Pocket plastic scanners so small scrap dealers sell graded lots, not mixed
TL;DR Gradewell rents small scrap dealers a handheld near-infrared scanner that names the polymer in a second, plus a phone app that records each sorted lot. Dealers pay a monthly fee because graded plastic sells for more than mixed, and recyclers chasing recycled-content targets want lots they can trust.
Most plastic in Indian cities passes through a neighbourhood scrap dealer before it reaches a recycler. Those dealers sort by eye and touch, and anything they cannot name goes into the "mixed" pile. And the price gap is real - one Bengaluru doorstep rate list pays ₹12 a kilo for soft plastic and ₹10 for PET bottles, but ₹8 for mixed plastic and ₹5 for hard plastic[1].
Recyclers face the opposite problem. From 2025-26, brand owners must use 30% recycled content in rigid plastic packaging, rising to 60% from 2028-29[2]. They need clean single-polymer feed, and a bale with stray PVC or a wrong polymer costs them yield. So how does a small dealer prove what is in a lot? Right now, he can't afford to.
A dealer holds the Gradewell scanner against an item and the phone shows the polymer, such as PET, HDPE, PP, LDPE or PS, with a confidence score. Items the scanner cannot read, including black plastic, go to a separate bin rather than being guessed. Each finished bale gets a lot record with weight, polymer mix from spot checks, photos and date. Recyclers who buy through partner channels can see that record before paying.
The device uses off-the-shelf near-infrared modules, with a classification model tuned on Indian packaging. Public work shows this is possible but not finished - an open-source scanner from TU Delft reached about 70% accuracy in university tests and has paused development[3], and a CSIR lab in Chennai is building a similar handheld tool with an NMHS grant of ₹47,80,739[4]. Gradewell's job is to make it reliable enough for daily trade use.
The user is a scrap dealer or the operator of a dry-waste collection centre. They pay a monthly rental per scanner, priced well below the extra margin from one graded bale a week. Recyclers are the second payer, buying lot records or paying a premium for graded supply because they need recycled content they can document. Brand owners and EPR compliance firms may fund scanners for their supply chain.
The Plastic Waste Management (Amendment) Rules 2026, notified on 31 March 2026, keep rising recycled-content floors for every packaging category[2]. Handheld near-infrared hardware has become cheap enough for pilots, and machine-learning studies published in 2025 show handheld spectrometers can classify common plastics, with lower accuracy than bench-top units[5].
There is no public figure for handheld polymer scanners sold in India. The firmest signal is the price spread at the doorstep, where sorted soft plastic sells for 50% more than mixed[1]. The demand-side signal is regulatory, with recycled-content floors of 30–60% for rigid packaging[2]. Treat both as reasons to test and not as a market size.
A German sensor firm sells mobile near-infrared plastic identification to recyclers, without a public price[6]. One open-source scanner project is designed with input from informal recyclers in India and elsewhere, but is not sold[3]. CSIR's Polyscan is a research project with a recycling partner in Chikmagalur[4]. I found no Indian company renting scanners to small dealers with a lot record attached.
| Difficulty | Moderate (50/100) |
| Starting capital | ₹60 L–1.2 Cr |
| Time to launch | 9–12 months |
Accuracy on dirty, labelled, multilayer Indian packaging is the hardest part, and black plastic will not read at all. The device must survive dust and rough use and still cost little. Selling also takes field time, because dealers trust their own eyes and need proof that a buyer pays more for graded lots.
No licence covers the scanner itself, but recycling rules shape who you sell to.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't quote accuracy you haven't measured. Prototype scanners reached about 70% in tests[3], so publish your own yard results before any buyer relies on them.

Here's what can go south -
I like this for a founder with hardware and spectroscopy skills who will happily spend weeks in scrap yards. If you're hoping to sell a gadget without building recycler demand then skip it. First prove two things in one city - 95% accuracy on the five main polymers in real yard conditions, and a recycler that pays at least ₹2 a kilo more for scanned lots.
Plan for roughly ₹60 L–1.2 Cr for hardware development, model training and field pilots.
It can be if recyclers pay more for graded lots. Sorted soft plastic already sells for about 50% more than mixed at the doorstep in Bengaluru, but you need to prove the premium holds.
Yes, informal and small-scale recycling exists in many countries. Check local radio approval rules for the device first.

Thinking about building Gradewell or something close to it? The make-or-break work is hitting yard-grade accuracy and getting one recycler to pay more for scanned lots, and I can help you test both. If you need a hand, you know where to find me. Talk to Yash →
