Using paper cups makes us more responsible towards the environment as most of them are biodegradable paper cups. Paper cups are basically made of paper after lining them with PLA coating or wax to make them waterproof. This paper is made with paper pulp which comes from turning the wood chips with a special process. So these cups become more decomposable in comparison to other disposables cups. PLA is Polylactic acid which is mostly produced with the plant based materials. PLA is obtained after the fermentation of starch which is produced from plants like corn, cassava, sugarcane or sugar beet.
