Industrial residues continuing being and economic problem so companies have to assume high costs to manage them. Such is the case of large amounts of fruit residues produced in Medellín, city and surroundings due to a great number of companies of this agroindustrial sector. In this work a scan was made in Medellín and the South of Valle de Aburrá to know the current problem of these residues. Subsequently a physical-chemistry characterization of the most representative residues with the purpose to propose different alternative uses. The main residues of the interviewed companies come from orange, guava, guanabana and mango. The main valorization processes include compost, worms culture and obtaining chemical products. Only with the interviewed companies, plants of waste valorization could be mounted with prosecution capacity from 9 to 375 ton/month depending on process. If all of the residues generated in Medellín and the South of the Valle de Aburrá were used, the capacity of these valorization plants could multiply for 20.

Palabras clave : Shells of fruits; agroindustrial residues; biological valorization; thermal valorization; compost.
