Butterfly collection cart for waste recyclables: Ergonomics and sustainability

The definition of “waste” is presented as the remains of substances subjected to the action of several agents, such as ashes, which are the residue from combustion of firewood. According to Peltier and Sapota (2009), waste is an inevitable product of any life and consumption cycles. These authors argue that the daily habit of the humans in throwing away their waste had onset on the prehistoric era, in which they disposed of food remains at the same place they used to eat. (Eklund et al. 2010; Engkvist 2010a).
