European and national policies on waste management have for some years been encouraging recovery of waste rather than its elimination. Composting consists of the biological, aerobic (in the presence of air) and thermophilic (needs high temperatures) process through which micro-organisms act on the biodegradable material obtaining compost as a result, which is a product that can be used as fertiliser in agriculture and gardening. The process can take between 8 and 12 weeks. Growth was observed in this activity with respect to previous years both in production and in the number of plants. This trend is endorsed by the clear market tendency to reward recovery compare to elimination.
