LaMa separates the gel problem from the plastic recycling stream
Superabsorbents complicate wet processing; reported 200 kg/hour operation does not establish a route for every used diaper or construction mat.
Explainers, teardowns, and myth-busting on waste management systems and green engineering.

Superabsorbents complicate wet processing; reported 200 kg/hour operation does not establish a route for every used diaper or construction mat.

Bio-based content and deliberate chain cleavage change material design; fragments are not yet proof of a closed recycling loop.

Sulfur-bearing binding sites work beyond water, but removal efficiency is not yet a closed metal-and-solvent recycling loop.

Reactivating demolition cement in an electric arc furnace uses existing infrastructure, but feedstock, standards and carbon boundaries still matter.

The expanded system links recovery with carbon removal, but operating sorting capacity is not operating biochar capacity.

Cleanliness, item size and local sorting rules decide whether household foil has a real recovery route.

An electrochemical bath preserves electrode structure, but coin-cell recovery is not yet a pack-scale recycling service.

Fast depolymerisation is not the same as fast textile recycling; sorting, purification and future plant operation determine the result.

Reported allegations involving appliance companies reveal why invoices, recycling certificates and physical processing need separate verification.

A nanosecond-laser process recovers silicon and silver from old panels at 97% rates and very high purity. The open questions are panels per hour and cracked real-world modules.

Meta will buy environmental attribute credits from MacroCycle's solvent-based PET recycling. The chemistry is novel. The plant does not exist yet, and Meta is not buying any recycled material.

BRIN is assembling AI sorting, gasification, plastic-to-nanotube conversion at 1,600 °C and calcium looping into one pipeline. Here is the chemistry of each stage and how much of it exists.

Greyparrot's cameras say 89% of aluminium passing a Brooklyn MRF is recoverable. That is a measurement of loss, not an improvement in recovery — the pilots that would show that have not run yet.

The End-of-Life Vehicles Regulation mandates 15% recycled plastic from 2032 and 25% from 2036. To see why that is difficult, follow a car through the shredder.

A Basel Action Network investigation found eight of ten U.S. firms shipping e-waste to Southeast Asia held R2v3 'responsible recycling' certification. Here is where drop-off electronics can really end up.

The French startup claims +45% yield, −60% energy and −45% cost by heating a catalyst with induction to turn plastic waste into olefins. Every figure is self-reported, and none has a baseline.

Cartons up 61%, mixed paper down 34%, plastics now outweigh paper in U.S. recycling. The new report is the best picture of the bin we have — and says almost nothing about what to do.

From October 1, Alberta charges $14 on every new panel and bans end-of-life panels from landfill. Here is how a panel is taken apart, and why the fee is already contested.

Thermal receipt paper carries a bisphenol coating. Put it in the paper stream and the chemistry ends up in recycled paper products.

The US generates roughly 800,000 tons of recoverable polyethylene film a year. Twenty-seven reclaimers can process it, and fewer than half will take household film.

The first carpet EPR programme in the US now runs 174 drop-off sites and recycles 78.5 million pounds a year. It is also a lesson in how slowly EPR moves.

Separating polyester from cotton is textile recycling's central unsolved problem. Worn Again's Swiss facility has module one commissioned and module two on paper.

pDCPD is a cross-linked thermoset with no recycling route. A ruthenium catalyst and a stirred solvent take it apart - and leave the carbon fibre intact.

Most recycling programmes reject loose shredded paper, and the reason is mechanical: the strips are the wrong size for the machines that sort paper.

On-site shredding and disinfection that turns regulated medical waste into recyclable polymer flake. The disinfection is certified. Most of the headline numbers are not.

For decades half of Quebec's curbside glass was buried as landfill cover. A $20M optical-sorting upgrade finally gets it clean enough for the furnace.

Two reverse vending machines in Dokki pay phone credit for bottles and cans — the exact fraction that has funded an informal collection economy for a century.

Four companies, six steps, and one link where the recycled content is attributed rather than physically traced. The pyrolysis is real. The loop is partly bookkeeping.

A hot-drink cup is about 95% paperboard. The other 5% is a polyethylene liner, and that 5% is why most mills reject the cup outright — even when you put it in the right bin.

Near-infrared sorters are blind to black plastic and confused by multilayer film. Terahertz sensing sees through both. The physics is real; the belt speed and the detector price are not there yet.

Recovering neodymium and dysprosium from used magnets has been technically demonstrated many times over. Almost none of it happens, and the reason has nothing to do with metallurgy.

Chemical recycling of PET normally means a stirred tank and several hours. Kirin and JSW have moved the reaction into a continuous extruder. If the numbers hold, the interesting part is throughput per unit of capital.

