Despite its characteristics such as greater energy efficiency and life expectancy in comparison to incandescent lamps, fluorescent lamps contain toxic residues which may contaminate the environment in case of inappropriate discard or accidents regarding its handling and transportation. FLC sustainable, beyond a mere package, proposes a new kind of relationship between the consumer and the compact fluorescent lamp package by facilitating the return of the replaced, old or damaged bulb to its manufacturer and its due recycling. The package, composed mainly by a molded paper pulp case, besides protecting efficiently the new lamp from the point of sale to its place of use, acts as a protective structure for the inoperative lamps, which can therefore be discarded safely in domestic waste or forwarded to a proper waste collection point.
