The project addresses three distinct environmental problems which require attention both at global and local scale: land degradation, increasing amounts of waste from orange processing, and large amounts of waste sulphur. Estimates indicate that 38% of land cultivated worldwide has been damaged by conventional agricultural practices, involving soil compaction, loss of organic matter and erosion. Every minute, the world loses 3 ha of arable land due to salinisation and alkalisation and approximately 25 million ha of irrigated land has decreased productivity due to inappropriate soil management. In parallel, according to the European Environment Agency, 8% of the European territory - about 14 million ha - already shows some degrees of desertification, a situation particularly serious in southern EU areas. Citrus is cultivated in southern Europe, and quantities produced have increased steadily in the last decades. This growth has involved also the processing industry, with some serious negative environmental impacts, considering that only around half of the fresh orange weight is eventually transformed into juice, generating great amounts of residue, which is sent to landfill in large part. The third problem is due to the large amounts of elemental sulphur recovered from gas and oil desulphurisation, which - although in part reused in industrial applications - in large part remains unutilised and goes to landfill, so representing a potential environmental threat. ... for more info please visit https://webgate.ec.europa.eu/life/publicWebsite/project/details/5601
