Global Esco introduces an innovative circular economy solution for olive oil production waste: we transform the residues into organic fertilizer, irrigation water, renewable energy, and carbon credits. This approach reduces environmental impact while increasing income for olive producers.
Market Need
Over 1.5 million tons of olive mill wastewater and solid residues are produced annually in Greece—materials traditionally treated as waste, incurring high environmental and financial costs. Meanwhile, the organic fertilizer market in Europe is growing at over 7% annually, presenting strong development opportunities.
Transformation into Organic Fertilizer
Through biological, mechanical, and thermochemical processing (carbonization), olive solid residues are turned into biochar—a carbon-rich, highly porous material. One gram of biochar can have the surface area of two tennis courts!
Benefits of this organic fertilizer:
Enriches soil with organic matter
Improves soil structure and fertility
Retains 4–5x its weight in nutrients and water
Reduces need for chemical fertilizers
Saves irrigation water in agriculture
Production of Irrigation Water
Olive mill wastewater is treated through high-performance separation systems and biochar biofilters to produce clean water suitable for irrigation.
Carbon Removal Credits (CORCs)
Using internationally certified carbon removal technology, the process generates valuable Carbon Removal Certificates and renewable energy.
Overall Benefits
Reduces environmental footprint of olive mills
Promotes sustainable agriculture
Adds value to agricultural waste
Prevents soil and water pollution
Produces both organic fertilizer and irrigation water
Enables carbon sequestration and soil enhancement through biochar
Offers energy-efficient, autonomous operations
Strengthens producer income with added value
