch package of Chinese meatbuns (the white kind that with soft smooth texture that often comes with a paper sticker under them). My aunt was like "I bought those 4 months ago and couldn't find it!". We sadly had to throw it since its obviously now bad. But there was something peculiar about it. Despite being under the hot sun in a vehicle for the whole summer, it did not melt into a liquid pile of goo. Not only that, there was no sign of mould or discoloration and ohter associated things with food spoilage. From what I could smell of it from outside the sealed bag , it did not smell bad at all but had the smell so associated with that kind of white bread the Chinese use for their native cake and bread products. I could not smell the meat inside but the fact I couldn't detect anything typically like rotting meat amazed me so much.

This reminds me of a project I did in middle school where we had to research stuff related to trash and waste management. Is tumbled upon an article from a major news paper (can't remember the name but its a big brand name in the same league as say New York Times and People Magazine). It said something about unopened hot dog still in their plastic sealed containers being found in landfills from 20 years ago looking like in new considtion without discoloration nor did it have a strong scent that should have been apparent because of being refigerated so long even if its in a unopened package. The article emphasized that along with being in factory condition package, since it was in a garbage bag and hidden so long deep in over 50 feet high of a pile of trrash, it could not get oxygen and thus failed to decompose because no microbes were interating with the food.

The article was written around 1987 meaning that the aforementioned hotdogs and other trash it was commenting on would have been produced in the 1960s decade, To this day I still could not believe the article's claims despite being written by some big name professor or scientist (might have been both) who's in the field of evironmentalist and was doing some project for a university at the time the article was published..........

But seeing the Chinese meat buns not change at all despite being unrefigrated and outdoors during the hot summers (in even hotter temperature because it was stuck inside a car trunk the whole time) reminded me about that article.......

Now the first major question since I cannot believe it. Is this all possible that sealed food thrown into the center of a bunch of garbage would not be able to composee due to lack of oxygen and in turn lack of germs and other invisible tiny living things especially if its been thrown inside a tied plastic bag ortrash bag or something similar? I still am having difficulty beleiving this is actually real. Now the second question, how long until the food getst ot the point of disappearing? 6 centuries? A thousand years? 3 milennias? A whole eon of a million years or more? Now last and most of all, if food can survive so long without decomposition for decades, how come we don't have easily perishable food from the mid 1800s or even from World War 1 in a surviving state? Sealing food in a cloth, paper, ardboard, wooden box, and even modern day plastic wrapper seal has been in eistence since the late 19th century. Furthermore landfills were already a thing after the Industrial Revolution with places like N the Northern states having problems with running out of space in some ities and towns because of the heaps of trash piling up already shortly after the American Civil War. Landfills just became more and more as technology advanced before World War 1 at the even of the 1900s. The existing amount of open lands being used to pile more and more trash has boosted up even further after WWII. So I'm wondering why don't we have surviving ground beef hidden in a trash pile in Germany thats been wrapped in a cylander plastic dated container dated from 1922 hidden in some landfill in operation for 90s years? Why aren't there some ancient sausage linked wrapped in paper cloth in early trashbags in a landfill thats been in operation since 1879? Since piels of trash limit oxygen and can cause hotdogs to survive so long for decades, not to mention the Chinese meatbuns in my Auntie's trunks surviving one whole hot summer without decaying into a different state, why don't we have surviving food especially whose in plastic air sealed wraps from the 19th and early 20th centuries in very old landfills?
