MushComb's Answers to Mushroom Farming's Biggest Cost Problem

Harvesting can account for half of a farm's total production costs. Here is what the industry's most experienced growers are doing about it. This article is published in partnership with MushComb.
A Booming Market With a Labour Problem
The global mushroom market is large, growing, and structurally under-equipped. Valued at around $65 billion in 2024, it is projected to exceed $100 billion by 2030, driven by rising demand for plant-based protein, functional nutrition, and a broadening culinary palette that has elevated oyster and shiitake mushrooms from Asian staples to global supermarket fixtures. The oyster mushroom segment alone is forecast to grow at 11.5% annually through to 2033, the fastest rate of any mushroom category. Production acreage is following: in North America, growers increased their filling area by 22% in the 2024-2025 season compared to the year prior.
Behind this growth sits a quieter, more difficult story: the economics of actually producing mushrooms at scale are under acute pressure. Harvesting is estimated to account for up to 50% of a farm's total production costs in Western markets, and even on a broader accounting, staff represent around one third of production costs across the industry. Vacancy rates for mushroom pickers sit at around 20%, with annual labour turnover on commercial farms estimated at 40%. Training a new harvester takes up to six months. The work, crouching and picking in cool, damp growing rooms 365 days a year, attracts few volunteers even at relatively decent wages. About 20,000 people work as mushroom pickers across Europe, receiving between €0.10 and €0.50 per kilogram picked depending on country and product type.
The response from the technology sector has been to reach for robotics. Several well-funded startups are developing autonomous picking systems, and the broader mushroom equipment market is set to grow from $1.7 billion in 2023 to $3.2 billion by 2032. Full automation, however, remains commercially nascent for fresh-market production: mushroom caps bruise easily upon contact, and robotic systems capable of matching the dexterity and selectivity of a trained human picker are still maturing. For the foreseeable future, the baseline remains a person on a picking lorry; robotics are increasingly a supporting element in that equation, not a replacement for it. In that context, the quality, ergonomics, and maintainability of the lorry itself become the critical variable for any grower managing margins under pressure.
Industry observers have noted a significant increase in demand for semi-automatic picking lorries over the past two to three years, as growers seek tools that let one person do the work previously requiring two or three. The logic is straightforward: where full robotics cannot yet reach, a well-designed, low-maintenance, staff-friendly lorry reduces headcount requirements without sacrificing the quality that fresh markets demand. Beyond picking, the same pressure applies to bed preparation, compost handling, and growing room cycling. Each of these tasks represents both a cost centre and a point of quality risk if done manually and inconsistently.
Built from the Ground Up, in the Heartland of Mushroom Technology
This is the context in which a company like Mush Comb has been operating since the early 1990s, and the context in which its approach makes commercial sense. Based in Horst, Netherlands, the heartland of global mushroom technology since the Dutch Mushroom Cooperation was established in 1953, Mush Comb supplies machinery, climate systems, engineering, and equipment to commercial mushroom operations in over 50 countries. Mush Comb traces its origins to a mushroom farm, which shapes how it thinks about the problems growers actually face. That inside perspective is not incidental to the company's positioning; it is the foundation of it.
They have built farms in Netherlands, Saudia Arabia, Kazakhstan, Peru, South Africa, Switzerland, Spain, Romania, Iceland, Malaysia, Canada, France and beyond. What distinguishes Mush Comb's offer is less any single product than the philosophy behind its design process.
Every machine is built around one central question: what does the grower actually need?
The result is machinery engineered for simplicity. Fewer components means fewer failure points. Exposed bearings and accessible electrical boxes mean that cleaning, identified through the company's own analysis of service requests as the primary cause of equipment breakdown, can be done quickly and thoroughly.
From the Picking Lorry to the Exotic Container: Solutions That Work Today
The Compact+ Picking Lorry illustrates the design philosophy well. It was developed in collaboration with a Dutch grower whose brief was simple: build a lorry that works for the operator, not just the farm. The result is a rail-mounted unit controlled by a single person, praised by multiple clients for its ease of use and minimal maintenance requirements. The Premium Head Filling Machine, hydraulically and wirelessly controlled, automates the distribution of Phase III compost and casing soil during bed preparation at speeds of 6 to 18 metres per minute, removing the need to hire external contractors for the task.
Mush Comb was also one of the first supplier in the mushroom machinery sector to develop dedicated solutions for the exotic mushroom market, doing so in 2015 when most competitors were still focused exclusively on Agaricus cultivation. Oyster, shiitake, eryngii and enoki require specific climate conditions and substrate handling that cannot simply be adapted from button mushroom systems.
The mushroom equipment market growth is driven by the shift from artisanal to industrial-scale production across emerging markets. For growers navigating that transition, or established farms facing tightening margins and shrinking labour pools, the question is not whether to invest in better infrastructure, but where to find a supplier with the depth of experience to make that investment count.
For those attending, Mush Comb will be exhibiting at Mushroom Days 2026, taking place 22 to 24 April at the Brabanthallen in's-Hertogenbosch, the Netherlands.
