This chapter examines the entanglements between two seemingly separate economies, women’s promotion groups―grassroots arrangements bringing together self-employed women around shared activities to sustain their livelihoods―and bauxite refining. It starts by following the circulation of caustic soda, a chemical agent harmful to humans and used in soap making, fabric dyeing and aluminium production from bauxite, in and around the refinery of one of the leading aluminium companies in the world. The main argument is that diverse economies such as these women’s groups are significantly shaped by and sustain the bauxite industry, with which they are in mutual constitution and tension. Drawing on original interviews with members of these groups, civil society, and government representatives in Guinea, the analysis demonstrates that the bauxite industry directly sustains women’s promotion groups, both through the smuggling of caustic soda by factory guards and through corporate social responsibility initiatives. In turn, the groups subsidise extractive operations in times of crisis and factory closure, with many women becoming the sole income earners in their families and bearing the double burden of production and social reproduction. At the same time, women’s groups elude extractivist logics; they represent a terrain where resilience, solidarity, and sociality can emerge. Attending more closely to how they are entangled with extractivism is important, not only to make them more visible as sites of enquiry and development policy, but also to advance alternatives to extractivism that are more just and sustainable.
