KUALA LUMPUR, Oct 8 (Reuters) - A top palm oil industry expert on Tuesday stated Indonesia's prepare for the prevalent usage of the palm-oil based B40 biodiesel from next year would be "catastrophic" for the market, as it would involve the additional use of 1.5 to 1.7 million metric heaps of the product.
