Advanced Recycling Technology (ART) Laboratory adopts the concept of "urban mining" to develop the technologies for recovering valuable substances from wastes in our daily life, thus promoting the sustainable circulation of resources. The wastes that ART lab studies include incinerator ashes, ferrous and non-ferrous slags, industrial sludges and dusts, agricultural wastes, e-waste, etc. ART lab has tried to reverse the bias against recycled materials (e.g., low-quality and low-value) and attempts to develop functional or high added-value materials. ART lab suggests that everything is resource if we can properly separate or transform the wastes into useful materials. Anyone interested in this idea is welcome to join ART lab~
