Many years, depending partly on the chemical conditions in the heap where they are dumped.
It depends on the environment.
In particularly corrosive environments - say on the salty sea shore in a tropical country, just a few months. But in Antarctica, it will never decompose, it'll stay frozen in the ice forever.
Synthetic fabrics, such as polyester and nylon, can take hundreds to thousands of years to decompose in a landfill site due to their non-biodegradable nature. This long decomposition time contributes to environmental pollution and sustainability issues.
Students are estimating the quantity of plastic bags disposed of in a landfill in a day by conducting research, data collection, and analysis. They may visit the site, gather information on daily waste disposal rates, and calculate the approximate number of plastic bags being discarded based on their findings.
"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.
Leaking chemicals from landfill sites can flow into groundwater, surface water bodies, and soil surrounding the site. These chemicals can contaminate drinking water sources, harm aquatic ecosystems, and potentially affect human health if not properly managed and contained.
As a polymer, cornstarch can form a thick gel when mixed with a liquid, making it useful for thickening sauces and soups. It traps liquid within its structure, creating a smoother texture in food products. Additionally, cornstarch can help stabilize emulsions and prevent crystallization in frozen desserts.

stuff that goes in a landfill.
What a snake pit this topic is! Disposable diaper (nappie) opponents claim that the plastic bits of of the product can take u to 500 years to decompose in a properly organized landfill site where they are not exposed to oxygen, light or water. The cloth only users say the cloth units decompose in about 6 months. There is no reason why the cellulose bits of a disposable wouldn't vanish in the same time. Leavng just the undegradable plastic bits. Here is the however ... Excavations in landfill site indicate the anoxic conditions do not permit organics to dispose quickly, especially if contained in the air tight, water tight, green trash bags. After 30 years in landfills even steaks and other food wastes were essentially "fresh". In another twist in the Canadian Innuit mothers have gone to the use of disposables to replace cloth, or the old standby, moss. Garbage pickup in the north being what it is, and the several months of cold and dark does not promote either decomposition or disposal in secure landfill sites. The landscape is littered with years worth of freeze dried, wind blown disposables.
if it is non-biodegradable it means that if left in a landfill site it will not rot away naturally for years like the old plastic bags, most plastic bags these days are biodegradable however. Hope I helped

Landfill sites typically contain household waste such as plastic, paper, glass, and food scraps, as well as commercial and industrial waste. Hazardous materials, such as chemicals and batteries, are also disposed of in specialized sections of the landfill. Additionally, construction and demolition debris like concrete, wood, and metal are commonly found in landfill sites.

Solid Waste would be left in piles at a landfill site because solids aren't recyclable, so they therefore go to the land fill site like many other things.
The liquid that can seep from a landfill site is called leachate. It is formed when rainwater filters through the waste, picking up various contaminants along the way.
Up to 1000 years. I didn't believe it at first but looked at multiple site and confirmed it
It creates methane that can be used to create electricity
