Hey VG. Regarding the paper shredder. I bought one years ago, when i had ideas of using all the kids’ old school paper and stuff. It took 5 x A4 pages at a time. I still have it and it still works. It’s just one of the regular varieties from BigW or whatever. Cost about $50 i guess.
However, you have to decide, is the electricity you use to shred the paper worth the end product? I doubt it. Shredded paper isn’t much good as mulch so if you want to compost it, better to just rip it to bits and scrunch it up a little. Maybe have a bucket to soak it in, possibly with a few drops of fish emulsion in it and every now and then empty the bucket into the composter.
For newspapers, it doesn’t work too well. I put them in the worm farm or in the compost. We also use them as fire starters.
Packaging is best avoided altogether where possible. That means buying fresh foods, not packaged or processed and where you have to buy stuff, try and get stuff in steel tins, cardboard boxes or in recyclable packaging. Avoiding plastic packaging where possible. SO if you need to buy potatoes, buy them loose and put them in your own, reusable bags.
Another idea is to get a rubbish bin for the kitchen which uses bread bags as a liner. If you have little packaging and recycle all your waste products, a bread bag is more than big enough for a days rubbish for the average family. The answer is not to buy more machines, which themselves are packaged in plastics and use energy, but to utilise what you have and minimise the waste products by recycling them.
