1. Description of the challenge

Bolsius invites students to develop a completely wasteless and CO₂-neutral candle (when burned) for our current Bolsius Cleanlight collection. The Cleanlight system includes a glass holder and a wax refill with a wick. The only part that creates waste is the wick plate, which holds the wick in place. Right now, consumers need to remove this piece before they can safely refill the candle, making it the only physical waste in the product. The goal is to create a refill candle for our Cleanlight system that is primary 100% wasteless and secondary 100% bio-based, without compromising the emotional and symbolic value of candlelight.

Why this challenge?
As one of Europe’s leading candle manufacturers and a proud B Corp, Bolsius is committed to shaping a better future. Candles are deeply connected to emotion, rituals, and atmosphere, but they also involve raw materials, energy, and emissions. How can we minimize this impact while preserving the magic of candlelight?

What to consider:

  • Technology & Materials: What innovative waxes, wicks, or packaging could help eliminate waste and reduce or neutralize CO₂ emissions?
  • Usage & Logistics: How would your concept affect user experience, safety, production, or distribution?
  • Impact & Feasibility: Is your idea scalable and realistic within current or future manufacturing capabilities?
  • Experience & Symbolism: Can your candle still offer comfort, ambiance, and connection in the way people expect?
