Crushed clean, dry eggshells, when scattered over the soil, are intended to stop adult gnats from laying eggs and potentially add natural fertilizer. However, they merely sit on the surface, collecting dust, while the gnats remain attracted to the damp compost.
Korea Zinc, which it described as one of the world's largest smelters, is in talks with major US technology firms to recycle data center waste and extract rare earth. The move comes almost one year to the day after China announced immediate export controls on seven more rare earth elements critical to enterprise IT hardware manufacturing.
Never place batteries of any type in your curbside recycling bin. Batteries can damage recycling equipment and, if lithium batteries are mixed in, cause fires. Always use designated battery collection programs.
Amazon's data centers will reportedly utilize copper from a mine in Arizona that's leaching metal from ores using microorganisms, the Wall Street Journal reports. Amazon Web Services will be the first customer for Nuton Technologies, which developed the "bioleaching" technology. AWS will also be providing "cloud-based data and analytics support," helping to optimize Nuton's mining process. Nuton's bioleaching method uses naturally-occurring microorganisms to extract copper from low-grade ore that would otherwise be too expensive to mine,
People grow asparagus from crowns because it shortens the long wait times for harvesting. From seed, you'll need to wait three years before harvesting asparagus. Some people consider that a waste of time. The tradeoff is that you can keep harvesting every spring for up to 15 years or more. If you plant crowns, you get a one-year jump on things. However, those crowns may have soil-borne diseases you don't know about, so there is a risk involved. Seeds remove that problem.
As concepts such as "regenerative" and "biodynamic" continue to enter the mainstream coffee lexicon, scientists continue to literally dig into the soil to give them meaning. A recent peer-reviewed study from India's Western Ghats argues that one of the clearest signals of healthy, sustainable coffee farms lies in the ground itself, with organic coffee soils performing better than soils from conventional farms treated with synthetic inputs.
You are not alone: social media is full of claims that soaking banana skins in water makes a fertiliser that will give you bigger leaves and better blooms.
