It depends on what type of foam it is and where it is: whether it's exposed to head, humidity, open air, etc. I carried a polyurethane mattress out of an old person's spare bedroom in 2010. It had been purchased in the 1960s and had turned mostly to a granular, sand-like material. Thankfully it was enclosed within a zipped mattress cover or it would have been a huge mess. I have also seen the polyurethane within a 20-year-old house door granulate and pour out the bottom, likely assisted by burrowing insects.
Plastic milk jugs can take hundreds of years to decompose in the environment, as they are made of high-density polyethylene (HDPE), a type of plastic that degrades very slowly. Recycling the milk jug is a more environmentally friendly option.
Batteries can take hundreds to thousands of years to decompose in the environment, as they contain toxic chemicals that can harm the ecosystem.
It can take anywhere from 20 to 200 years for a jacket made from synthetic materials such as polyester or nylon to decompose in a landfill. Natural materials like wool or cotton may decompose more quickly, depending on environmental conditions.
Bricks are very durable and can take hundreds to thousands of years to decompose naturally in the environment. They are usually not biodegradable and can persist for a long time if not properly disposed of or recycled.
it will take hundreds of years to break down.
