The whole chain
A tonne of scrap goes through five roles before it becomes steel again: whoever generates it, whoever grades and buys it, whoever moves it, whoever weighs it and whoever melts it. Bluegreen buys from the generator, coordinates the rest and sells to the mill, with tax and transport documents at every step. See how each step is regulated.
- 01
Generator
The company where the scrap is created: a plant, a construction site, a workshop, a yard. It sells its material and is paid with a CFDI invoice.
- 02
Grading
We classify the material by type and quality, estimate the weight and make a written offer.
- 03
Pickup and transport
A carrier with a federal permit collects it with a Carta Porte. The outgoing weight is recorded on a scale.
- 04
Weighing and delivery
The mill weighs and inspects it at its plant. Every weight is kept with its ticket and photo.
- 05
Melting
The electric arc furnace melts the scrap into new steel: rebar, sections, wire rod or sheet.
Scrap generators
We buy from companies with a tax ID (RFC) that generate steel scrap in their operations. Each industry produces different materials with different values. These are the ones we serve, from the most common to the most specialised.
- Sells
Automotive and auto parts
Stamping offcuts, clean low residual sheet clippings (the "busheling" type), rejected parts and retired tooling. Usually the highest value scrap because it is so clean.
- Sells
Metalworking and machining
Steel turnings and chips, bar and plate offcuts, out of spec parts. Turnings with cutting oil are accepted drained; with excess oil their handling changes.
- Sells
Structures and fabrication
Offcuts of sections, beams, angles, heavy plate and tube. Dense material that is easy to load and goes in as heavy scrap.
- Sells
Construction and demolition
Rebar, beams, dismantled structures, mesh and steel formwork. It often comes mixed with concrete or wood; it is separated or the price is adjusted for impurities.
- Sells
Dismantling and plant closures
Retired machinery, industrial buildings, clean tanks and piping. We coordinate on site cutting and removal in stages.
- Sells
Appliances
Sheet offcuts, casings and rejected parts from the line. The steel comes out clean; refrigerant and electrical components are removed first.
- Sells
Maquiladoras and IMMEX companies
Production scrap from temporarily imported goods. It has its own customs rules, so its destination is documented before it is sold.
- Sells
Railways
Rail, wheels, axles, steel sleepers and retired rolling stock. Only with documents proving ownership: rail is among the most stolen materials in the country.
- Sells
Oil, gas and energy
Pipe, structures, towers, tanks and plant equipment. Anything that held hydrocarbons is cleaned and certified before it moves.
- Sells
Mining
Machinery, structures, worn grinding balls and wear plates. Large pieces that need cutting and rigging.
- Sells
Ports, shipyards and shipping
Ship plate, retired containers, chain and dock structures.
- Sells
Fleets and transport
Retired chassis, trailers and dry vans, wheels and suspension parts. Bought with an invoice or vehicle deregistration.
- Sells
Agribusiness
Farm machinery and implements, silos and storage structures.
- Sells
Telecoms and power
Towers, hardware and structures. Transformers are not accepted without proof they contain no oils with polychlorinated biphenyls.
- Sells
Foundries and forges
Returns, risers, failed castings and rejected iron and steel parts.
- Sells
Metal packaging
Empty, clean steel drums and containers. If they held hazardous substances, they are decontaminated first.
- Sells
Public sector
Government agencies and state companies sell their scrap through tenders or auctions. We take part under the requirements of each call.
- Sells
Collection centres and yards
Formal collectors that gather scrap from many sources and sell it by volume. We ask for their environmental registration and the traceability of what they buy.
Tax ID (RFC) and tax status certificate, an on site contact, access for pickup and, for sensitive materials (rail, cable, manhole covers, utility equipment), documents proving ownership.
Steel mills and foundries
On the other side are those who melt the scrap. In Mexico most steel is made in electric arc furnaces, which use scrap as their main raw material. See how each production route works.
- Buys
Electric arc furnace long products mills
They make rebar, wire rod, sections and bars. The natural destination for heavy melting scrap and structural cuts.
- Buys
Flat products mills
They make sheet and plate. They ask for clean scrap low in copper and tin, such as stamping offcuts, because residuals affect thin sheet.
- Buys
Iron and steel foundries
They make castings for industry. They buy scrap selected by chemistry, sometimes with a chemical analysis of each load.
- Buys
Stainless and alloy plants
They buy stainless separated by series (304, 316, 430) to recover the nickel, chromium and molybdenum it already contains.
We deliver each mill material graded to the specification it asks for, with origin weight, Carta Porte, CFDI and the traceability of the lot. When it is weighed at the plant, the destination weight closes the sale.
Logistics and services
Moving scrap means moving heavy freight on federal highways. We work with providers that meet what the law asks of each one.
- Service
Freight carriers
With a federal freight permit, vehicles within weight and dimension limits, and the ability to issue the Carta Porte supplement.
- Service
Scales
Truck scales verified under the weighing instrument standard. Every weighing leaves a ticket with folio, date, time and weight.
- Service
Rigging
Cranes, electromagnets, forklifts and loaders to load on site without damaging facilities.
- Service
Cutting and preparation
Torch cutting and shears to bring pieces to the size the mill asks for, and baling for light material.
- Service
Material analysis
Laboratories and spectrometry equipment to identify alloys, especially stainless.
- Service
Tax and environmental advice
Accountants and consultants who support the generator with its CFDI, withholdings, management plan or sustainability reports.
From one tonne to contracts
| Volume | How we work | Documents |
|---|---|---|
| A single lot | Offer per lot, scheduled pickup, payment on settlement | CFDI, Carta Porte, scale ticket, impact certificate |
| Recurring generation | Pickup calendar and an agreed reference price | The above, plus a periodic consolidated report |
| Corporate contract | Master agreement, on site containers where it applies, several plants | The above, plus per plant reports for sustainability |
What we do not accept
- Material without documents proving its legal origin, or offered by someone without a tax ID.
- Goods that often come from theft: cable, manhole covers, road signs, rail or utility equipment without the owner's paperwork.
- Closed containers, tanks or pipe with fuel, gas or chemical residues without a cleaning certificate.
- Hazardous waste and any material suspected of containing radioactive sources.
- Scrap contaminated with polychlorinated biphenyl oils, asbestos or lead paint without special handling.
These rules protect the generator, the mill and us. Our terms and conditions set them out in detail.
Frequently asked questions
Do you buy scrap from individuals?
We buy from companies and from individuals with business activity who have a tax ID and can invoice. The invoice is what lets us trace the origin of the material and meet tax withholding rules.
What is the minimum volume?
We handle lots from around one tonne. For small volumes we group pickups by area so the freight makes sense.
Do you work across Mexico?
We serve generators in different states depending on our carriers' routes and where the mills are. Ask for an offer and we will tell you whether we reach your plant.
Can I sell if I am an IMMEX company?
Yes. Scrap from temporarily imported goods has its own customs rules, so its destination is documented first. We ask for that support before pickup.
How do I become a carrier or provider?
Write to us with your federal freight permit, your vehicles and your area. We register you in the partner portal once your paperwork is complete.
