Shanghai Achieves 98% Industrial Recycling Rates After 2019 Waste Management Plan
A national waste management score of 100, Shanghai scored 86.9—the highest for a city of its size in the country. 

Under new European Union rules, businesses must prioritise keeping unsold clothing or shoes in use by selling them (including through discounts or alternative markets), donating them to charities or social enterprises, or preparing them for reuse (repairing, refurbishing or remanufacturing).
Destruction will be allowed only under specified circumstances and must be carried out in accordance with the waste treatment hierarchy, giving priority to recycling

Ban on destruction of unsold clothes and shoes enters into application
Under the new rules, businesses must prioritise keeping products in use by selling them or preparing them for reuse.

i'm reminded of when spinal tap released their reunion CD in an extra-big cardboard long-box so there was more to be recycled.

Italian researchers found a brilliant way to give old solar panels new life. They're extracting silicon from discarded panels and turning it into a high-performance catalyst using palladium nanoparticles.
The recycled material matched commercial catalysts across six cycles with 97% yield—tackling mounting solar waste while creating valuable chemistry tools.

Upcycling silicon from end-of-life solar modules via palladium nanoparticles
Researchers in Italy have developed a Pd/Si catalyst for upcycling silicon from end-of-life PV panels. The system showed performance comparable to commercial-silicon catalysts and stable recycling over six cycles.

«In alten Handys schlummert eine Tonne Gold:
In deutschen Schubladen lagern Millionen alte Handys – inklusive einer Tonne Gold und weiteren wertvollen Metallen. Doch kaum ein Gerät wird recycelt.»
So geht moderner wohlständige Verwahrlosung und dann sich wundern, dass deren Werkstoffgrundlage sich schleichend aber andauernd sich verteuert und deren Umwelschaden noch nicht angesprochen.

Junkyard Computing: Repurposing Discarded Smartphones to Minimize Carbon
1.5 billion smartphones are sold annually, and most are decommissioned less than two years later. Most of these unwanted smartphones are neither discarded nor recycled but languish in junk drawers and storage units. This computational stockpile represents a substantial wasted potential: modern smartphones have increasingly high-performance and energy-efficient processors, extensive networking capabilities, and a reliable built-in power supply. This project studies the ability to reuse smartphon…

This is the most detailed picture of a human cell ever made 🧪

Sam Bousaba on Instagram: "This is a single human cell. The white filament-like structures are microtubules, and the small colored particles are ribosomes. Your body contains on the order of ~37 trillion cells. Each cell functions like a highly organized, self-regulating factory operating continuously. There is no central “supervisor”—yet thousands of processes run in parallel with remarkable coordination. Every ribosome is constantly building proteins by linking amino acids together. In eukaryotic (human) cells, a ribosome typically adds about 5–10 amino acids per second (not ~20). Since a single cell can contain millions of ribosomes, protein production is massive—resulting in millions to tens of millions of peptide bonds formed per second per cell. The microtubules act as an internal transport network. Motor proteins such as kinesin move along these tracks, carrying cellular cargo. They “walk” step by step using ATP, at speeds of roughly 500–1000 nanometers per second. Each cell contains a dense network of these filaments, with many motor proteins moving simultaneously. Just beneath the cell membrane lies the actin cortex, a dynamic meshwork that helps maintain cell shape and resist mechanical stress. This structure is continuously remodeled—assembled and disassembled—allowing the cell to adapt to its environment. Now scale this up. Across ~37 trillion cells, each containing millions of ribosomes and hundreds to thousands of mitochondria, your body is constantly producing energy in the form of ATP. Total ATP turnover is enormous—roughly equivalent to your body weight in ATP recycled every day. The DNA in a single human cell, if stretched out, measures about 2 meters. Across all your cells, this would span distances comparable to traveling from Earth to the Sun and back many times (the exact multiple depends on assumptions about cell count and DNA packing). None of these processes are under conscious control. They began when you were a single cell and have continued uninterrupted ever since."

this is neat: 3d printing prototype injection moulds https://youtu.be/9LCIFetDKUA
they don’t work well but they’re good enough to cheaply try out a mould design
the desktop injection moulding machine is pretty swish too: the idea is to use it for plastic recycling

A lot of 'recycled' plastic is being burned overseas—and causing widespread pollution linked to health problems
Picture a pile of trash the size of Manhattan and taller than one and a half Empire State Buildings. That's how much plastic waste the world is predicted to be generating every year by 2050 if nothing is done to change course.
