16/09/2011 (Reuters) - Nestle , the world's biggest food group, has resumed palm oil purchases from Sinar Mas Agro Resources and Technology (SMART) , the Indonesian palm oil firm said on Thursday.

SMART, which runs the Indonesia palm oil operations of its Singapore-listed parent Golden Agri-Resources , was given a mixed score card last year in an independent environmental audit after Greenpeace accused the firm of clearing peatland and forests that sheltered endangered species.

Major palm oil consumers such as Unilever (UNc.AS) , Nestle and Burger King stopped buying from SMART because of environmental concerns.
