Generating billions of dollars every year, the fashion industry is one of the biggest markets around - and it has an environmental impact to match.

Manufacturers all over the world discard tonnes of fabric and pollute water during production.

Christina Dean, the founder of the NGO ‘Redress’, is hoping to tackle these issues by encouraging manufacturers to make the most of their factory textile waste.

One brand has already produced a t-shirt made using recycled cotton scraps and polyester that uses 74 percent less water and generates 53 percent less greenhouse gas than an ordinary cotton t-shirt.

Divya Gopalan is in Hong Kong to see how 'Redress' is helping China’s huge manufacturing industry cut its waste and embrace the business case for environmentally-friendly fashion.
