Q

what is flexible and responsible manufacturing

A

‘agile manufacturing’
is easily achieved through ‘lean’ manufacturing strategies; it allows manufacturers to change production with little notice and without complicated or expensive changes in the technological systems used. It means that manufacturers can cater for more customised products from small niche businesses and can respond quickly to changes in trends (or sales) by updating styles.

Q

what is extended producer responsibility

A

where producers (companies) are made responsible for managing the environmental impact of their products, particularly at the end of a product’s useful life. They are expected to ‘take back’ the product from consumers when it is no longer useful and put it back into the manufacturing of new products.

Developed to reduce the amount of waste and pollution going to landfill, limit the use of water and energy and lower greenhouse gas emissions during the manufacture of goods.
