Sour Cherry Stone Fuel Supply
Sour cherry stones are a high-calorific by-product of fruit juice and frozen-fruit plants, and their small, even size lets them be fed automatically like pellets. Biyolink verifies dried sour cherry stones with laboratory analysis and delivers them to industrial plants in bulk or in big bags — and buys from plants that have stones to sell.
What Are Sour Cherry Stones and Where Do They Come From?
Sour cherry stones are the hard stones separated from the fruit at plants that process sour cherries into juice, frozen fruit, jam and canned fruit; each holds a small kernel. Fresh stones from the plant carry fruit residue and moisture, so they are washed and dried before being sold as fuel.
In Türkiye sour cherry production is concentrated in Afyonkarahisar, Konya, Kütahya and Ankara, and a large share of the crop is processed into juice. The harvest is in June–July, and that is when the stones come out. Dried stones keep well, so stock is built during the season for year-round delivery.
Typical Technical Values
| Property | Typical value |
|---|---|
| Net calorific value | About 4,000–4,600 kcal/kg depending on moisture |
| Moisture | 6–12% (dried); higher in fresh stones |
| Ash | About 1–1.5% |
| Particle | Small, even stones; flow easily on screw feeders |
| Form | Bulk, whole stones |
These are typical ranges from published sources; actual values vary by lot, source and moisture. We share a laboratory analysis of every lot with our quote.
What Are Sour Cherry Stones Used For?
The kernels yield cherry kernel oil used in cosmetics, and cleaned, dried stones are used as filling for heat pillows. In industry they are a fuel: the calorific value is high, ash is low and the small, even stones can go into pellet boilers without pre-treatment. A boiler not set up for them may lose efficiency, so feed and air settings should be adjusted to the stones.
- Pellet and multi-fuel boilers
- Steam and hot-water boilers (food, textiles)
- Greenhouses and drying plants
- Additive to sawdust pellets and blended fuel
Transport and Delivery
Dried sour cherry stones travel in bulk on tipper or walking-floor trailers, or in big bags; the small, free-flowing stones unload easily into silos and screw conveyors. Damp stones left in a pile can go mouldy, so they should travel dry and be stored indoors in a ventilated space. Every shipment is recorded with a waybill and a weighbridge ticket.
What Determines the Price of Sour Cherry Stones?
The price per tonne is not fixed; it changes with the season, how dry the stones are and the lot. We build our quote around:
- Moisture and ash (laboratory analysis)
- Fruit residue, stalks and foreign matter
- Volume and delivery schedule
- Distance to the delivery point and form (bulk or big bags)

Frequently Asked Questions
What is the calorific value of sour cherry stones?
Published sources give dried cherry stones a net calorific value of about 4,000–4,600 kcal/kg depending on moisture. It varies with moisture and fruit residue from lot to lot; we share a laboratory analysis of every lot with our quote.
What are sour cherry pits used for?
In industry mostly as fuel. The kernels yield an oil used in cosmetics, and cleaned, dried pits are used as filling for heat pillows. This page is about sour cherry stones used as fuel.
Can cherry pits be burned in a pellet boiler?
Dried cherry pits are small and even, so they can be fed into pellet and multi-fuel boilers without pre-treatment. A boiler not set up for them may lose efficiency, so the feed and air settings should be adjusted, and you should check that the boiler manufacturer approves the fuel.
Can stones from a juice plant be burned straight away?
Fresh stones carry fruit residue and moisture: as they are, their calorific value is low and they can go mouldy in a pile. They need washing and drying before use as fuel. We supply dried stones with an analysis.
Are sour cherry stones available all year?
The stones come out in the June–July processing season. Dried stones keep well, so year-round delivery is possible; for regular orders we plan stock and the delivery schedule at the start of the season.
