This is usually prepared by the shipper on forms issued by the carrier, serving as a document of title, a contract of carriage and a receipt for goods.
Any fuel that is derived from biomass, that is, plant or algae material or animal waste. Since such feedstock material can be replenished readily, biofuel is considered a source of renewable energy, unlike fossil fuels.
