Pollution is a significant environmental issue that continues to have profound effects on human health and the planet’s ecosystems. One notable source of pollution is greenhouse gas emissions, which contribute to global climate change. Composting, a popular method of organic waste management, has the potential to reduce pollution by diverting waste from landfills and producing a nutrient-rich soil amendment. However, the environmental impact of composting is not well understood, particularly in terms of greenhouse gas emissions. This article proposes an IoT system to monitor the data of different greenhouse gases, temperature, and humidity of a compost pile to know the carbon footprint during the composting process and even reduce it by modifying the process thanks to real-time monitoring of the parameters of interest.
