This Life Cycle Assessment (LCA) aims to evaluate the environmental impact of the production of candlesticks. All the different materials and processes required to manufacture candles need to be taken into consideration to determine the impacts on the environment. The most common material used to manufacture candles is paraffin wax. Each candle comes in some type of individual packaging most of the time. Candle wicks are made using various natural fibers, such as reeds, rushes, or cotton. An important refinement in wick technology introduced the plaited wick, which burned more than unplaited wicks. Currently, twisted or plaited cotton makes up most of the wicks. The candlestick is made of steel, or could also be made of metal. The functional unit will be a 125ml candle able to generate up to 25 hours of light. Each steel-made candlestick can only hold one candle, and can be used several times.


Paraffin wax
Materials for packaging

Gas emissions: when candles burn, paraffin wax emits greenhouse gasses such as carbon dioxide. •Depletion of natural resources: paraffin wax is derived from crude oil. Paraffin candles are petroleum products, a non renewable resource. It could increase pollution due to oil spills and the processes needed to extract petroleum. At the same time, the extraction of metal needed for the candlestick causes large volumes of solid waste, requires large amounts of energy, and produces air, soil, and water pollution. •Chemicals toxicity: some candles might have lead or zinc in their wick, which release harmful gasses when they burn. Also, scented candles can release toxins from the chemicals used to give them scent.
