Our new furry food-processing unit is settling in well – she’s curled up in a ball on our office sofa at the moment – and we’ve been enjoying the woodland walks with her now that she can go off lead and tire herself out.

As with the cats, I’m trying to keep the waste produced by her food packaging to a minimum – and also, like with the cats’, it can mostly be recycled – cans, cardboard boxes and the giant paper sacks which are the focus of this post.

I bulk-bought the 15kg bags to save money and reduce packaging – but thought that, like with smaller bags of the same brand, the big bags would be plastic so could be reused as rubble sacks or similar in the garden. They turned out to be paper which is better in some ways – much easier to recycle – but less reusable. Or are they?

They’re a double layer arrangement – brown paper on the inside, shiny printed paper on the outside. The brown paper layer smells somewhat of dry dog food so can’t be reused for things I’d ordinarily reuse brown paper for (packaging items to post etc).

So any ideas?

We’ve had an email from Alana:

The kibble I get my dog has switched from being in paper bags to plastic ones. What can I do with them now?

You may still be able to recycle them – the plastic cat food bags we’ve got are labelled as recyclable (although not actually saying what type of plastic they are, just that “most councils accept them for recycling” – a great example of the unhelpful lack of information that Simon was complaining about the other day – I suspect they’ll be LDPE, ie number 4 plastic). Check the packaging for similar (although hopefully more helpful) recycling marks.

As for reuses, they’re pretty strong plastic and sometimes with a zip lock seal at the top so can be used for a range of airtight/waterproof storage purposes. An idea for smaller bags might be to decant washing powder from cardboard boxes into the bags to stop it absorbing moisture from the atmosphere. Bigger, dog food size bags, could be used in the garden – a seasonal idea might be to use them for leaf mulch. Staying in the garden, the bags could also be sliced open to use as plastic sheeting to protect crops over winter/discourage weed growth (although with the usual caveat that plastic that isn’t specifically designed for outdoor use tends to break down in the sunshine).

Other ideas?
