Apparently a lot can be done. Fridge triage boxes look like a good idea: Tracking what's inside the fridge with dry-erase decals also seem good, but probably takes a lot of time to manage properly. Keeping your fridge uncluttered is definitely good. Grouping similar food types together in a refrigerator to increase the awareness of available foods has ...

Technical terms To partially understand the process of draining batteries it is important to know some technical parameters: voltage - Battery operated electric devices need certain minimal voltage level and current to work correctly. As a battery is being drained the voltage drops down. In some batteries the voltage goes down very slowly during most of ...

So I’ve just put a system in place for this, it appears to be working okay. My plan was to reduce the amount of food that goes bad in the fridge, and, as a secondary goal, to eat a wider variety of foods and make sure that I washed up after myself and so on. What makes this easy is that I have a favourite pan, I do pretty much all my cooking in my favourite ...

Yes, using a menstrual cup (such as DivaCup) is much better for the environment. I located a thesis paper written by a student at Dalhousie University for her BSc in Environmental Science and Gender and Women Studies which compares the financial and environmental costs of various menstrual products. Here's the relevant part of the abstract: The ...

Here is what I do. I throw very little away if I am managing the food. This can keep waste down well below what people consider waste. It takes some trial and error to get right (no onion skins can't go in the stock bag and neither can squash skins), and those can be costly in terms of throwing stuff away but once you get it, this leads to hyper-...

​​Yes, blister packs are recyclable (for example with machines like this one) but chances are there's no recycling company in your area that will accept and recycle it unless you are able to separate the different materials yourself. Blister packs like the one you posted typically consist of plastic (usually PET or PVC) and aluminium. The problem with ...

It is. However, the aerobic process of composting produces CO2, which is better than the anaerobic processes which result from burying compostable materials under layers of sand (preventing access to air), such that it creates methane. If the methane isn't captured (and in most landfills on earth, it still is not) then it causes climate change at a rate of ...

You don't need a perfect seal in the microwave - in fact the reason your plastic wrap doesn't explode is that the seal isn't perfect. So placing a plate or saucer on top of your microwave container (depending on the size of the container underneath) works very well without you needing to buy anything extra. It might get hot from the steam, or drop hot water ...

I've rebuilt two single-battery operated appliances in our home to a "battery juicer". I'll describe one of them here to explain the idea, the other one is remade in a similar way to this one. Both of them operate happily with half-drained batteries and I've reached the balance of incoming half-drained batteries and draining them almost totally in those ...

You are talking about black gold that has a value of AU$40 per 25 litre bag in my area. I would suggest either selling it or putting it back into the soil. See https://en.wikipedia.org/wiki/Biochar for uses of charcoal as a soil amendment. You can collect (cool) charcoal in a plastic bag until you have a volume worth doing something serious with. Because ...

Does anyone use wood wool anymore? It's all peanuts and bubbles now a days. Wood wool depends on pulling long shavings with the grain. If you cut across the grain, the strand will break on a growth ring. With scraps, I think it would be hard to maintain the orientation of the scrap to the strand knives. Successive layers of wood have grain at right ...

While you may not be able to get them refilled yourself, HP does run a recycling program for them, free of charge: HP Product Return and Recycling. Didn't look in to whether they simply refill and resell them or if they actually melt the cartridges down and start from scratch... either way it's better than the landfill. Unfortunately, you're still stuck ...

I think Western kitchens have a much different focus on foods, as well. Meat is often the center of many meals, for instance. I find efficiently storing (freezing, thawing, cooking, storing prepared meat) to be difficult to manage without waste. Your choice of foods can dramatically decrease your waste. I recommend using more curries (stored as curry ...

The report provides only raw numbers, without the information about the particular reasons for throwing food away. But according to my knowledge about patterns promoted in the media and observations of my acquaintances, only a small part of it is the food that is actually spoiled. Most of that is thrown away because the expiry date is reached, someone has ...

