Based on ‘take, make, and dispose,’ the conventional linear economy has resource depletion and enormous environmental damage. A circular economy (CE) proposed to be achieved via reuse, recycling and regeneration, is resource efficient, waste reduction and sustainability. The circular economy has offered sales and marketing ideas in the era of artificial intelligence, as this chapter explores. The purpose of this chapter is to look into how organizations could focus on the use of circular marketing to improve the brand's reputation, customer engagement, and competitive advantage in the era of AI. Consequently, this chapter presents a focus on eco-branding, closed loop supply chains, consumer behavior in relation to consumption and sustainable product design. There are best practices and difficulties from organizations using CE driven artificial intelligence integrated marketing. Finally, the chapter closes with suggestions for keeping profitable and competitive by introducing circular economies in marketing and sales strategy.
