Pioneering sustainability in semiconductor salvage.

We turn semiconductor scrap into material for future technologies. Factories call us when machines need to go. We move them out, resell what still works, and dismantle and sort the rest so the metal goes back into production instead of to landfill.

E-waste and collection programmes

We take regulated e-waste: ICT equipment, appliances, phones, batteries, lamps and solar panels. For business customers we collect on a schedule and give you the figures for ESG reporting.

How we work

You call a tender. We handle the rest.

When a factory puts machines out to tender, we look at each one and decide whether it is worth more resold or scrapped. Either way, our people and our trucks move it out.

Your factory calls a tender for its machines
For resale

Machines that still have a life

  1. We submit an offer for the machines.
  2. Our team moves them out of your factory with our own manpower and logistics.
  3. We store them for sale, or take them apart and sell the electronic parts.
For scrap

Machines that need to be destroyed

  1. We submit an offer for the scrap.
  2. Our team moves them out of your factory with our own manpower and logistics.
  3. They go through our scrap process, below, and you get a Certificate of Destruction.

Scrap process

From your factory floor to sorted metal.

STEP 01

Disposal request

Your factory tells us which machines need to be disposed of.

STEP 02

Risk assessment

We send you a risk assessment for the removal before any work starts on site.

STEP 03

Move-out

Our people and our trucks take the machines out and bring them to the yard.

STEP 04

Dismantling

Workers start taking the machines apart as soon as they arrive at the yard.

STEP 05

Evidence

We take photos and video of the destruction so you have proof it was done.

STEP 06

Segregation

Metals are separated by type: iron, stainless steel, aluminium, wire and so on.

STEP 07

Binned for collection

Metals go into their own skid bins. E-waste goes into jumbo bags. Both wait for payment and collection by buyers.

STEP 08

Certificate

You get a Certificate of Destruction for the scrapped machines.

Certificate of Destruction

Proof your equipment was destroyed.

Each certificate is issued on our letterhead. It gives the collection date, lists the items destroyed, and is signed and stamped by us. Photos of the destruction are attached, so your auditors can see it happened.

  • Dated, itemised, signed and company-stamped.
  • Photo evidence of the destruction attached.
  • Photos and video taken throughout the destruction.

About us

From a small workshop to the semiconductor industry's scrapyard.

Our founder, Mr Ang Siew Hor, started Sim Hock Huat in a small workshop in Ang Mo Kio Industrial Park. He collected bins of scrap metal from CNC factories.

Then the CNC factories in Singapore started closing and moving overseas. Mr Ang noticed they had been supplying parts to semiconductor and other manufacturers further down the chain, so he went to those factories for scrap instead.

That is still what we do: reduce electronic waste by putting today's semiconductor scrap back into the production cycle as tomorrow's raw material.

At the gate

We check every load before it gets tipped.

Once a load is tipped and mixed in with everything else, anything wrong in it is much harder to find and much more expensive to deal with. So every delivery goes through the same four steps first.

STEP 01

Pre-booked

Suppliers book the delivery in advance against a purchase contract. We tell them upfront what we will and will not take.

STEP 02

Weighbridge

The truck goes to the weighbridge first. We check the load against the booking and record the weight, the time, the material and who brought it.

STEP 03

Visual inspection

We look over the load before anyone tips it: contamination, anything on the banned list, signs of hazardous substances. It all goes on a checklist.

STEP 04

Verification

We spread the load out and scan it with a handheld XRF to confirm the grade. If a reading looks off, or you disagree with our grading, it goes for benchtop or lab analysis.

Accepted

We take the load when

  • It matches our scrap spec on sight.
  • The XRF reading confirms the grade.
  • We find nothing banned or hazardous in it.
  • The paperwork matches what turned up.
  • The weighbridge record is complete and right.
Rejected

We turn it away when

  • We find hazardous material, or something on the banned list.
  • The grade is badly wrong and we cannot sort it out with you.
  • The paperwork is missing, faked, or does not match the load.
  • We pick up radioactive material. That load is quarantined on the spot.
  • The supplier skipped the pre-acceptance steps.

