From Potatoes to Power

By District Energy posted 02-05-2021 14:32


Turkish foodstuffs producer Seydibey T.Ü.İ.E.T. has known for a long time that potatoes contain not just starch but also great potential. It processes around 70,000 metric tons of potatoes a year – and then sells them frozen in a wide variety of forms. A happy by-product of this is green electricity - produced with mtu gensets.

Whether it's french fries, croquettes, potato lattices or potato wedges – Seydibey products are popular with young and old. The company leads the market in this sector. All supermarket, restaurant and fast food chains in Turkey include the potato varieties in their assortments and menus. Seydibey T.Ü.İ.E.T. is a subsidiary of foodstuff conglomerate Konya Seker. Its production site is in the southwestern province of Konya, halfway between the cities of Seydişehir and Beysehir. So, it's no coincidence that its name is a cross between the names of the two cities. Since 2009, Seydibey has been processing potatoes there. 

For this purpose, the company has set up a biogas plant on its production site, turning the organic waste into biogas. An mtu 12V4000L32FB combined heat-and-power plant (CHP plant) then converts the biogas into electricity and heat at a rate of 1,169 kW per hour. The process really pays off, with the ability to produce 9,000,000 kW of electricity per year which is then fed into the public power grid. The Turkish government rewards the production of green electricity, paying 0.133 dollars per kilowatt. An integrated heat recovery system ensures that waste heat from the biogas plant is made usable

For this project, the mtu CHP selected was the "tropical variant" of the 12V4000L32FB model.This refers to the special robust qualities of the engine used. It is deployed in places where the temperatures are particularly high. And a good thing too, because even though the Turkish province doesn't have a tropical climate, temperatures can quickly soar in the summer.  

Back in 2013, parent company Konya Seker installed a biogas plant with an mtu CHP plant on another production site, one run on a combination of biogas and fossil-based natural gas. Now the plant has been transported to Seydibey and put into operation there together with the new unit. Both plants are now biogas-only.