Certified compostable packaging is engineered to break down in a hot industrial windrow. Put it in a garden bin, a recycling bin or a landfill and it behaves like ordinary plastic — because in those conditions, it is.

R3 Lithium is taking over battery recycling capacity in Covington, Georgia that Ascend Elements spent far more to build. The asset is real. The question is whether the funding matches what refining lithium to spec actually costs.

An EU project says it has closed the loop on PLA — sorting, depolymerising and repolymerising bioplastic back to virgin-grade. The chemistry is sound. The numbers that decide whether it matters are missing.

Chemical depolymerisation of nylon 6 back to caprolactam is proven chemistry with decades of industrial history. The constraint has always been that most nylon in the world is blended into textiles that cannot be separated.

Crushed concrete reacts with CO2 to form calcium carbonate. Done deliberately, that upgrades recycled aggregate and stores a modest amount of carbon — and the modest part is where most reporting goes wrong.

Glass really can be melted and remade forever without losing quality. About a third of it in the US actually is. The gap between those two sentences is the entire story.

Rice University reports ~95% recovery of critical metals using citric acid. The chemistry is genuinely clever. The framing around it — the lemon, the 10% figure, the record — does not survive a close read.

Mass balance accounting lets a producer allocate recycled input to selected outputs. The molecules are real somewhere in the plant. They are not necessarily in the product carrying the label.

PMMA depolymerises back to its own monomer at high yield with nothing more exotic than heat. It is the clearest existing example of true chemical recycling — and the reason it stays rare is collection, not chemistry.

A pilot plant recovering lithium without mineral acid is a genuine contribution. The gap between pilot tonnage and the volume of batteries reaching end of life this decade is three orders of magnitude.

Conventional battery recycling dissolves cathodes in hot mineral acid. Microwave-assisted leaching in a deep eutectic solvent does the same job at lower temperature, in minutes, with a solvent you can in principle reuse.

Flexible film and black plastic defeat the two technologies a modern sorting plant relies on. A Finnish process uses density and water instead — and a 50,000-tonne plant is being built around it.

Conventional PET recycling wants clean, clear, single-stream bottles. Oak Ridge built a catalyst-free route that takes the contaminated stuff and splits it into two high-value materials instead of low-grade flake.

Shredders mix steel rivets into aluminium body sheet, and iron makes recycled aluminium brittle. ORNL's answer was not to purify the scrap but to design an alloy that tolerates the contamination — found by screening two million calculations and verified with neutrons.

The EPA's guidance is the exact opposite sentence. One in four items in the bin is contamination, it costs the system $300 million a year, and the doubtful item does not get rescued by the machine.

Nth Cycle took $100M and Princeton NuEnergy $50M out of the DOE's $500M battery round. Both have operating plants and third-party numbers — which is more than most. Neither has solved the part a grant cannot buy: feedstock.

A Surrey team made a polyethylene-like polymer that turns to vapour at around 90 °C and condenses back into the same solid. The mechanism is elegant. The distance between it and a recycling system is the whole story.

Two doorbell videos show recycling carts going into a garbage truck. That is real evidence of a service failure — and not evidence that recycling is fake. The gap between those two statements is where the actual records live.

A donation bin is a sorting decision, not a disposal guarantee. Wearable, repairable, rag-grade and unusable all go different places — and the condition of what you put in decides which.

Covestro is backing BioBTX to build a commercial plant in Delfzijl that turns hard-to-recycle plastic into benzene, toluene and xylene. The chemistry is straightforward. The evidence is a construction schedule.

A molecular-recycling company and a major polyester producer have agreed to work together. The announcement contains a number measured in billions of pounds. It also contains no obligation to build a plant, process a tonne, or license anything.

Laboratory plastic is regulated waste before it is a material. A new on-site system shreds, disinfects and dewaters it where it is generated, so what leaves the building is polymer flake rather than a hazard consignment. The step from flake to product is the one still missing.

On 19 August the U.S. Plastics Pact removed expanded-polystyrene transport packaging from its Problematic and Unnecessary Materials list, citing a recycling rate above 30%. That is a real result on a narrow slice of foam — and it is not permission to put your foam cup in the recycling bin.

Carbon-fibre epoxy composites are among the hardest materials to recycle, because the resin will not melt back. A team at NUS skips fibre recovery entirely and turns the whole waste stream — fibre and epoxy together — into a freeze-dried porous block.

Bags, wraps and mailers are plastic, carry resin codes, and look recyclable. They are also one of the most reliable ways to shut down a sorting line.

End-of-life tyres go into a pyrolysis reactor; a certified share of recycled feedstock comes out attributed to a tin of interior paint. The chemistry is real, the audit is real, and the word doing the most work is "attributed".

