#reducereuserecycle

2 posts2 participants1 post today

Curious how this goes. I seem to live in the same top-level postal code (K2G) as the #oddBunch people, and their veg delivery boxes are collecting in my garage.

They already re-use cardboard boxes - they're always labelled as chocolate bars and candies, presumably from some candy distributor.

I hope I can drop my collection of 15 or 20 boxes off for another go-around rather than send them to recycling.

New year, new flat, new techniques for new projects.

I learned some rag rug braiding because I desperately needed a doormat. You see: there’s quite a bit of snow (unprecedented in Scandinavia, I know) and my floors need protection.

A perfect stash busting first attempt. I also filmed the process and will be publishing a tutorial. Some day….

Today’s magical (free!) recycling station find: a Weber Q2000 gas grill!

We’ve been talking about getting a gas grill as we’re not allowed coal bbqs in the building, and our electrical one is great, but only serves 2-3 people which isn’t enough when we have guests… and this one looks to be in good shape! And even if something isn’t working I’m sure it can be fixed for less than the cost of a new one!

Hey, looking for buying advice/recommendations on a replacement subwoofer for a home audio system. I had a cerwin Vega 12" sub, but I think design /manufacturing flaws gave it a minimized lifespan (Short on the LFE and an internal resistor component fired the board). I would like something of a similar range but I'm not an audiophile here and can't pretend to hear "magic levels" especially in bass. boost for reach appreciated.

Alternatively any body know of someone that repairs audio equipment in the Ottawa area?

Hab eine kleiner Tour durch #Bremen #Neustadt gemacht, um neue Geschäfte erkunden:

1. Recyling-Börse (Lahnstraße 106; recyclingboerse-bremen.de/Shop): viele Bücher, auch Kleidung und Haushaltssachen und sowas. Und ich hab sogar was gefunden, was ich evtl. schon länger gesucht hab (einen Tupperware Quick-Chef). Für 5 € ist der einen Versuch wert.

Better ways to recover metals needed for technology from #ElectronicWaste could benefit the #environment and human health

Published: December 3, 2024

"As if our tech consumption hadn’t pushed demand for these metals through the roof in recent years, COVID also helped to make it worse. The pandemic drove sales of new electronics, contributing to more waste as old equipment became obsolete. The change to work-from-home/hybrid working saw more purchases of laptops and mobile phones. People also saw the pandemic as an opportunity to upgrade their televisions and games consoles.

"This has made it all the more important to recover the crucial materials we need from e-waste. One response has been from the Royal Mint, which has opened a recycling plant to recover 450kg of gold from 4,000 tonnes of e-waste per year – potentially enough for around 13 million phones. The average smartphone contains around 34mg of gold, which accounts for over 60% of the value of the metal-based parts of the phone per device.

"The Royal Mint initiative is an important milestone towards adopting a greener approach to metal recovery from discarded hardware. The mint is using an ambient temperature process, which means that precious metals can be recovered at room temperatures rather than being sent to smelters. The same process also allows for the selective recovery of other metals from the waste, such as palladium, silver, copper, iron, steel and aluminium.

Toxic methods

"The Royal Mint initiative is important because the recovery of technology-critical metals from recycled electronics typically employs much harsher conditions. Waste electronics generally first undergo what’s called pyrometallurgy, the extraction and purification of metals involving the application of heat in a smelter. This is done to liberate the metals from their casings.

"Further purification – both for the Royal Mint and other recovery processes – is carried out using methods collectively known as hydrometallurgy. This uses water-based solutions to recover purer forms of the metal, but also produces harmful waste: strong acids, such as sulphuric acid or nitric acid, as well as a group of chemicals called lixiviants, which can include cyanides, may be used to dissolve materials.

"Further treatment is required before these substances can be safely discharged back into the environment. Not doing so risks significant environmental impacts like the reported 'cancer villages' in China, which some have linked to factories and polluted waterways.

"Also environmentally troublesome is what’s known as artisanal, or small-scale, #mining – involving individuals, groups or co-operatives, rather than corporations. This accounts for 12%-15% of the global mined gold supply, accounting for around 2,000 tonnes per year.

"This mining occurs in over 70 different countries. The UN Environmental Programme estimates that artisanal and small-scale mining involve 10 to 15 million miners globally, including 4 to 5 million women and children.

"The cheapest and simplest method of extracting gold from ores, as well as from waste electronics, involves using mercury. This involves boiling off the mercury, releasing toxic mercury vapour into the environment. This can significantly reduce the life expectancies of people exposed to the resulting pollution, as well as causing significant damage to local water-sources and to soil.

"The opening of the metal recycling plant by the Royal Mint is therefore beneficial for various reasons besides being relatively environmentally friendly. It will lead to fewer toxic metals going to landfill that could potentially leach out into water supplies, and it will reduce our reliance on artisanal and small-scale mining for gold, reducing pollution and the risk to human health."

16 places to responsibly dispose of old #electronics in #Philadelphia

When not properly recycled, #Ewaste can leach into the waterways — and we miss a chance to get more use out of precious materials.

"For many Philadelphians, old #CellPhones, #laptops and other #electronics gather dust in drawers or boxes in the back of closets.

"When residents finally start to feel fed up with the clutter or during their annual spring cleanings, these devices are sometimes tossed into the trash or blue recycling bins. These forgotten electronics have become a part of a growing citywide e-waste problem.

"Philadelphia creates around 1.5 million tons of residential and commercial waste annually, according to government initiative SmartCityPHL. Electronics and textiles comprise about 10% of the city’s waste stream. The rest is sent to incinerators and landfills, bringing hazardous and resource-rich materials with it.

"But the good news is, there’s something residents can do about it.

"While giving up or not upgrading our devices isn’t always an option, getting them out of our curbside bins and landfills is. The Philadelphia metro region has over a dozen facilities where you can donate and properly recycle your e-waste, keeping them out of landfills and giving them new life.

Here’s a guide to places in the Philadelphia region to responsibly dispose of old electronics."
