Designers are envisioning new typologies of products aiming for instance to extract CO2 from the environment or creating products from landfill waste, in this context a fundamental question arises; what could be a philosophical framework for a subtractive practise in design? In this paper the notion of Deep Products is introduced by building from notions of Deep ecology, Deep Design, and stewardship. This theoretical proposition addresses the design of products from a life-cycle perspective through contemporary notions of subtraction-by-design. The model presented transitions design to a model demanding extended projects considering every aspect of the life-cycle of products, from inception to deployment, while addressing issues of impact and reuse with the characteristic of subtraction-by-design. In this context, undisciplined stewardship is introduced as an ethical responsibility principle to enable the creation of such products by building from notions of personal responsibility, alterplinarity, and stewardship.
