A successful EERFERB process will be achieved by utilizing not
only advanced technologies and products, but also state-of-theart methods of appraisal and construction. However, China’s
ability to successfully implement EERFERB lags behind that of
developed countries. Only a few small-scale demonstration
projects have been undertaken using some simple technologies
and products. In several climatic districts in China, there are no
retrofit technologies adapted to local conditions that are economically viable. Also, there is no general EERFERB standard applicable
to all situations.
