In 17 months of work, 5 technologies were technically and economically evaluated allowing recovering sludge and ashes. Better-evaluated technologies were: a fertilizer developed based on ashes and sludge, and the manufacture of particleboards based on pine chips and sludge. Sludge and ashes showed a significant contribution in soil nutrients, such as phosphorus, potassium and calcium, among others; boards made from chips and sludge were found to have a higher tensile strength and a lower swelling percentage than boards made only from chips.
The event will take place on May 23, 2013, between 9:00 am and 12:30 am at the Auditorium Jaime Baeza located in the EmpreUdeC Building of the Universidad de Concepción.
