They are therefore no substitute for, in particular, the withdrawal of specific high-risk materials.

Microwave treatment of organic waste tends to be small scale and is predominantly used to sterilise high-risk material.

The British press was scandalized, and the director worked only sporadically thereafter, and never again on the kind of high-risk material that fired him up.

I would also point out the importance of the compromise reached between the two largest political groups in terms of reducing the extent to which the entire chemical industry was to be obliged to replace high-risk materials regardless of the risks involved.

FDA has published two rules to protect animals and consumers against BSE by prohibiting the use of most mammalian protein in the manufacture of animals feeds given to ruminant animals and by removing high-risk materials from all animal feed.
