Can you put cheese in the compost?

No, you shouldn't put cheese in the compost pile. Dairy products, greasy or oily foods, and meat attract foraging wildlife. Generally, once a hungry critter finds a food source, the stop becomes permanent on the animal's nightly rounds.

What is baking paper made of?

== High density paper treated with acid == Baking paper (Vegetable parchment) is made using high density paper (made from regular wood sources) that goes through an acid treatment. The result is strong, non-stick and heat-resistant. Silicone and other oil-based coatings are sometimes added to make it non-stick.

It is also good for easy clean up, it is not just for baking you can use it to line a basket to put food in at parties

How do you decompose non-biodegradable waste?

As decomposing is a biological process, you cant. You have to burn it or bury it.

Lawn Care
Waste and Recycling

Can you fertilize your lawn with used motor oil?

No...there is no 'nutrition' in used motor oil. It's petroleum. Fertilizers work by adding nitrogen and other nutrients to the soil. Besides, why on earth would you want to spread that on your lawn? Doing so causes it to leach into the ground, the water supply, and will probably kill whatever you might have growing.

Petroleum is toxic to plants, so keep it far away from any growing things. Used motor oil also picks up heavy metals from the engine, especially old engines, so it's even worse.

Air Pollution

How bad is the air in Beijing?

Another point of view:

It is bad. China had a per capita carbon emission of about five tons in 2008, exceeding the world average of 4.18 tons per capita.

Older answers:

Data on the air quality in Beijing is difficult to come by and difficult to interpret when available. Factors such as the location of monitoring sites strongly impacts the perception of quality. However, the following external information may prove useful.

According to the European Space Agency, Beijing and its neighbouring north-east Chinese provinces have the planet's worst levels of nitrogen dioxide, which can cause fatal damage to the lungs. The Chinese independent environmental researchers list Beijing as No. 28 out of 113 on the Chinese list of polluted cities in China.

Beijing does not make the Top 10 list of polluted cities for particulate matter (Wikipedia data), or the Forbes Top 25 most polluted cities in the world (data prepared by Mercer Human Resources Consultants).

China itself is second on the list of carbon dioxide emitters in the world (Wikipedia data).

106 Tons of Carbon Dioxide per year:

  • United States: 2,795
  • China: 2,680
  • Russia: 661
  • India: 583
  • Japan: 415
  • Germany: 356
  • Australia: 300
  • South Africa: 232
  • United Kingdom: 212
  • South Korea: 185

It may be assumed that the majority of these emissions are related to heavily industrialized areas such as Beijing. There will be a burden of other pollutants with the carbon dioxide.

Municipal environmental departments in Beijing report deceases in SOx emissions of several percent in recent years.

Previous Answers
  • Not too bad.
  • Beijing air is just like that of New York or New Delhi.
  • Not true; their air is so bad you can't even see anything. The only reason they started to clean it was because of the 2008 Olympics event.

Since the 1980s, the city has experienced rapid industrial development, urbanization and increased traffic. Pollution from coal-fired power plants and emissions from slow-moving gas guzzlers have combined to cast a dun-colored haze over Beijing and its sprawling suburbs.

Waste and Recycling

Is it worth undertaking major repairs to a piece of equipment to prolong its useful life?

It would depend on what the equipment is for, and whether a new replacement is cheaper. On environmental concerns, you'd have to consider if the repair would use less resources including fuels than replacement; and if the replacement would use less fuel for the same work.

Why do people have worm farms?

People have worm farms because worms help plants and other living things such as: food for birds. Worms soften the soil for the trees so water can get into the ground easier and can reach the tree roots. They can also have worm farms for fishing bait.

How do you dispose of Liquid Fire Drain Opener?

