AZURDUY, Sheila; AZERO, Mauricio  and  ORTUNO, Noel. Evaluation of Natural Activators Accelerating Process of Organic Waste Composting in the Municipality of Quillacollo. RevActaNova. [online]. 2016, vol.7, n.4, pp.369-388. ISSN 1683-0789.

In the municipality Quillacollo reaches 60 t d^-1 organic urban waste being 72.8%. They receive no treatment, so they raised the performing different treatments, in the Municipal Nursery Quillacollo, implemented as follows T1=activating TC (compost tea and ferment manure), T2 = activator BC (bone meal, cake soybeans, rice bran, molasses and biological), T3 = activator LC (yeast and molasses), T4 = activator EM (effective microorganisms), T5 = Witness 1 (cow dung), T6 = Witness 2 and T7 = Control 3 (pile outdoors). The results showed that activators favor the increase in temperature in short period. The plástic cover (T1-T6) kept constant moisture in compost piles, protecting high rainfall and preventing nutrient leaching. At 2.5 months, they managed to break treatments that more than 50% of the initial volume were T1 (57%) and T5 (52%), where T1 reduced 84% of the initial volume. The physical, chemical and biological characteristics of the processed compost, were rated the highest quality, because they favored the normal growth of the plant, which was verified with a bioassay. Economic analysis indicated that the treatments were T1 higher net profit (137.5 B), T7 (110.6 B), T6 (105.6 B), T3 (72.6 B) and T5 (29.8 Bs) . Therefore, the TC activator becomes the best organic activator that accelerates the composting process, generating greater economic benefits.
