While a circular economy (CE) paradigm shift has gained significant momentum among academics, practitioners, and policymakers, theory regarding its social aspects remains scant, especially theory based on an ethical, micro-level perspective. Circular consumption, referring to those consumption practices that aim to extend the lifetimes of objects and materials, involves ethical considerations. However, everyday circular consumption and its ethics have not gained a foothold in the CE literature. This article builds on the existing circular consumption literature by drawing insights from the posthuman feminist theorising of care, shifting the focus of care from humans to the complex relations between humans and nonhumans and conceptualising circular consumption practices as matters of care. This conceptualisation, which follows a thinking-with-theory approach, is based on empirical material constructed in two research projects focusing on frontrunner consumers in terms of circular consumption in Finland: food waste reduction and circular clothing consumption. We identify circular consumption as care by introducing three distinct perspectives: care as tinkering, care as affective practices, and care as ethico-political action. We show that approaching circular consumption practices as matters of care, while not always easy or straightforward, is an attempt to make consumption better: more attentive, inclusive, durable, and enjoyable. Our findings emphasise the interconnected nature of circular practices, the constant performativity of circular consumption, and nonhumans as crucial stakeholders in care relations. Consequently, we offer an alternative to technocentric CE perspectives and a way to promote a sustainable world through care.
