The fact that biowaste goes unprocessed and underused is a major problem worldwide. Biowaste causes both greenhouse gas emissions and nutrient loads in bodies of water. In addition, biowaste is stored in landfills or dumped into the environment all over the world. Giving up fossil energy and fertilisers made of virgin raw materials requires finding replacement products, and the reprocessing of biowaste could offer a solution to the dilemma. However, on a global scale, the energy or nutrients contained in biowaste are not yet being effectively recovered.
Solution: biowaste into biogas and fertilisers
Doranova manufactures biogas plants that process biowaste into biogas and fertilisers. The plants can minimise the greenhouse gas emissions of waste and reduce the loading they cause to water systems by efficiently fermenting the incoming matter. Doranova plants even enable the processing of the dirtiest of biowastes, such as manure containing stones and sand, which has caused major processing challenges in the past. Therefore, the solution might also have export potential.
Doranova’s revenue logic and benefits
Doranova and its subcontractors are selling their customers plant solutions and maintenance agreements. In the future, Doranova will also offer an option where it manages the plants in collaboration with a local partner. In addition to implementing the solution technically, upon a separate contract Doranova will also continue its involvement to guarantee the productivity of the plant with the customer, which reduces the customer’s risks related to payback.
Benefits to customers and end users
The customer is provided with a biogas plant that can be used for generating electricity, heat or carbon dioxide, or, alternatively, raw material for transport fuel. At the same time, it is possible to produce nutrients that can be recycled back to agriculture. Biowaste can thus be processed in an economically sensible manner that reduces environmental damage. The payback period of the plants is seven to ten years, in addition to which the customer can use Doranova’s employees in the construction of the plant, if it so wishes. This is particularly important to public-sector customers.
