The triple bottom line is a product development philosophy that takes into account the social and environmental impact of a product, not just its financial cost. The goal is to create products that are sustainable and have a positive impact on the world. This can be accomplished by using eco-friendly materials, manufacturing processes that minimize waste, and packaging that can be recycled or reused. In addition, products should be designed to last long enough to justify their purchase price, and they should be easy to repair or upgrade when necessary. By considering the triple bottom line, companies can create products that benefit both people and the planet.
