Summary of Certain Articles Read in Selecting a Trash Trek Topic
Garbology-Difference Engine: Talking trash
- The first paragraph is about the incinerator in Toy Story 3
- If, in real life, the plant had been built prior to 1989, the plastic toys would have produced a nasty dose of dioxins and furans
- Dioxins-”A highly toxic compound produced as a by-product in some manufacturing processes, notably herbicide production and paper bleaching. It is a serious and persistent environmental pollutant. A heterocyclic organochlorine compound; alternative name: 2,3,7,8-tetrachlorodibenzo para dioxin (abbreviation: TCDD) ; chemical formula: C12H4O2Cl4”
- Furans-”A colourless volatile liquid with a planar unsaturated five-membered ring in its molecule. Chemical formula: C4H4O”
- Another way of stating that would be “toxic emissions from combustion taking place in the present of chlorine”
- Before then, few people were aware that such chemicals were a serious health hazard
- The second paragraph was about emissions and the environment
- “Industry subsequently spent billions retrofitting incinerators with activated-carbon injections”
- “Thanks to new regulations, the emission of such toxic chemicals from waste processing has been reduced a thousandfold”
- The third paragraph is about municipal incinerators
- “In America, most communities prefer their waste to be composted”
- “The landfills are nowhere near their own backyards”
- The fourth paragraph is about landfills
- “Puente Hills Landfill in Los Angeles, the largest of the 1,900 municipal landfills in America, is over 500-feet high”
- This landfill can generate electricity for 70,000 homes with its methane that it produces
- The fifth paragraph is about transporting garbage
- NYC transports most of its garbage by truck
- The sixth paragraph is about how landfill shortage is a big issue
- In China they are running out of space for landfills
- Although using incinerators is awful for the environment, officials are now having to reconsider the issue of incineration to the non-stop increase of landfill space
- WTE plants are saying that they have their incinerators burning at 850 °C, which breaks down the molecular bonds in dioxins and other toxic chemicals, basically stating that having the incinerator at that heat is harmless
- Also, “the flue gasses are then cooled in heat exchangers that raise steam to drive the electricity-generating turbines”
- flue gases-"A mixture of gases produced by the burning of fuel or other materials in power stations and industrial plants and extracted via ducts"
- The seventh paragraph is more about flue gases
- In order to remove sulphur dioxide as well as various acids and heavy metals from flue gases, the flue gas have to go through a cleaning system that filters fine particles from the flow and then scrubs the gas
Zero Waste: Recycle Every Material (An article about TerraCycle)
- What TerraCycle offers:
- TerraCycle Canada is the local version of a global company that has repurposed more than 2.6 billion pieces of food and beverage, office and school supply, e-waste and other hard-to-recycle streams
- These collections have raised more than US $8 mil. dollars for charity through its various packaging reclamation programs
- TerraCycle will offer the first of 25 markets in which the international company operates to offer a curbside pickup of its recycling programs
Recycling The Hard Stuff
- 22.4 million tons of plastics produced in the United States in 1998, only about 5.4 percent were recovered for recycling
-
Plastics used in durable goods (such as cars, electronics, and appliances) account for the largest proportion by weight of plastics in U.S. municipal solid waste (MSW)
-
Plastics are difficult to separate and therefore hard to recycle
-
Separating the plastics can limit the recycling rate
-
Products often contain as many as 20 different types of plastic materials as well as non-plastic materials such as wood, rubber, glass, and fibers
-
Operation costs for processing recycled plastics are estimated in the range of 10-20 cents per pound
-
Recycled plastic resin is competitive with costs for existing virgin plastics
-
The incinerators are used to burn up garbage but are creating pollution to the environment and also the heat made by the fire is used to create energy
-
About 50% of the people in Toronto recycle things properly
-
Compost is mostly contaminated with recycling therefore making the “once recyclable” things not recyclable
Less Is More
-
Sieben Linden is one of the fastest growing towns in Germany yet it is made completely out wood, straw, and mud which is very eco-friendly
-
Growing your own food and owning less dramatically reduces waste
-
It is possible to live green without sacrifice
-
In the last 20 years the amount of waste made is increasing by 3 percent each year
-
Collecting garbage less often will make you throw away less
-
Making people pay per amount of garbage is a solution
-
Soda cans are half as thick as they were 40 years ago showing that we are trying to improve package size
-
HP’s laptops are 90% recyclable
-
There are still many opportunities to improve in electronic waste
-
Making companies pay for greenhouse gasses can also reduce waste
Beverage Container Recycling Update
-
Provinces with deposits on reusable soda cans collect more of them
-
Canada collects 97% of beer bottles bought
-
Alcohol has the highest collection rate
-
Beer bottle recycling is a really good business because we think we are getting money back
-
Alberta collects the most bottles because their system is automated
-
Getting rid of the penny increased the collection rate because companies were forced to give more
-
Free pick up programs also increased the collection rate
Markham’s diversion program succeeds with clear bags over carts
-
Markham’s street collection garbage bags are now clear
-
This forces people to recycle due to social pressure
-
People can see what is in your bag
-
Garbage collectors can accept or reject depending what is inside the bag
-
Average weekly household garbage generation has decreased by 15% in the last 3 years because of this
-
People did not like this because of the worry for “Garbage Police”
-
But Markham launched an awareness program to make sure the system goes in place
