Summary

A group of engineering graduates designed and implemented a highly innovative project in the central area of the Island of Malta (Ħaż-Żebbuġ). It consisted of setting up and equipping a hi-tech hydroponic greenhouse which integrates other organic practices from aquaculture, Korean Natural Farming, Regenerative Agriculture and the Integrated Aqua-Vegeculture System (IAVS) method for producing vegetables and fish. The innovative combination of these production methods saves energy, water, fertiliser, and labour.

Results

The greenhouse can produce approximately 1 tonne per week of vegetables and 4 tonnes per year of fish, using waste products as inputs (fertilizers, food etc.).

Rainwater provides for almost 90% of the greenhouse’s needs and water is prevented from percolating nitrates and sulphates into the water table.

Vertical space techniques increase the number of crops per m2 and reduce use of synthetic nutrients by 95%.

Some 98% of the farm’s energy needs are met with renewables.
