The acquisition we told them not to make

Eight weeks to find out whether there was anything worth buying

Most of the world's paper starts as wood. A smaller share starts as something that grew last season and would otherwise be burned: wheat and rice straw, sugarcane bagasse, bamboo, reed. Pulping those is a different business from pulping wood. The fibre is shorter, the silica content is punishing, and the equipment that handles it is not the equipment that handles a log.

Eight weeks, four phases. Two weeks to size the market, two and a half to map the customers and what they need, two and a half to find and evaluate the equipment makers, one to put it in front of the leadership team. The deadline did not move.

Our client builds that equipment. It is a global pulp and paper machinery group with a complete portfolio for wood fibre and an incomplete one for everything else. Its customers in Asia were pulping straw and bagasse and bamboo, buying the parts of the line the client could supply and buying the rest from someone else.

The proposition on the table was to buy that someone else. Acquire a regional equipment maker with agro-pulping references, inherit the technology and the customer relationships, and close the gap in one move. A long list of candidates already existed internally.

The question the client asked was which of them to buy. The question underneath it, which nobody had answered, was whether the market was worth buying into at all.

There is a great deal of data, and none of it is the number

Agricultural residue is one of the best measured commodities on earth. You can find, for any large producing country, how many million tonnes of straw and bagasse and empty fruit bunches it generates each year. That data is abundant, free and completely useless for this question.

Feedstock availability is not production, production is not capacity, and capacity is not equipment spend. Three gaps, and every one of them has to be crossed deliberately.

What it does not tell you is how much of that residue is pulped, how much pulping capacity exists, how old that capacity is, or what anyone spends on the machinery. There is no published market for agro-pulping equipment, because it is not a category anybody reports.

There is a second problem that is specific to this industry. Roughly three quarters of the mills involved run blended systems: some agricultural fibre, some wood, some recovered paper, in proportions that change with the price of each. There is almost no such thing as a pure agro-pulp mill, so there is almost no such thing as a clean agro-pulp number. Everything has to be apportioned, and the apportionment has to be stated.

Size it at the equipment, or you are sizing something else

There is no published figure for what the world spends on agro-pulping machinery, so it had to be built. The formula was fixed before any data went into it, and applied identically in every country.

A market size that cannot be taken apart is not evidence. It is an assertion with a currency symbol in front of it.

Every one of those four terms is arguable, and that is the point: they are visible, so they can be argued with. A number handed over as a single figure cannot be. When the client's leadership challenged the outcome, the conversation was about the equipment share and the replacement interval, which is a productive argument, rather than about whether the number was real.

The answer was €57 million a year across the region in 2024, growing to about €63 million by 2030. That is a compound rate of roughly 2.6 per cent, and in absolute terms it is under €7 million of additional annual spend spread over six years and three countries.

For a machinery group of this size, that is not a market you buy a company to enter. It is the single most consequential finding in the study and it arrived in week two.

The value is flat because the volume is falling

A flat equipment market usually means a stable industry. Here it means something less comfortable. The value holds up while the underlying production shrinks, because one feedstock is growing fast enough to offset the collapse of the others.

What this does to an acquisition case. A supplier whose references are in straw has references in a segment losing ten per cent a year. The reference base has to be read by feedstock, not by count, and that is not how supplier long lists are usually assembled.

China's non-wood pulp production fell from 6.8 million tonnes in 2015 to just over 5 million in 2024. Straw lost two thirds of its volume. Reed lost four fifths. Bagasse declined steadily. Bamboo grew by 7 per cent a year and now accounts for more than half of what remains.

The reason is the same in each case, and it is economics rather than policy. Agricultural fibre carries silica, silica has to be removed, removal costs money, and when wood is cheap the mills convert to wood. Several of them did exactly that. The mills that stayed are the ones where the feedstock advantage survives the silica penalty, and for now that mostly means bamboo.

One country, one province, a handful of mills

Concentration compounds the size problem. China is about three quarters of the regional equipment opportunity, €41.8 million of the €56.8 million total in 2024. Inside China the growth is bamboo, and bamboo is not spread across the country.

Thirty-three mills in total, in three provinces, and within the growing segment the top four mills control around 60 per cent of capacity. The addressable customer set for an acquired supplier is not a market. It is a list you could fit on one page, and the client already sells to some of them.

