HELSINKI, May 24 (Reuters) - Finnish refiner Neste Oil said on Thursday it will carry out a trial in the Stockholm area of its NExBTL biodiesel.
Neste said it work with the Swedish Post, Posten Logistik AB, shipper Waxholmsbolaget Angfartygs AB, Volvo Penta and Scania in the test.
The trial -- lasting from late 2007 to end 2010 -- will study how tailpipe emissions change with different levels of NExBTL blended into conventional fuel, Neste said in a statement.
