Abstract

The vegetable lignocellulosic residues of the Universidad Industrial de Santander campus were physical, chemistry and microbiological characterized and biodegraded for wormcompost production. They were studied the effect of some variables such us air circulation and microorganism addition. These microorganisms were native acceleration products. The lignin and humins reduction presented significant differences. The biodegradation process generates more humic and fulvic acids when the vegetable residues were treated with air (overturning) and with microorganisms addition. Additionally, it was observed strong pathogenic microorganisms reduction, with pH increase, improvement of the plasticity and a regulating effect of the nutrients in the soil. In taking account the results from pilot plant, we had building a compost plant with 51 m3 of capacity.
