I wish you best in expanding your effort because access to sanitary products for every women is part of their basic rights which is not even acknowledged well. Balancing environment and product at scale is not something present in the sector now. Congratulations for figuring that out.
Given all the refugee crisis increasing around the world, your idea sounds very good. Best wishes for you to figure out the solutions which then can be replicated in the other camps for the ones who need it the most.
