No Waste of Time, or Energy

Seeking Sustainability and Reducing Fossil Fuel Dependence

Innovative approaches aim to enhance sustainability and lessen reliance on fossil fuels. Remarkable headlines have emerged, including studies exploring cow dung gases for cleaner energy via anaerobic digestion.
In Seville, 48,000 trees drop 5.7m kilograms of inedible fruit, posing hazards and demanding a substantial cleanup operation.

Seville’s water company trialed electricity production from fermented orange methane.

Electricity from Biogas

Excess oranges undergo juice extraction for electricity generation from biogas. The surplus waste is transformed into fertilizer for farms.
Through anaerobic digestion, wastewater organic matter is stabilized, generating methane-rich biogas for cogeneration engines, producing electricity.

Energy Self-Sufficiency

EMASESA’s CEO, Jaime Palop, states, “The project aims for energy self-sufficiency in urban wastewater treatment.” The facility already generates power from organic matter.
Anticipated production at the plant is around 1,500 kWh, equivalent to 150 homes’ consumption. If the city recycles all wasted oranges, it could power 73,000 homes.

Excess Electricity for the Grid

By 2023, surplus electricity will be integrated into the grid.
Seville’s mayor, Juan Espadas Cejas, commends Emasesa as a sustainability role model in Spain, leading the charge against climate change.

This illustrates how industry leaders can innovate, turning a problem into a solution, converting littered oranges into energy for 73,000 homes.
