摘要:

THE disciplines of the market and basic economics will ensure that there will be no future shortage of scrap, according to Stephen Wulff of US-based scrap group David J. Joseph Co. Speaking at MBM's recent Electric Furnace Raw Materials Conference in Singapore, Wulff acknowledged that there has been unprecedented growth in demand for purchased scrap. Indeed, in the USA there has been a 10 percent increase in the use of scrap per ton of steel made. However, he assured delegates that the basic economic fundamentals of supply and demand will work their course, and that where there is a demand the market will develop to fulfil it. In turn, the costs incurred in production of the necessary supply will invariably regulate this demand, ensuring that there will be no shortage of scrap. He advised consumers to source their scrap from a number of areas, thus providing themselves with a flexibility which will enable access to a variety of sources, and to the best scrap or scrap substitutes in the market.