It's reasonable to say that a lifestyle can still be sustainable even if not everybody could live that way. It's like filling a niche in an ecosystem. Obviously we can't all eat discarded/excess meals, but there is certainly room for such behaviour to be part of a system that is sustainable as a whole. You almost certainly can't live that way your whole life ...

Depends on the type of cloth. Natural fibres such as cotton and wool often make sustainable materials, especially if they are certified organic as this adds a greater level of sustainability to the product. Wiping cloths for babies can be washed by hand to reduce the water use and increase the sustainability of its usage rather than using a washing machine. ...

You have to also consider the climate where each type of cooler will be used and how each type of cooler works. Refrigeration coolers transfer heat from inside a building to the outside. However, the hotter the outside temperature the less effectively such coolers work. If the outside/atmospheric temperature is 50 C or higher, such coolers will struggle. ...

My better half found a set of silicone lids. Three in the set, about 6, 8 and 10 inches across. They are heavy enough to stay put, and make a reasonable seal, an sticky enough that they don't slide. Rinse after use, and leave by the microwave. Another option: I've seen a cake cover type thing with a single 3/8" hole near the top. Place it over an open ...

I know of one independent place that happily refills the containers they use, if you bring them back clean. In this case the container is used as a portion measure so it wouldn't work with arbitrary dishes. In this case they were the typical plastic takeaway boxes (amazon link). A couple of my colleagues did this; I didn't as I could dishwash and reuse ...

The problem with burying plastic in landfills is that plastic takes ~500 years to decompose, and burying large amounts of waste leads to groundwater pollution in the surrounding areas, which is difficult to solve. Reducing or eliminating plastic will help landfills in the long run because we cannot keep dumping our waste plastic in landfills, it will reach ...

My solution is meal planning. I found there were three reasons I was throwing food away: it was leftovers that I didn't get around to eating because I had made a meal when there were already leftovers in the fridge, until there was just too much to eat before it was too old to eat it was a raw ingredient that I had bought on a whim, that spoiled while I ...

Almost certainly the 200g containers. Imagine a cube of yoghurt (ugh!). Think about the amount of material that will required to fully encompass that cube. That is the 1kg container. Now imagine that that cube is partitioned into five parts, and think about the amount of additional material required to accomplish this. That is 5x 200g containers. The only ...

There are blister packs which appear to be made entirely from aluminium and I put these in the recycle bin in their entirety. I have also been recycling the blister packs made from plastic and aluminium. I do this by occasionally separating the aluminium from the plastic in a sort of game of 'patients' by trying to separate as much of the aluminium from the ...

No, it's not sustainable. As per your comment, you're not doing anything economically productive, but you are consuming goods and services. It doesn't matter that those goods and services are free to you at the point of consumption - what matters it the consumption itself, which is happening without you contributing to economic replenishment. That's not ...

The problem with PLA-based plastic is that it requires high temperatures and moist conditions for a relatively long period to actually degrade and turn into compost. Theoretically it is possible to compost it along with all other compostables (food leftovers, garden wastes), but PLA takes much longer to fully decompose than 'normal' organic waste and it ...

Simon W is overall correct. While when the size gets large enough the walls have to be thicker because of the weight involved, for small products, the problem is that they have to be strong enough for the handling machinery. However there is an easy way to test this: Weigh them. Empty of course. For each container wash it and weigh it. Don't forget the ...

If you have fruits like Strawberries, Mangos, Bananas, put them in the freezer before they go bad. You can use them to make delicious Milk Shakes and Fruit Smoothies any time.

I have been using a CISS (Continuous Ink Supply System) for some time on my Epson RX610. Purchased through eBay it is a cheap investment. Be aware of the following regarding inks: the most important part of the whole printing system is really the quality of the inks and not so much the hardware Occasionally the printer "Cannot recognise" the non-genuine ink ...

There are some printers which are compatible with a Continuous Ink System. Today I bought one of these for my printer, so I can't tell you right know if this system works or not. I don't want to make publicity for a particular product, but I think if you google a bit you will find some stores and see in which printers this can be used.
