Nylon items such as tights and wind-cheaters, carpet, disposable nappies - although some think these could last 500 years, depending on conditions. This is made with refined petroleum and it is not easily decomposed - the natural micro-organisms in soil don’t recognise the chemicals as food, so don’t break them down. Many newer bags are designed to decompose when exposed to sunlight, though the majority are made from high-density polyethylene. Plastic bags, but a few studies suggest these can sometimes last for around 1,000 years. Heavy woollen clothing such as overcoats. Keen gardeners should bear in mind that cardboard can be composted, so don’t necessarily chuck it out.ĥ0 years: Tin cans, car tyres, trainers, foam coffee cups, leather - but leather that has been chemically treated, as it is for most fashion items, can last far longerĬigarettes contain more than 600 ingredients, of which the longest lasting is cellulose acetate - a plastic found in 95 per cent of cigarette filters - which takes a very long time to biodegrade. With such items, the decomposition time will vary enormously depending on the thickness of the carton. Waxed milk and fruit juice cartons, cardboard. Just because it’s natural doesn’t mean it’s not litter.

And banana skins can take far longer than this to decompose if the weather is cool.Īs the skins are designed to protect the fruit inside, they are full of cellulose, the same material from which cellophane wrappers are made.Įarlier this year, conservationists warned that Ben Nevis was being blighted by discarded fruit peels including banana skins, which were taking months to decompose. Toilet paper put into the ground actually takes far longer to decompose than if it is exposed to the elements.Ĭereal boxes, paper bags, banana skins.
With these items, decomposition time can vary enormously depending on how they are disposed of.
Paper towels, paper bags, newspapers, tissues. Although this is a rapid decomposition time, throwing away cores and other pieces of fruit encourages scavengers such as rats, which are seldom welcome anywhere. It’s not just man-made items - even banana skins can hang around for more than a month, while orange peel can take up to two years to fully disintegrateĪpple cores.
