In a context where sustainability and resource optimization have become competitive drivers, agricultural by-products can no longer be viewed as simple waste. Converting them into useful and marketable materials opens a clear pathway to improving profitability and reducing environmental impact, fostering smarter resource-management models.

Here’s how 👇

Biomass residues in the agri-food sector

The agri-food industry generates large volumes of biomass residues, such as pruning waste, nut shells, and biomass from olive mills. For years, these by-products have been used as solid biofuel, leveraging their energy content.

However, when the goal is to maximize valorization, enhance sustainability, and support regenerative agricultural models, more efficient alternatives to traditional combustion emerge. One of the most relevant is biomass pyrolysis.

What is olive pit pyrolysis?

Pyrolysis is a thermal process that heats biomass —such as olive pits— to 350–700 °C in the absence of oxygen, preventing combustion. This process causes the material to decompose and primarily produces a carbon-rich solid known as biochar.

This approach enables the valorization of agro-industrial residues, reduces emissions associated with conventional waste management, and supports more sustainable and circular models.

Biochar from olive pits: properties and applications

Biochar is a stable carbonaceous material with high porosity and adsorption capacity. In the case of olive pits, its characteristics make it particularly valuable for agricultural and environmental applications.

Benefits and uses of biochar

Biochar derived from olive-pit pyrolysis is used to:

• • Improve soil structure and fertility
  • Increase water and nutrient retention
  • Act as a long-term carbon sink
  • Enable emerging applications in adsorption and new materials

Additionally, the biochar market is expanding, driven by sustainable agriculture, carbon capture initiatives, and the environmental transition. This makes its production a technically and economically attractive option for cooperatives and olive mills.

Environmental and economic advantages

Olive-pit pyrolysis offers a transformation pathway with clear benefits:

• • Reduced environmental impact
  • Long-term carbon storage
  • Better use of agricultural by-products
  • Potential to generate income through biochar sales
  • Lower waste-management costs

Rather than being treated as low-value waste, biomass can become a profitable and sustainable resource.

The SBS approach

At SBS, we support companies in assessing the valorization potential of their residues and making data-driven decisions. Our work includes:

• • Residue characterization
  • Laboratory-scale trials and testing
  • Technical and economic evaluation of valorization potential

Our goal is to identify the most efficient, sustainable, and high-value destination for each subproduct.
