What is trash deduction in cane, and how is it measured?

Trash deduction is a cut from the cane weight paid for, made to reflect leaves, tops, roots and other matter that carries no recoverable sugar. Measurement and legality vary by state: Maharashtra allows a flat 4.5% on harvester-cut cane under a 2022 government resolution, while Uttar Pradesh rules bar a weight cut for poorly stripped cane.

What counts as trash

Trash is the matter delivered with the stalk that the mill cannot turn into sugar. It usually means dry and green leaves, tops, roots and soil. Maharashtra's purchase tax law, for example, allows for the top of the plant, leaves and other trash usually present.

Researchers use the wider term extraneous matter. Mills also care about it because it reduces juice quality. It also adds to the weight on which the mill pays.

What the central Order says

The word trash does not appear in the Sugarcane (Control) Order, 1966 copies we read. Clause 3A lists the rebates that may be allowed from the price:

Burnt, stale or dried cane, and rejected varieties, capped at the estimated shortfall in recovery.
Binding material where cane comes in bundles, capped at 1,000 grams per quintal, which is 1%.
Cane supplied ex-field, capped at the estimated cost of harvesting.
Transport from a purchasing centre, at a rate fixed by the Central Government.

Where states differ

The 1% binding allowance is sometimes confused with a trash allowance. They are separate ideas. State rules vary, so read your own.

State	Position we could verify
Maharashtra	A Cooperation Department resolution of 12 October 2022 allows a flat 4.5% deduction from the weight of harvester-cut cane. A March 2025 Commissionerate letter said this covers farmers' cane and does not apply to harvester owners' bills. A circular of 4 April 2025 told factories not to deduct trash from those bills.
Uttar Pradesh	Rule 42 of the 1954 Rules bars a weight cut for improperly stripped cane and allows other weight deductions only where a central order permits. Rule 47 limits deductions from the amount due, with exceptions for society dues.
Karnataka	Section 8(4) of the 2013 Act limits deductions on net weight for binding material to what the Centre allows. We found no separate trash clause.
Tamil Nadu	Payment is on recorded weight at the factory under section 15(2) of the 2018 Act. We found no trash clause in the Act.

How trash is measured

There are two broad approaches.

Flat rate. A fixed percentage applies to every load of a type. It is simple and quick, and it ignores how clean the load really is. Maharashtra's harvester rule works this way.

Sampling. Staff take a sample from a load, separate stalk from trash and tops, and weigh each part. Trash % = weight of extraneous matter / weight of sample x 100. It reflects the load, but the sample must be fair and the work takes time. We found no national Indian standard for this method, so agree one locally and get it approved where your state requires.

What the research shows

Published Indian data is thin. One short study sampled three Haryana mills in April 2019. Machine-cut cane had 1.7% trash and 5.7% green top. Hand-cut cane had 1.0% and 2.9%. Recovery of the mixed machine-cut produce was 0.33 unit below its clean cane and 0.71 unit below hand-cut cane.

These are small samples from one region and one month. They do not support any particular deduction rate. Machine owners have sought 1.5%, and a 2022 opinion column reported a study group recommending 1.5% to 2%. We could not see that report.

What a percentage costs

The rate decides real money. This table takes a 25-tonne load at the 2026-27 base FRP of Rs 3,650 per tonne.

Deduction	Weight cut (tonnes)	Value (Rs)
1.0%	0.250	912.50
1.5%	0.375	1,368.75
4.5%	1.125	4,106.25
5.0%	1.250	4,562.50

Control checklist

This is general information. Read the original resolution or circular, since we relied on press reports of the Maharashtra documents. In SugarOS, weights are captured from the weighbridge and cannot be typed, so any deduction starts from a recorded net weight.

Note the legal basis for any deduction on file, with its date.
Show gross, tare, net and the deduction as separate lines on the slip and bill.
Apply the rule by harvest type and keep that field on the weighment.
Keep sample records with date, load, staff name and weights.
Let grower representatives see the method.
Do not apply the same deduction to grower and contractor without checking the state rule.
Review the rate with your accountant and legal adviser each season.

Frequently asked questions

Is 4.5% trash deduction legal in every state?

No. The 4.5% figure comes from a Maharashtra resolution for harvester-cut cane. Other states have their own rules, and Uttar Pradesh rules restrict weight deductions.

Does trash deduction apply to hand-cut cane in Maharashtra?

The resolution as reported covers harvester-cut cane. Check the text and your state's latest circular before applying anything to hand-cut cane.

Can a mill reject a dirty load?

We did not find a rule on this that applies across India. Check your state rules, your supply agreement and any cane commissioner direction.

Does trash affect the recovery used for FRP?

It can, since recovery is measured on cane crushed and trash lowers sugar made per tonne. The Haryana study showed a lower recovery for mixed machine-cut produce, though from a small sample.
