Previous packaging outer box and Current packaging inner box 3 g of ink is required per m2 of packaging [1]. Previous packaging inner box Any products made in Guangdong province have travelled 200 km to reach the factory location in Guangdong province. Previous packaging inner box and Current packaging tissue paper An average 20 ft shipping container was used, weighing 2.2 tonnes [2]. Previous packaging inner box The Polybag used to package the product weighs 0.025 kg. Previous packaging inner box The corrugated bulk outer box for distribution weighs 0.2 kg. Current packaging tissue paper The paper packaging for distribution weighs 0.1 kg per ream. Current packaging tissue paper 10 pallets of product per 20 ft shipping container [3]. All products All packaging of products is recycled at THG facilities. All products The weight of a wooden pallet is 22 kg [4]. All products The end-of-life waste treatment is based on EU averages [5]. All products Based on primary data from one supplier, a 15% scrap rate was assumed for the production of all products. All products Due to the lightweight nature of the products, distribution via shipping was assumed to be with a bulk carrier, with the additional weight of the containers added separately. All products A weighted average distance was used to calculate the emissions of distribution to THG warehouses from Secondary supplier locations. All products A weighted average distance was used to calculate the emissions of distribution to the end customer from THG warehouses.
