Omer's project, BioTreasure, helps people to use waste to overcome other challenges.
In Yemen, a lack of energy supply and food insecurity are major problems. Over one million families currently use firewood for cooking, which leads to deforestation. Omer is solving these problems in an innovative and sustainable way by enabling people to convert their bio-waste into both biogas and fertilizers for their farms.
Two environmental positives are the result: a reduction in methane from bio-waste and also in the number of trees being cut down.
