Which plastics can be recycled what type of plastics are these and give two examples?

Plastics that can be recycled are typically categorized by their resin identification codes, which range from 1 to 7. The most commonly recycled plastics include PET (Polyethylene Terephthalate, code 1), often found in soda bottles, and HDPE (High-Density Polyethylene, code 2), used in milk jugs and detergent bottles. Other recyclable plastics include PVC (code 3) and LDPE (code 4), though recycling rates for these are generally lower. Always check local recycling guidelines, as capabilities can vary by region.

How much synthenic fertilizer is produce and used in the US?

As of recent data, the United States produces approximately 25 million tons of synthetic fertilizers annually, with nitrogen fertilizers being the most widely used. The country utilizes around 18 million tons of nitrogen, phosphorus, and potassium fertilizers collectively each year in agricultural practices.

However, environmental concerns are rising regarding their impact on soil and water quality.

How long does it take a banana tin can and tennis shoes to degrade?

A banana typically decomposes within a few weeks to a few months, depending on environmental conditions. A tin can can take anywhere from 50 to 200 years to degrade, as it is made of metal that resists corrosion. Tennis shoes, primarily made from rubber and synthetic materials, can take 500 years or more to break down in landfills. Overall, the degradation time varies significantly based on the materials and environmental factors.

What is the waste that takes up to 5 months to break down?

One type of waste that can take up to five months to break down is food waste, such as fruit and vegetable scraps, in composting conditions. While composting can accelerate decomposition, factors like temperature, moisture, and the type of food waste can influence the breakdown time. Other organic materials, like yard waste, may also take a similar duration to decompose fully. Proper management can enhance the speed of decomposition.

Should on food packaging it say whether its recyclable?
