In 2012 the company started the construction of an installation for biogas. It is an aerobic digester for agricultural and kitchen wastes. It also produces energy with cogeneration - electric and heat. The heat is used for greenhouse (and district heating which is in progress). The digested material is used as liquid fertilizer in the agricultural fields of the company and for the parks and gardens of the resort. The production goes directly to the hotels. A new biogas installation is under construction. The company has eco-policy implemented in all hotels and daughter companies which contains transport (buses and air transport, a construction company, etc)27.
At the beginning, they had problems using kitchen waste and started by using just agricultural residues. But after adjustments and improvements of the technology process, they are able to use both types of wastes, even though they use predominantly agricultural waste28.
