Sunshine Kaidi (Finland) New Energy Co. Oy (Kaidi Finland) is an energy company that plans to build a biofuel refinery in Kemi, Finland.

The planned refinery in Ajos, Kemi would use second generation biofuel technology, such as plasma gasification, syngas cleanup and the Fischer-Tropsch process. Plasma gasification involves heating the processed material to a notably higher temperature than in other gasification methods, making it more suitable for the processing of demanding materials, such as wood. The process increases the efficiency of the feedstock.

The Fischer-Tropsch process is a catalytic chemical reaction, where carbon monoxide and hydrogen are transformed into liquid hydrocarbons. The catalysts are iron and cobalt based and speed up the chemical reaction in certain temperatures. The primary function of the process is to produce a synthetic oil replacement to be used as a synthetic lubricant or fuel. The process was invented by Franz Fischer and Hans Tropsch in the 1920s as a way of producing liquid fuel.

Second generation biofuels refer to fuels that use municipal solid waste and materials high in lignocellulose content in their production.
