The issue of food waste has become an important global issue. All countries are working together to reduce food waste. Food waste causes impacts on health and environmental quality, as well as causes greenhouse gases which are linked to climate change. It is estimated that each year around the world there are food waste more than 1.3 billion tons. This amount equals one-third of the food produced worldwide, which produces around 8% of greenhouse gases.

The data from the Pollution Control Department indicated that food waste in Thailand in 2017 accounted for 64% of the total amount or 254 kilograms per person per year. Food waste was utilized in a very small percentage because there is no proper waste separation. In Bangkok, only 2% of food waste was recycled. In addition, there is no separation of waste before disposal. That makes food waste mixed with other types of waste. As a result, other types of waste, such as plastic waste and packaging waste cannot be utilized as well. This causes the country’s recycling rate to remain low.

Therefore, proper food waste management will have direct and indirect positive effects on the solid waste management of the country and will contribute to the improvement of the environment quality and natural resources. In addition, it will promote economic development at the grassroots and commercial levels, while rendering the co-benefits to the ecosystem and human health.
