Mustafa Elalami et al., International Journal of Emerging Trends in Engineering Research, 8(7), July 2020, 3777 - 3783 3777 ABSTRACT This article describes the importance of using the most efficient and quickest means to treat organic waste, in this work we presented the design and realization of an automated machine that produces compost for 4 weeks with the reduction of 80% of the products per day in the city, in fact this technique will be an effective tool for provincial managers, and can be used on a small or large scale. As well as the remote control technique based on the communication between the remote database MySQL and the arduino UNO card and wifi module EPS8266, this exchange allows to control all the parameters of the composting process through a web application that presents these data in different forms, therefore the handling of the composter becomes more and more efficient and easy. Key words : Design smart, rotary composting, remote control, database, web server 1. INTRODUCTION In Morocco, as in all developing countries, land filling is the most commonly used method because of its lower cost and simplicity. However 75% of the organic matter is found in the large amounts of waste that occur daily. Therefore, one of the primary causes for global warming is the spread of carbon dioxide and methane biogas, which are generated due to the natural decomposition of organic waste in landfills in the absence of oxygen levels. This leads to the production of the leachate flow that negatively influences water tables. To solve this problem, there are many waste treatment techniques, among them composting, which is considered the best method because of its advantages, which allows the recycling of organic waste into better quality fertilizers [1], [2].Composting is the best solution to reduce the negative effects that result from the propagation of organic waste on soils by transforming organic waste into mature compost, using the degradation fields of macro- and micro-organisms. Indeed this method is commonly used to produce organic fertilizers from organic waste that is rich in mineral compounds such as nitrogen, phosphorus and potassium [3]. Among the physico-chemical factors that impact the composting process are aeration, temperature, humidity and particle size. Composting is a heterogeneous and biochemical process based on the mineralization of carbon dioxide materials, Ammonia, Water with incomplete hydration to produce a stable product with reduced pathogenic toxicity [4],[5],the achievement of this process depends on good management, which relies on monitoring, control to obtain real-time information [6]-[7]. Therefore, a successful composting operation requires good C/N (carbon/nitrogen content) mixing ratios, aeration rate [8], [9] to maintain the moisture content between 40% and 60% [10] and temperature control during the composting phases (mesophilic phase (20° to 45°) and thermophilic phase (45° to 65°))[11]. There are several methods of composting such as small-scale composting, compost pile which consists of putting the organic waste in an open air space, pile in container compost is used to put the waste in a closed container, barrel compost is used to put the organic waste in a rotating cylinder, trench compost is used to dig a hole in the ground and put the organic waste, worm compost is a decomposition process using various species of worms, white worms and other earthworms. Others of large scale such as aerobic windrow composting which consists of placing a mixture of raw materials in long narrow heaps that are stirred or turned regularly. To speed up the composting process, if a rotating system with active aeration is used to reduce the composting time [11], [12],[13]. Previously, all composting parameters were monitored from time to time by humans. This leads to a delay in composting management and control, therefore the monitoring system has developed new technologies through the use of sensors. The compost heap was designed as a rotating cylinder with a temperature sensor, a moisture sensor and a mechanical rotation system to stir the compost [14]. After these techniques came into play. Today, the monitoring System applied to static composting has been designed with GSM/Bluetooth technology to monitor the process remotely.
