These items would take the longest time to decompose by natural means in a landfill:
Quickest things to decompose:
It can tale between 50 and 80 years for a boot rubber sole to decompose. Different items can take different amounts of time to decompose in a landfill. For example, a banana peel can take a few days, but an aluminum can take between 200 and 500 years.
Chemistry that deals with only natural items
Linen is recognized to be the world's strongest natural fiber. It is 30% stronger than cotton fabric, making it extremely durable and contributing to the longevity of linen items.
There are many everyday household items that one can use as natural cleaning products. This includes items such as vinegar, baking soda and lemon juice.
X-rays have the highest frequency in the electromagnetic spectrum.

Worms decompose waste from other animals and turn it into soil or other nutrient-rich items.
The simple answer is that it does! Everything decomposes eventually. Unfortunately, many household, commercial and industrial waste products are made from materials that take an awfully long time to decompose; plastic for example. Some types of plastic can take up to 50,000 years to decompose fully! Other waste items such as tin foil can take upward of 100,000 years! Even with the (comparatively recent) advent of recycling, much of the waste that gets assigned to landfill is, indeed recyclable. This is partly because so many recycling plants are already operating at full capacity, or are governed by strict input / output quotients. Of course, despite what the governments of the world would have us believe, it is often cheaper to export waste to landfill sites abroad than it is to recycle it domestically.

Natural Resources are the primary trade items in the world.
Yes plastic do decompose. But they will take about 500 to do so. So we don't encourage to use plastic bags when we purchase our items in the supermarket. A better choice is to bring recycling bag , a recycling bag takes only a few years to decompose
Certain plastic bottles can be recycled and make other plastic items, so saving them from landfill.
Plastic bags, despite critical claims by ecological groups, do decompose. Originally the polyethylene in plastic grocery and garbage bags took a very long time to decompose (as other plastic items still do). However, the addition of various substances to the bags now causes the material to fragment, and it is then slowly broken down by natural processes. Early additives required sunlight (UV), but heat and moisture are now key to the degrading process.
The Sword Excalibur
Of the items on that list, radio has the longest wavelength and x-rays have the shortest.
Depends on the conditions it is kept in. I have seen leather items that are 5,000 years old.
