Terra à Terra is a project that promotes home composting at collective buildings, houses and in public or private institution’s, for the bio waste reduction on Lipor’s Municipalities. This project aims to promote a reduction in centralised collection and treatment of organic waste within Lipor's area of intervention, thus reducing the environmental impact of the process and improving the quality of life of the population it serves.

Lipor's associated municipalities (Espinho, Gondomar, Maia, Matosinhos, Porto, Póvoa de Varzim, Valongo and Vila do Conde), contribute with approximately 500.000 tons/year of municipal waste that needs to be collected, transported, treated and disposed. (Note about 40% of waste produced is bio-waste.)

Lipor helps the development of a composting site in residential area, providing compost bin (to all houses that have a garden inside the 8 municipalities already mentioned) and the opportunity to learn about composting, participating to the composting workshops.

Home or community composting is easy to be implemented at home and which has other advantages, such as physical activity, contact with nature, soil improvement and a better environment. Home composting is estimated to allow an organic waste reduction of over 459 Kg/year per composter, so with 12.211 composters implemented have a reduction potential of more than 5.600 tonnes of organic waste. Its diversion from energy recovery into composting will avoid the emission of more than de 985 t of CO2e per year.