That cuts both ways. It makes an acquisition harder to justify, because the customer relationships being bought are few and already partly held. It also makes the alternative easier, because a customer set that small can be approached directly.

India is a bolt-on, and the reason is not price

India is the second market and it is small: €9.3 million a year, essentially flat since 2020, growing to about €10.6 million by 2030. Bagasse leads, wheat straw follows, bamboo is negligible. Capacity utilisation runs in the high seventies to high eighties, so there is no idle capacity waiting to be modernised.

The preference for local suppliers is structural, not budgetary. It survives the client winning individual components on merit.

Three mill projects were tracked in detail, adding around 350 thousand tonnes of capacity to bagasse and straw between 2027 and 2028. What they are buying is instructive. One is buying a screen room and sourcing the rest locally. One is buying a single washing line. One is buying cooking technology and a screen room. In every case the majority of the line goes to a local supplier or comes second hand.

This is the finding that turns India from a target market into a relationship question. A supplier there brings customer access the client does not have. It does not bring a market large enough to justify buying the company for its revenue. If a deal happens in India it is for the door, not for the room behind it.

A hundred and fifty million tonnes of feedstock and no market at all

Indonesia was in scope because on paper it looks like the obvious opportunity. It generates roughly 150 million tonnes of agricultural residue a year: empty fruit bunches from palm oil, rice straw, bagasse. Empty fruit bunches alone have grown at 7 per cent a year for a decade.

Why this belongs in the report rather than in a footnote. Indonesia is the clearest available demonstration that feedstock availability tells you nothing about equipment demand. Anyone sizing this market from residue statistics would have put Indonesia at the top of the list. It belongs at the bottom, and the study says so with the reason attached.

It has no commercial agro-pulp production. None. Four mills tried and all four have closed or converted to something else.

The reason is that Indonesia is one of the cheapest places on earth to grow plantation wood, and the same integrated groups own the plantations and the mills. Agricultural fibre has to beat wood on delivered cost inside a business that already owns the wood, and it does not. Around 62 per cent of the empty fruit bunches and 70 per cent of the bagasse are burned for energy instead, which is a real market, just not this one.

Twelve suppliers scored, and three gaps that actually matter

The supplier work ran in parallel with the market work, on the assumption that it might turn out to be unnecessary. It was still worth doing, because it answered a different question: what exactly is missing.

The step that removed the most candidates was not the scorecard. It was putting each supplier's claimed agro-pulp experience to industry specialists and asking whether the reference projects were real. Ten of twenty-one did not survive that. A capability claim on a website is not a reference, and in a small industry the people who run the mills know which is which.

Three suppliers separated clearly from the rest, two of them in China and one in India. Below them the scores fall away quickly, and the bottom four have effectively no credible agro-pulp presence at all.

The more useful output was the technology map. The agro-pulping line was broken into seven stages and thirty-six pieces of equipment, and the client's own portfolio marked honestly against each one.

The client could already supply twenty of the thirty-six. Bleaching and drying was complete. Recovery and waste management was almost complete. The gaps were not spread evenly across the line: they cluster in three places, and all three are specifically about handling fibre that is not wood.

1. Pre-treatment, where nothing was covered at all

   Stone catching, depithing, pith pressing, wash water classification. Five pieces of equipment, five gaps. This is the stage that exists because the feedstock arrives with soil, sand and pith in it.

2. Continuous cooking for non-wood fibre

   The client sells batch digesters and one chemistry. The continuous digester used for straw and bagasse, and the alternative chemistry that goes with it, were both missing.

3. Silica and ash handling

   One piece of equipment out of thirty-six, and the one the mills raised most often. Silica is the reason this fibre is difficult and the reason mills convert away from it.

What the numbers rest on

Every market figure on this page can be rebuilt from the formula in the first finding and the volumes in the second. Where a figure is an assumption rather than a measurement, it is labelled as one on the exhibit where it appears.

On anonymity. The client is not named. Neither is any of the twenty-one suppliers screened, the three evaluated in depth, the mills interviewed, nor the provinces where the production concentrates. Three suppliers were assessed as acquisition candidates and one of them was assessed as an entry route: naming any of them would disclose both the client's intentions and theirs. The method and every figure are reproduced in full.
