Sustainability is very, or even more important. Thats why I started to follow this thread. Not to buy things cheap or on discount.
I have often thought about the title of this thread, frugal and sustainable tips. Most of my posts here have been on saving money, the frugal part of the topic. I would love to hear more sustainable ideas on this thread, too. But it's only as good as members who want to post their sustainability ideas.
I have created a thread called
Show Me Your Pallet Projects which offers lots of ideas on how to reuse pallets to make things. I personally have posted a number of ideas on how to use pallets to make things like raised beds, trellises, and compost bins. At one time, all those things I have had purchased in plastic, but now use pallet wood instead. I guess that would fall under the sustainability category. I have saved a lot of pallets from the landfill, and that gives me a feeling of doing a small part to make things better for everyone. Also, using pallet wood instead of plastic is something I am willing to do in many projects.
Therefore I try to use very few plastic products and disposable products. Unfortunately there are often no alternatives.

Well, sometimes plastic is just the better option. I just would like to see better recycle programs for used plastic. Or, maybe a better plastic that could be recycled at a lower cost than making new stuff from new plastic. From many things I have read, it costs more to recycle plastic than just to make new plastic stuff.

Personally, I am not willing to pay more for recycled plastic products compared to new plastic products. I don't want to support a system that pumps out bad products for the environment. Paying more for recycled plastic products, to me, is still supporting the plastic industry. Better if we can find alternatives to plastic in the first place.

I would suggest using more glass instead of plastic, but I still remember growing up in the 1960's and having broken glass bottles and jars all over the place. That was no good, either.
I would love to cut way down on the plastic in my life.
Me too. Problem is plastic certainly does have advantages.
One small thing I do with some of my plastic jars, like peanut butter jars, for example, is to repurpose them as storage containers for small parts, nuts and bolts, nails and screws, etc.. out in the garage. Plastic is better for me in the garage because if I drop the plastic jar, it will not shatter like glass jars.
I repurpose those plastic jars for use in the garage. They are also excellent for holding parts that I might want to toss into a tool bag. Keeps them all together in one nice container. I use the smaller plastic jars for the tool bags. I have taken some of the larger jars and fastened the lid in an overhead place with a screw. Then I can just screw the jar into the lid. It's one small way to space in a small garage...

Back in the day, grandpa used glass bottles for storage like that. Plastic is better for this use. Might as well repurpose those plastic jars for use in the garage. IMHO, it's better to reuse them before recycling.
Not my thing, but those plastic jars are great for arts and crafts...
To make a hanging jar, you can drill a couple of holes in the jar lid and use a zip tie to make a handle. I can't find a picture of a zip tie handle, but it would look like this metal handle, only using a zip tie...
I have used that idea on a few things. The zip tie actually makes a better handle for hanging things on a hook, nail, or screw because the zip tie is flexible.
We also repurpose some plastic food containers, like whipping cream bowls, to use for leftovers in the fridge. We use those plastic containers until they break, crack, or maybe get stained and just look "dirty" at that point.
One of my favorite repurposed plastic food containers is the Great Value sliced ham we get at
WalMart...
That paper label on top comes off and you can see through the lid. Those plastic containers stack great in the refrigerator. They also are more space efficient compared to a round container. All I do is keep a roll of masking tape handy, along with a Sharpie marking pen, to write the labels and dates on the leftovers. Eventually, the lid will crack, or the bottom might break, but we usually get a few years out of them before they get sent to the recycle bin.
Yeah, I try to reduce the amount of plastic in my life, but I have found some good repurposing uses for some of the plastics we do buy. I think that might fall under the category of sustainable tips and tricks. I certainly don't spend extra money for plastic containers that I can reuse or repurpose.

Would love to hear what other people are doing to keep things out of the landfill.
