Composting of solid waste from the coffee milling process using trench composting and a bioreactor with the help of efficient microorganisms in the Libre University, Socorro headquarters

Introduction: The present article is the product of the research “¿Use and management of organic waste from the Majavita farm, Universidad Libre, Socorro Headquarters (Santander)?" carried out during 2017 and 2018 in Socorro, Santander. Problem: Currently the Libre University, offers to solid waste coming from the benefit of the coffee a management in a trench compost system to prevent contamination that is caused for it poor disposal; this does not imply the production of an optimum product that shall have the standards of quality of a suitable compost. Objective: Propose an alternative to operate the compost process under suitable conditions of the process variables; it is expected that would allow waste to compost more efficiently and in less time. Methodology: This article compares the effectiveness of composting production in a traditional trench system against a semi-closed bioreactor system, and the cost-benefit of implement this proposed system. Results: To guarantee the result by showing the improvement of the process; is necessary to follow and compare the behavior of the process variables in each kind of composters, such as temperature, moisture and ph. Conclusion: This project seeks to propose a viable alternative for the treatment of the solid waste of the productive process of the coffee. Originality: This research, seeks to improve the process of compost in the Majavita Farm. Limitations: The time used to the farm to compost the solid waste using a traditional system.
