Back2Buzz - Back2Buzz sells refurbished smartphones combined with eco-friendly & biodegradable accessories in order to reduce the electronic waste mountain.

By refurbishing smartphones, the lifespan is expected to be increased from 21.6months to 33.6 months, reducing the total CO2 emissions, keeping the smartphone in a better state (cover and protector glass), and possibly give the device a third life &; increase job creation. The upcoming project is to activate a buy back program in order to reduce the number of hibernating devices (estimated at 88% of the total volume sold) and to increase the refurbishment rate and to increase the material recovery rate. Any initiative to increase the recycling rate has a direct impact on the use of raw and precious material. The distribution model is focussed on B2B customers and telecom operators. Buying a refurbished device has the following indirect benefits: lower CO2 emission, less raw material, less pollution, less unhealthy labour by extracting raw material.

Key features

  • Giving a second life to a smartphone by extending its lifespan from 21.6 to 33.6 months, reduces the emission of CO2 by 20.3 million tonnes over a 10 year period
  • 700 million phones are hibernating. 84 million would be recycled with a 12% recycling rate.
  • For a 250g smartphone, almost 40 kg of raw material is needed.


  • Buying a refurbished device makes a saving from 30 to 40%.
  • Material recovery: if only today 12% of the total smartphones are recovered, the value of recovered gold, silver, copper, palladium, cobalt & lithium would be almost 36M$.
  • To refurbish 10000 smartphones, 8 jobs are created

Maturity Stage

  • Medium and large scale commercialization
  • Small scale commercialization
  • Initial market commercialization
  • Prototype testing in the real world
  • Prototype testing 1:1 in the lab
