Singapore Scrap Metal Industry: History & Facts

From Tin Shacks to Industrial Yards: 1960s Origins

Scrap metal recovery in Singapore is older than the republic itself. Informal karung guni (rag-and-bone) traders collected copper, brass and steel from colonial-era buildings, shipyards and godowns from the 1950s onward. What changed everything was Singapore’s industrialisation push after 1965.

The Economic Development Board’s Jurong Industrial Estate, launched in 1968, created an instant, continuous source of process scrap — offcuts from shipbuilding, structural steel waste from construction, copper wire from electrical works. Within a decade, clusters of scrapyards had formed around Gul Circle, Tuas, and later Sungei Kadut.

The Shipbuilding Era — Scrap as Feedstock

The 1970s and 80s were the golden years for Singapore heavy industry. The Keppel, Sembawang and Jurong shipyards were building and repairing a steady flow of tankers, rig platforms and cargo vessels. Shipbreaking — the dismantling of end-of-life vessels — generated enormous tonnages of ferrous and non-ferrous scrap, much of which was processed locally before being re-sold to mills in Japan, Korea and, later, China.

This shipyard feedstock is the reason Singapore developed early expertise in separating ferrous vs non-ferrous metals at scale — copper cabling, brass fittings, stainless piping and structural steel all need different processing routes.

Becoming a Regional Trading Hub

By the 1990s, Singapore had leveraged three advantages — PSA’s world-class port, a transparent rule of law, and a free-port customs regime — into a position as Southeast Asia’s scrap metal trading hub, not just a processing one. Scrap arrived from Indonesia, Malaysia, Myanmar and Cambodia, got sorted, graded and documented in Singapore, and was re-exported to mills across Asia.

This trading function is still central. Singapore today is home to LME-approved warehousing for copper and aluminium, which means physical metal can be delivered against London Metal Exchange contracts from Singapore warehouses. For background on how LME pricing flows into local scrap rates, see our piece on the LME and Singapore scrap.

Scale of the Industry Today

• Singapore generates an estimated 1.2-1.5 million tonnes of metal waste annually (ferrous + non-ferrous combined, based on NEA waste statistics).
• Metal has one of the highest recycling rates of any material stream in Singapore — consistently above 90% in recent years, per NEA figures.
• The industry supports dozens of licensed scrapyards and traders, concentrated in Tuas, Gul Circle, Sungei Kadut and parts of Kranji.
• Singapore re-exports scrap to steel mills in Malaysia, Thailand, Vietnam, India and — historically — China, though Chinese import restrictions from 2019 shifted flows toward Southeast Asian mills.

Key Nodes — Where Singapore’s Scrap Moves

• Jurong / Tuas: The heavy-industrial spine. Shipyards, steel fabricators, and the largest scrapyards cluster here — including Molten Steel’s operations.
• Gul Circle: Historically the chemicals + metals zone. Several long-running scrap merchants are based on Gul Road.
• Sungei Kadut: A northern industrial estate that hosts sawmills, timber yards, and a cluster of small-to-medium scrap operators.
• PSA Port: The export gateway. Containerised scrap and bulk scrap vessels depart for regional mills.

Molten Steel — Founded 2006

Molten Steel Pte Ltd was founded in 2006 and has operated continuously as a licensed scrap metal buyer and processor in Singapore. Our focus is industrial and commercial scrap — ferrous and non-ferrous — bought at LME-benchmarked rates. Pricing is transparent against published benchmarks, which you can verify any time on our LME-to-local pricing explainer.

The team carries cumulative decades of experience across metal trading, logistics and yard operations — a direct line back to the industry’s post-1965 industrial roots.

What’s Next for the Industry

Three shifts are reshaping Singapore scrap in the mid-2020s: the EV transition (different copper/aluminium demand patterns, new battery-material recovery streams), tighter Basel Convention export rules on mixed scrap, and rising focus on carbon accounting as buyers and downstream mills quantify Scope 3 emissions. The core economics — turn waste metal into feedstock for new metal — are unchanged, but the documentation and traceability requirements keep rising.

The Regulatory Evolution

Singapore’s scrap metal regulatory regime has tightened in step with the industry’s scale. Key milestones:

• 1983 — Secondhand Goods Dealers Act. Established the police-licensing framework scrap dealers still operate under today.
• 2000s — NEA oversight on environmental handling. Yards must manage oil, coolants and hazardous residues to NEA standards.
• 2014 — Resource Sustainability initiatives. Singapore began formally tracking recycling rates by material, putting metal at the top of the league table.
• 2019 onward — Basel Convention alignment. Tighter documentation for cross-border movement of certain scrap categories.

Who Buys Singapore Scrap Today

The buyer base has shifted meaningfully over the decades. In the 1980s and 90s, Japan and Korea were dominant. Through the 2000s and early 2010s, China pulled in enormous volumes. Post-2019 Chinese import restrictions, the regional Southeast Asian mills — particularly in Malaysia, Vietnam and Thailand — became the anchor destinations for Singapore scrap, supplemented by India and occasional long-haul shipments to Taiwan or the Middle East. Our LME pricing explainer walks through how these buyer dynamics flow into what local sellers get paid.

Employment, Skills and the Yard Workforce

The Singapore scrap industry employs thousands across yard operations, logistics, trading and administration. The skill set has evolved well beyond sorting and cutting — a modern yard needs staff who can identify complex alloys, operate hydraulic shears and balers safely, document shipments to international standards, read LME and Platts benchmarks, and manage hazardous residues to NEA rules. Veteran yard supervisors often carry 20-30 years of on-the-job experience, and that institutional memory is a real competitive advantage. Newer entrants are trained on metal identification, grading conventions, and safety protocols before they handle material independently.

What the History Tells Us

Singapore’s scrap industry grew because the country industrialised quickly, built world-class port infrastructure, and kept its legal and regulatory environment consistent. None of those advantages are going away. The industry will change — more EV-driven demand, tighter documentation, more automation — but Singapore’s core role as a trusted regional processing and trading node is durable.
