SUPPLUS is a multi-functional relief supplies carton designed for refugees. When the carton is delivered to the local area, after taking out the items inside, it can be folded into a toilet to solve the health concerns and environmental pollution caused by the lack of toilets. The side inner layers of SUPPLUS contain vegetable seeds, and there is waterproof and rapid composting microbial inoculant coating at the bottom. When the interior of the toilet is being filled up with feces gradually, it forms a good natural fertilizer which penetrates the inner carton to nurture these vegetable seeds.
