Kilimanjaro engages in the waste oil recovery sector and replaces petrochemical diesel with biodegradable, nontoxic fuel produced from recycled cooking oils. They collect used cooking oil from restaurants and hotels, which they then process to sell it to traders and biodiesel manufacturers internationally.

Upstream oil production, which involves drilling and operations to carry crude oil to the surface, is commonly carried out near human settlements. There are nearly 40,000 oil fields in the world, with 6 million people living or working near them. Oil extraction may have an effect on local soil, water and air, affecting community health.

The Moroccan company, Kilimanjaro, provides points of sale with standardized drums to collect oils from firms who engage in the catering sector. The stakeholders have a multitude of channels to send collection requests via an online application or phone. At each collection, Kilimanjaro gives necessary information about the collection and sends frequent reports on the recovery of the oils and the impact on the environment to ensure a transparent supply chain. 

During the processing and transformation of cooking oil into biodiesel the amount of water usage and carbon emissions decreases compared to fossil fuel: When 1 litre of oil is recycled, 1 million litres of water are saved and 88% fewer greenhouse gases are produced. For the future, Kilimanjaro aims at increasing its level of engagement with cafés, hotels and restaurants to double the annual collection potential.
