“…The composting process can be shortened should the pile turning be conducted with an optimized frequency (instead of once per fortnight) [ 41 ] at the expense of higher manpower and advanced machinery. In-vessel composting [ 42 , 43 ] could be a promising alternative to open-air composting due to its closed system where feeding, temperature, and mixing can be monitored and controlled. The integration of intelligent elements into the composting process [ 44 , 45 ] would be a future trend for process improvement, especially in terms of composting duration and compost quality.…”

This work demonstrated the feasibility of an industrial-scale aerated static pile composting system for treating one of the common biowastes—soybean curd residue. The mixing ratios of the feedstock were optimized to achieve a carbon–nitrogen ratio and a moisture level in the ranges of 25–35 and 60–70%, respectively. This open-air composting system required 6–7 months to obtain a mature compost. Solvita and seed germination tests further confirmed the maturity of the compost, with 25% compost extract concentration yielding the best germination index in the absence of phytotoxicity. The bacterial and fungal compositions of the compost piles were further examined with metagenomic analysis. Thermoactinomyces spp., Oceanobacillus spp., and Kroppenstedtia spp. were among the unique bacteria found, and Diutina rugosa, Thermomyces dupontii, and Candida taylorii were among the unique fungi found in the compost piles, suggesting the presence of good microorganisms for degrading the organic biowastes.

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.

“…However, many specialists have different opinions about both technologies (Sołowiej et al, 2017;Czekała et al, 2019;Ermolaey et al, 2019). Some of them underline that closed chambers make easier control of the whole process (Jiang et al, 2019). And other researches showed the big advantages of windrows composting, especially easier mechanization processes and deep mass losses (Bhattacharjee et al, 2016).…”

EU forestry does not currently have automatic planters, hence the project proposes to develop an innovative technology in which the key role will be played by an autonomous planter designed for establishing forest cultures and afforestation of former farmland and reclaimed areas with the use of seedlings with a covered root system (grown in container nurseries). The device will have a self-levelling traction system, a control system with a satellite navigation module to support autonomous navigation and planting site selection, a mechanism of planting spot preparation, a planting unit, an intelligent robotic arm to feed seedlings from containers to the planting unit according to a given algorithm, a container storage unit with an automated feeder, a drive unit with an electro-hydraulic control system, a control module, and a wireless remote control system. The autonomous planter will significantly reduce the cost and machine inputs during establishing forest cultures and afforestation of former farmland and reclaimed areas with the use of seedlings with a covered root system, and thus perfectly fits into the assumptions of agriculture 4.0.
