One of our old carpets has been out in the garden for ages surpressing weeds. It’s going to be used again soon as an underlay for our pond liner.

I would think that synthetic carpets are not ideal for the garden as they will never rot down and the foam backing will break down and get everywhere.

If only part of the carpet is ruined, you could use the decent parts to make rugs and runners for around the house.

wrap the compost box with old carpet to keep it warm!!!

Staple or nail it to the sides of sofas for cats to scratch. You’ll probably need an electric power stapler.

Screw it to walls too.

I’ve got a couple of layers of old carpet on the floor in my greenhouse - it means things aren’t sitting directly on the concrete floor which gets very cold in the winter. It does mean I have to be more careful when watering though.

You can use the best bits for a welcoming mat at you front door.

Or if too good for that then why not offer it on recyle web site for someone else to use it. You can find one through out UK.

Here is the link http://www.freecycle.org/

Hope this helps some.

Wrap it tightly around a cardboard roll or block of wood. Then give it to your cat. They like to scratch things, and this will prevent them from shredding up your sofa.

Tape it to tile floors in the winter - save your feet from the cold and maybe save some heat as well.

What I have done/doing in an on-going project is makeing indoor rugs out of the old but good carpet round our house.
I take the best pieces and make a center rug. say maybe a 5×7 size. then I add the other carpet pieces or runners around the main rug and attach each long piece with the strong carpet tape found at hardware stores.This is stronger than duck tape. Of course all the tapeing is done on the back side so the tapy will not be seen. From the top side it looks just like a fancy designer rug. to bind the edges, cut up canves paint drop cloths that are cut in long strips andeither died to match the carpet or can be painted to match. You attach the binding with the glue gun by first glueing on the front side and turning the edge under as you go and than glue the bottom side. I use a glue gun.you don’t even have to make the bottom look good just glue it down to stay put. We not only made a wonder rug for under the dining table but even put a round circle out of the contrasting carpet piece in the center and it all looks like an asian rug. It looks very expencive. janet

Carpet burns is a Derby (UK) based company that reuse polypropylene based carpet waste, creating innovative products. www.carpet-burns.com

An animal shelter I know of uses 1 foot square pieces of carpeting to put in the cat cages. Maybe check out your local shelter.
