What are materials recovery and remediation activities in ISIC Rev. 5?

Materials recovery and remediation in ISIC Rev. 5, published by the UN Statistics Division, cover two linked but different kinds of work. Materials recovery sorts, processes and prepares waste material so it can be used again, while remediation cleans up contaminated soil, water and sites. Both sit in Section E because they deal with material and land after use, but recovery looks forward to reuse and remediation looks backward to repair. Neither activity is a licence, a recycling claim or a code assignment for any particular reader.

Why pair recovery and remediation in one guide if they point in opposite directions?

The pairing is useful precisely because the directions differ. Recovery takes material that has been discarded and prepares it for a second life. Remediation takes land or water that has been damaged and works to restore it. One moves material forward into production again; the other moves a site backward toward a cleaner state. What links them is timing: both happen after use, after production, after disposal, after contamination. Section E gathers that after use work together, so that statisticians can see how much effort goes into reuse and repair as distinct from how much waste is simply collected or disposed of.

Which jobs belong on the recovery side, and which on the remediation side?

The following kinds of work are described in ISIC Rev. 5, published by the UN Statistics Division, as part of this grouping:

• Sorting and processing of recyclable materials
• Dismantling of waste items for material recovery
• Preparation of secondary raw materials
• Cleanup of contaminated soil and groundwater
• Remediation of former industrial sites

The first three items trace the recovery chain: sort it, take it apart, prepare it. The last two trace remediation: clean the soil and water, restore the site. That list is an orientation aid, not a substitute for the full class description. An apparent heading fit without a detail fit, in materials recovery and remediation, is settled by the Rev. 5 publication detail, and a formal record still needs the national institute.

What do the two worked cases show, step by step?

Take the paper recovery plant first. Loads arrive mixed. Workers and machines shred, sort and bale recovered paper, separating grades that mills can use. At the end of that chain the output is not a new notebook or a new box. It is prepared secondary material, ready for a manufacturer to turn into something new. That stopping point is the heart of the recovery description: preparation, not final manufacture.

Now take the former factory site. A team removes contaminated soil, treats groundwater, and works through the site in stages until the contamination described in the Rev. 5 description has been addressed. The team does not build a new factory on the site as part of that cleanup work, and it does not manufacture a product from the soil it removes. Its output is a cleaner site. Put the two cases side by side and the contrast sharpens: one prepares material for reuse, the other repairs a place. Both sit in Section E, but they are not interchangeable, and a firm doing both is doing two kinds of work.

Where do recovery and remediation stop?

Simply collecting waste without processing it for recovery is waste collection, not recovery. The collection crew moves material; the recovery plant changes its state so it can be used again. At the other end, manufacturing a new product from recovered material is manufacturing, not recovery. The recovery plant prepares the input; the factory turns that input into a finished product. Recovery sits between those poles, and losing either boundary would blur the statistics: collection numbers would swallow preparation work, or manufacturing numbers would swallow preparation work, and the reuse chain itself would disappear from view.

A similar care applies to remediation. Digging a trench for a new building on a clean site is construction, not remediation. Cleaning a contaminated site is remediation because the work responds to contamination. The trigger is the condition of the soil, water or site, not the tools used, since excavators appear in both jobs.

What should you read next if your case sits near a boundary?

Where materials recovery and remediation meets a boundary, national practice may shade the answer, above all where a country has a large local industry or organises the service distinctively. The international description remains the shared reference, but the national version and the statistical office guidance show how that reference is applied locally, and both should be consulted for a formal record. If the activity in mind sits near a boundary described here, reading both neighbouring descriptions before choosing the better statistical fit is the sensible step, and the explanatory notes in the Rev. 5 publication give detail that a short guide cannot cover.

The UN Statistics Division classification detail and the ISIC Rev. 5 publication in the frontmatter support every code statement about materials recovery and remediation in this guide.

Use this guide only as general background on a statistical classification. It cannot assign you a code, decide your principal activity, or register your business, and the only confirmation that settles those questions comes from the national statistical institute or business register that holds your record.