How to rid yourself of Liquid Fire The best way to dispose of it would be to pour small amounts down the drain, wait awhile, and then flush it out with some water. Repeat this while waiting in between sessions because the water will cause the drain opener to heat up quite a bit. If you want to keep the flora in your septic tank alive it would be best to neutralize it. Liquid fire is sulfuric acid. You can first carefully mix it with a base thus creating a salt and water and then flushing down the drain. Common bases you could find around your house are baking soda (sodium bicarbonate) and ammonia water (ammonium hydroxide). The latter will actually flush fertilizer (ammonium sulfate) down your drain :)


Your local town or county should have a place where you can dispose of chemicals that you no longer want to use, such as paint, paint thinner, fertilizer and so on. This is much better than tossing it into the regular garbage or into the sewage system.

Plastics and Polymers

What are some bad things about plastic?

"One bad thing about plastic is its bad for the enviroment. You should use reuse able things that isn't plastic. Most wastes biodegrade (compost) but plastics do not."

Plastic is not inherently "bad for the environment", it depends entirely on how you manage your plastics waste. If you carelessly go around throwing plastic bags and empty plastic containers onto the ground, then of course it's a problem. If you collect and recycle them then there isn't a problem. Synthetic plastics in the environment basically just sit there - they are not intrinsically toxic or harmful.

The comment "most wastes biodegrade but plastics do not" is complete nonsense. Firstly, plastics DO biodegrade, they just do it very slowly. Also, if you place paper (recycled paper or any other type) into a landfill site, THAT will not biodegrade for years either. The reason is simple - biodegradation requires oxygen, and the inside of landfill sites are basically oxygen-free. No bugs can survive there, so no paper can degrade.

The whole "use paper cups, they're more environmentally friendly" thing is pseudoscientfic claptrap. They key point is the way that you handle and manage the waste, not what the waste is made of.

What are advantage of metal for furniture?

There number of reasons, for example, durable, flame-retardant, and it's very hard to wear out.

It definitely makes it more stable and gives a support to last it longer. I've always been pro wood furniture, until I talked to one of the girls on dream marriage who told me that her metal frame lasts since her childhood.

Nuclear Energy

Why not dispose of nuclear waste on the moon?

There are two major problems with this. The first takes the pragmatic view of this option and the other aesthetic.

Even in 2010, a jump to the moon is nothing to trifle at. It still takes time, it still takes resources, and more importantly, it still costs money (and a lot of it). But that's not even taking into account the waste you would have to transport. Nuclear waste is going to be heavy, meaning you need a bigger rocket, more rocket fuel, and more money. For these reasons, disposing of nuclear waste on the moon would be astronomically expensive and completely impractical.

Additionally, we have polluted the Earth quite effectively. Do you really want to extend that to the Moon? It may be a hunk of rock devoid of life, but it is currently devoid of pollution as well. I don't like the thought of polluting the Earth, much less the extension of pollution outside of Earth.

Can you reuse oil after frying shrimp?

You can reuse oil after frying anything, but its generally not recommended. You should try to use oil only once, if you can. Reheating oil actually causes it to release toxins, they're not good for you, so you should try to avoid this if you can.

Ans 2 - You can re-use oil adequately if it hasn't been burned. I generally put my oil through a paper coffee filter after each use. This will give you 7-10 more uses before it's useless.

Bananas and Plantains

What effect does a paper bag have on a banana?

Placing bananas in a paper bag or any other enclosed environment will hasten the ripening process. This is due to the fact that, as a banana ripens, it emits ethylene gas. Ethylene gas is essential in the ripening process. If you place bananas in a bag, the gas concentrates and the ripening process accelerates. Ethylene gas is what banana importers use to accelerate the ripening of bananas prior to sending them to market.

How is trash waste disposed in space?

Liquid waste (urine) was collected in a Urine Collection Device, used in common by the crew of an Apollo spacecraft. Roll-on cuffs provided personal sanitary protection for the astronauts using the collection device. The urine was then transferred through the Urine Transfer Tube to a tank, from which the liquid waste was vented into space.

Fecal matter was sealed in a Fecal Bag with a liquid germicide and sealed again in an outer bag. This solid waste was then placed into a Sanitation Box built into the spacecraft.
