DESIGN & DEVELOPMENT OF SOLAR POWERED COMPOST BIN LOW COST AUTOMATION & PACKANGING

Waste food has been a major concerning topic nowadays. Food that is wasted and put into garbage can be easily converted and used as compost for plants through this project. Also the decomposition of waste food which consumes large period of time is reduced and the energy used for conversion is harvested from solar system. So basically, this whole project is taking solar energy and using it to convert the organic waste in compost for better fertility of plants in less amount of time. When the waste food is inserted into the feeder, the food is been crushed into smaller pieces by the crusher. When the waste level exceeds the pre-decided level, the level detector will sense it and pass the signal to micro-controller. According to the information given by the humidity and temperature sensor the micro-controller will decide the period of time for which the heater should be ON. The heater will heat the material and make it dry. This dry material is compost ready to be used as fertilizer in plants. The gases which are produced during heating process are passed through a condenser where vapour’s are condensed and converted into distilled water which can be used in batteries. The whole energy required for crushing, heating and controlling is done by the solar energy harvested from the solar panel.”
