Dehydrated Food Waste and Leftover for Trench Composting.

The growing global population has a persistently negative impact on the economy and
ecology due to food waste. This topic has recently received much attention from around
the world. For both homes and the food processing industry, recycling food waste is
crucial to waste management. This study aims to show how dehydrated food scraps and
leftovers can be used as raw materials for trench compost to enhance soil quality and reduce
leachate and greenhouse gas emissions.
The results showed that the pre-treatment
and air temperature significantly affected
the finished trench compost products’ EC,
pH, and nutrient content. Pretreated dried
leftover at 80°C after trench compost was
found to have the highest value of CNH, S
(36.53%), and micronutrients (0.103404%)
when compared to micronutrients in the
final product of pre-treatment dried leftover
at 80℃ after trench compost that was
(0.057273%). Dehydrated leftovers from
trench compost were thought to have nutrient content that would improve soil quality, slow decomposition, and reduce odor,
thus enabling more frequent trash collection.
