Hotel Tigaiga, Tenerife and Big Hanna are featured in ‘Buenos Días Canarias’


Hotel Tigaiga in Tenerife are presenting their Big Hanna composter in ‘Buenas Días Canarias’. 


Read more about Hotel Tigaiga and their work for a sustainable future:

Our establishment has a self-composting machine that transforms 50% of all organic waste generated by the hotel into compost, which is subsequently used to nourish 5,000 square meters of gardens. It is the first and only hotel in the Canary Islands to have this technology. The installation and commissioning of this self-composting machine has also been the result of an agreement reached with the City Council of Puerto de la Cruz and the waste management company Valoriza. The mentioned machine, BigHanna technology from Sweden, processes about 40 kilos per day, approximately 1,200 kilos per month, and the complete cycle of processing the waste into compost lasts about three weeks. It is a completely natural process that does not carry any external additives, but is based on the fermentation of the products itself.

Big Hanna is now installed at one of the largest gold mines in the world, Tasiast Gold mine, managed by Kinross.

Adding another country to our list, Mauritania (located in northwestern Africa) our distributor Berca Brand installed two units earlier this year at the Tasiast Gold mine. The mine is located 300 km north of Nouakchott, where the two Big Hanna’s are in full operation treating all food waste produced on site. The result, the final compost, is going to be distributed to the villages around the mine in order to improve their agriculture. This is a fantastic project, bringing back organic matter to help ‘Mother Earth’s’ recovery. The compost will optimize the function of the soil and restore depleted soils.

The goldmine area is very big and the base camp have two kitchen areas. One is called ‘Senior Mess’ and the other ‘Junior Mess’. The two kitchens produce food for the more than 3000 workers active in the different areas of the mine. In this case the challenge was to bring the food waste directly from the kitchen to the Big Hanna composters. Before putting the food waste into the composter the food waste is put in to a WMS (one installed in each kitchen) in order to remove the liquid from the food waste. The capacity of the WMS is about 300kg/hour. The WMS reduce the food waste both by volume and by weight. Each of the Big Hanna composters have a capacity to treat 170 kg of food waste per day. With the WMS units it was possible to increase the capacity of the Big Hanna by approximately 50%. 

Due to the difficult climate situation; sand, thunderstorms and a temperature over 40ºC all the year around, each machine has been installed in a 40 feet high cube sea container. For Kinross it is an optimal solution to have the composter in the back yard of the kitchens in containers. In order to make it more comfortable for the users and the maintance team, both containers haven been equipped with an air condition systems. For the Big Hanna’s air condition is not needed. The Big Hanna composters are now installed in 37 countries in nearly every climate situation, from the arctic areas down to sub-tropical areas. 

Big Hanna have been used to compost food waste on-site for more than 20 years in Sweden. The possibility to compost on-site for kitchens of this size is still a quite new experience in Mauritania. Our distributor will go back soon giving more training about composting and will also make some tests of the finished compost, already stored at the site.
