Umoe Bioenergy wants to not only produce clean renewable energy, but do so in an environmentally friendly way. This is done through an extensive reuse of byproducts, using wasps instead of pesticide when possible, preservation of the riparian forest, treeplanting and by limiting crop burning as much as possible.
In the process of producing ethanol there are a number of byproducts that we reuse. The vignasse from the ethanol distillation is used to irrigate and fertilize sugarcane crops. The filtercake from the sugarcane juice filtering and the ashes resulting from bagasse burning, are used as highly effective organic fertilizer and the bagasse from the sugarcane crushing is used in electric energy cogeneration. Instead of using pesticide to control the sugarcane borer moth, Umoe Bioenergy uses the wasp Cotesia flavipes which is a natural enemy and highly effective to prevent the spread of moths.
As a part of taking care of the local surroundings and the riparian forest, Umoe Bioenergy will over a 6 year period plant 560 000 trees. In the past two years we have already planted 250 000 trees from over 80 different native species. The area used for reforestation is approximately 20 % of the total land area Umoe Bioenergy uses.
Crop burning has been widely criticized, and Umoe has under the current owner limited crop burning as much as possible. We always prefer to use mechanical harvesting as it is better for the environment.