What we look for before tipping

Sealed containers and gas cylinders, batteries, anything with a radiation warning on it, oil-stained metal, powders we cannot identify, and more PVC-coated cable than the description accounts for. With e-waste we also check that battery terminals are taped and nothing is swollen or leaking, that the lamps are not broken, and that the refrigerant circuit in an appliance is still sealed. Every e-waste load gets a radiation screen.

Responsibility

What we owe the people and places around us.

Environmental

We get back as much metal as we can, so less goes to landfill and less new metal has to be mined.

Ethical

We are straight about our licences and our paperwork, and fair to our customers, suppliers and staff.

Economic

We pay for what is actually in the load, and we put scrap back into production as raw material.

Environment

What we are aiming for this year.

These are our environmental targets for FY2026/27. Each one comes from a significant environmental aspect we identified at the yard. We track them and go through them at management review.

Our environmental policy

  • Prevent pollution and look after the environment at Tuas South and around us.
  • Follow Singapore environmental law, including the EPMA, the Environmental Public Health Act and the Resource Sustainability Act.
  • Hold every NEA licence we need to collect, transport and process scrap metal, and to handle e-waste.
  • Get back as much ferrous and non-ferrous metal as we can, so less goes to landfill and less new metal has to be mined.
  • Use less energy, and put out less waste and fewer emissions when we process material.
  • Get customers to separate material before it reaches us, because it recycles better that way.
  • Be straight about our licences and our paperwork.

Climate

Climate change matters to how we run the business. We are lining up with the Singapore Green Plan 2030 and the national Net Zero 2050 target.

Between 2025 and 2027 we are working out our Scope 1 and Scope 2 emissions baseline, auditing what our main processes use, and tracking fuel and electricity. We are doing the easy things first: LED lighting, less idling, better routing for the lorries. From 2028 we set reduction targets against that baseline, move to renewable electricity, and swap out diesel equipment where we can.

Compliance

Our licences and our records.

This is what procurement and EHS teams usually ask us for.

NEA licences

We hold a General Waste Collector (GWC) licence and a General Waste Disposal Facility (GWDF) licence. These cover collecting and handling waste from other companies.

National Environment Agency

Toxic industrial waste

Toxic industrial waste does not go in a general waste skip and does not go near a stormwater drain. We keep it covered, on a sealed floor, inside bunding big enough to hold 110% of the largest container. Only NEA-licensed TIW collectors take it away, and we check their licence is still valid before we use them.

Environmental Public Health Act

Regulated e-waste

We keep batteries, lamps and ICT equipment apart from each other in a covered, locked area. E-waste and hazardous parts go only to licensed e-waste recyclers or licensed waste collectors, and we keep the receipt.

Resource Sustainability Act 2019

Records

We record the weight, type and source of every e-waste load that comes in, the weight and destination of what goes back out, our collectors' licences, and the radiation screening results. We keep all of it for five years. Where we have to report as a licensee, the figures go to NEA in the first quarter for the year before.

Five-year retention

Emergency preparedness

We have an emergency response plan for fires, including lithium battery fires, for chemical releases and for radiation incidents. We review it at least once a year and work it through with SCDF, NEA, MOM and SPF.

Fire Safety Act

ISO 14001:2015

Our EMS manual, aspects procedure and operational control procedures are written to the standard. They cover our scope, our policy, the environmental aspects of the yard, our legal obligations, our objectives, the day-to-day controls and what we do in an emergency. We are working towards certification and will put the certificate number and the certification body here once we have it.

Working towards certification

Certificate of Destruction

Every scrapped machine is covered by a signed and stamped Certificate of Destruction with photo evidence. That gives you an audit trail showing the equipment did not go back on the market.
