Method & Evidence

AimTo investigate the feasibility of achieving zero CO2 emissions from energy use in olive pomace plants in Crete, Greece, through the integration of solar PV technology.
MethodQuantitative analysis and techno-economic assessment.
ProcedureThe study analyzed the energy consumption patterns of a typical olive pomace plant in Crete, identifying that 99.1% of energy is used for heating and 0.9% for electricity. It assessed the potential of using olive kernel wood (a byproduct) as a carbon-neutral fuel for heat. The research then calculated the electricity demand and the required solar PV system size to meet this demand, considering Greece's net-metering policy. Finally, it performed a techno-economic analysis to determine the capital cost, payback period, and net present value of the solar PV installation.
ContextIndustrial processing of olive byproducts (olive pomace) for energy and oil extraction.

Design Principles

"Maximize resource utilization and minimize environmental impact through integrated renewable energy systems."

This study highlights a practical pathway for industrial facilities to achieve net-zero energy emissions. It demonstrates how waste products can be leveraged for energy and how renewable energy sources can be integrated to eliminate reliance on fossil fuels, aligning with global sustainability goals and offering a model for other industries.

06

What This Means for Your Design

Factories that process olives can become completely 'green' in terms of their energy use by burning the leftover olive pits for heat and putting solar panels on the roof to power everything else. This makes them not add any carbon dioxide to the atmosphere from their energy.

How to use in your project

  • 1.Use as a case study for a project aiming to reduce the environmental impact of a product or system.
  • 2.Cite as evidence for the benefits of renewable energy integration and waste valorization.
  • 3.Inform the design of energy systems for prototypes, especially those aiming for eco-friendliness.