Recycling has become the default green answer, which quietly skips two better options sitting above it. The waste hierarchy is not a slogan — it is a ranking, and it puts reuse first for a specific reason.

Iron-and-phosphate cathodes are cheap, which is exactly why conventional recycling struggles to pay for them. Direct regeneration takes a different route: repair the cathode powder instead of breaking it back down into salts.

Paper is one of recycling's genuine success stories — 68.2% recovery, the largest modelled share of MSW greenhouse-gas reduction. It is also finite at the fibre level. The loop is a cascade, not a circle.

A UK startup just raised £700,000 to pull aluminium and iron treatment chemicals back out of water-plant sludge. It is a good excuse to explain a circular loop most people never see: the chemicals that clean water can themselves be recovered.

A tumbler and a jam jar look like the same material. To a container-glass furnace they are not. Here is why household glass collection is built around bottles and jars specifically — and what to do with everything else.

A polyethylene core-sheath yarn that stretches like PET-spandex and survives ten melt-and-respin cycles. The material result is real. The gap between a recyclable yarn and a recyclable garment is where almost all of the difficulty still sits.

CP Group's Sentry pairs X-ray with RGB cameras and AI to spot batteries and propane cylinders on a moving recycling line. Circular Services is installing it now — here is how the detection zone works, and which numbers nobody has published yet.

Collection trucks and sorting lines are visibly energy-hungry, which makes the myth feel obvious. EPA's own numbers say otherwise for most materials — but the word doing the damage in the myth is "always", and it cuts both ways.

SABIC has launched a carbon-fibre-reinforced polycarbonate with more than 75% post-consumer recycled content, made from water bottles, CDs, golf shafts and turbine blades. The materials engineering is real. The circularity claim is doing more work than the data supports.

Grease alone is not a disqualifier for a pizza box — EPA says recycle it. Loose food, liners and your local programme's rules are the parts that actually decide.

Divert and US Cold Storage say 2.5 million pounds of unsold food became renewable natural gas and fertiliser in 15 months. The operating facts are solid. The carbon accounting behind them is not published.

Metals and glass survive remelting largely intact. Polymers do not. Every mechanical loop shortens chains, and the recycling symbol says nothing about how many loops a package will realistically get.

A 50/50 e-waste venture between a large US recycler and a Vietnamese environmental-services group has real operational strengths. What it does not yet have is a plant, a permit, a mass balance or a named downstream buyer.

A sorting facility separates materials. It does not run a dishwasher. Here is what "empty and rinsed" actually means, why food-soiled items cause real damage, and where over-cleaning becomes its own problem.

54.1% recovered. 89.5% recycled content. Both figures are real, both come from the same 10 August study, and they measure different things. Separating them changes what the numbers say about household recycling.

Abu Dhabi is building a 400,000 tonne-a-year material recovery facility with optical sorting and AI. Here is what that machinery actually does to a conveyor belt of mixed waste - and what still falls off the end as residue.

A Ministry of the Environment-commissioned demonstration puts nine Japanese companies on a shared platform to delaminate and deink flexible packaging. It is a genuinely interesting infrastructure model. It is not yet proof of scale.

Energy recovery has a legitimate place in a waste system. It sits below prevention, reuse, recycling and composting - and roughly a tenth of what goes in still comes out as ash bound for landfill.

A battery that no longer powers your device still holds enough energy to start a fire when it is crushed in a collection truck or a sorting line. The recycling symbol on it does not mean curbside.

Q2 brought first branded resin deliveries, seven customer conversions and 173% revenue growth. It also brought a $142m net loss. A look at what advanced recycling has actually demonstrated, and what remains a forecast.

A US$25m financing deal for on-site solvent recycling is a good excuse to look at the mechanism itself: how heat, vapour and a condenser separate reusable solvent from everything else - and what the leftover still bottoms actually cost you.

A 33.5-year exclusive treatment concession, three combustion lines and roughly 1 TWh a year. The contracts are signed. The financing, the emissions baseline and the recycling question are not.

A compostable label describes how a product behaves under specified industrial conditions. It is not a promise that your compost heap, or your recycling bin, can handle it.

The chemistry is real. The label is doing a lot of work. If the outputs are hydrogen gas and mineral carbonate, no plastic has been recycled — something else has happened.

A new PNAS study converts mixed PET, PE and PP into >90% pure hydrogen in one reactor — no polymer sorting, and most of the carbon never reaches the gas phase.

China's second-life battery decision is being read as a win for the circular economy. Shredding a working battery to recover its metals is the opposite of the waste hierarchy.
