Every year the world pulls 106 billion tonnes out of the Earth. This much of it comes back around:

The most successful circular material on Earth, largely unnoticed. Around 1.89 Gt of crude steel a year, with roughly 630–680 Mt of scrap consumed annually. Construction steel recovery exceeds 85% in mature markets.

Electric arc furnaces run near 29% of global output — but only ~10% in China, which makes over half the world's steel. China's 2000s building boom is only now becoming scrap.

Scrap becomes both the constraint and the prize. The hidden ceiling is copper contamination from shredded vehicles and appliances. Investment case: sorting and de-tramping, not new furnaces.

Recycled metal settled at roughly a third of global supply. Remelting uses about 5% of the energy of primary smelting — the single best energy arbitrage in materials.

Demand forecast to climb around 40% by 2030 on packaging, EVs and grid build-out. Scrap simply cannot keep pace; hundreds of billions of beverage cans are still landfilled each year.

The unglamorous high-ROI play: alloy-level sorting (LIBS/XRF), closed-loop automotive scrap contracts, and can-to-can systems. Physical assets, commodity-backed, 20-year lives.

Secondary sources supply roughly a third of total copper use. Battery recycling attracted enormous capital on the assumption that EV feedstock would arrive by 2025.

It didn't. The EV fleet is too young; most packs are still on the road. Announced li-ion recycling capacity vastly exceeds available black mass, and over 80% of it sits in China.

The IEA finds recycling could cut primary supply requirements for copper, lithium, nickel and cobalt by roughly a quarter to 40% by 2050 — but secondary supply only becomes material after 2030. Survive the valley, own the decade.

Roughly 9% of all plastic ever produced has been recycled. Waste reached 353 Mt in 2019 and is on track to nearly double by 2040. Recycled content in new plastic sits near 6% globally.

Voluntary targets have visibly broken. The Global Commitment's 2025 goals will be missed; reuse is stuck near 1–2% of packaging. Two rounds of UN treaty talks — Busan 2024, Geneva 2025 — closed without agreement.

Regulation replaces pledges. The EU packaging regulation applies from August 2026 with binding recycled-content minima to 2030. Europe becomes the de facto global plastics rulebook; compliant PET capacity gets a demand floor.

Global fibre production hit roughly 124 Mt in 2023, heading for ~160 Mt by 2030. Less than 1% of clothing is recycled fibre-to-fibre. The ~8% “recycled” share is almost entirely bottle-derived polyester — a downcycle, not a loop.

Circulose (Renewcell) filed for bankruptcy in early 2024 with a working plant and no long-term offtake. The clearest signal in the sector: supply arrived years before brand demand.

Separate textile collection became mandatory across the EU in 2025; ecodesign rules and Digital Product Passports land from 2027. Sorting infrastructure — not chemistry — is the binding constraint.

62 Mt generated in 2022, up 82% since 2010 — five times faster than documented recycling. Only 22.3% is formally collected and treated.

Around $91bn of recoverable metals sits inside the annual stream. On current trends volumes reach 82 Mt by 2030 while the collection rate falls toward 20%.

The EU right-to-repair directive must be in national law by July 2026, and repairability scores are spreading. Repair and refurbishment — not shredding — is where the value and the health case both sit.

The built environment consumes 30–40% of all materials. Sand and gravel — around 50 Gt a year — are the second most-extracted resource on the planet after water.

Headline recovery rates look high because demolition rubble is crushed into road base. Almost none of it re-enters structural concrete, and reusable steel sections are still routinely melted.

Largest tonnage, lowest technology risk, least capital. Material passports, design-for-disassembly, structural reuse markets and calcined-clay cements. This is where a 2030 target is actually won or lost.

1.05 billion tonnes of food wasted in 2022 — about 19% of everything reaching consumers, and 8–10% of global emissions. Households account for the majority.

Nutrient loops are barely closed at all: phosphorus is a finite, geopolitically concentrated resource that we mine, eat and flush.

Anaerobic digestion with contracted feedstock, nutrient recovery from wastewater, and organics collection in fast-urbanising cities. Modest returns, extraordinary system value.
