Waste Management and Territorial Impact in the Canary Islands

Abstract

Insularity presents several challenges in the development of Europe’s outermost regions. In the case of the Canary Islands, one of these challenges is waste management, which faces a series of difficulties inherent to territorial disparities, including land use and availability, a high percentage of protection, a large number of annual tourists and a high level of product imports. The archipelago is made up of eight islands, and waste management is significantly different in the two capitals, Tenerife and Gran Canaria, and the rest of the smaller islands. European targets for adequate waste management have not been achieved in those areas. As an example, only 16% of the collected waste is recycled currently, mainly due to a lack of infrastructure and a lack of agility on the part of the corresponding institutions. There is also pressure exerted on this sector by tourism, which accounts for approximately 40% of employment in two of the islands. As a general conclusion, valorized waste management is proposed, where the use of by-products, such as biogas or compost is implemented in sectors where they can be used, i.e., as electricity, potentially of 19 GWh/year, and agricultural supply, thus promoting recycling and the circular economy in the Canary Islands.
