The new coal-fired power stations are environmentally acceptable and efficient, producing enormous outputs of electricity, shaming wind farms.

These methods are not environmentally acceptable because of the leachability of cyanides and fluorides.

Another important advantage of biocatalysts are that they are environmentally acceptable, being completely degraded in the environment.

Hydraulic hammers are more environmentally acceptable than the older, less efficient hammers as they generate less noise and pollutants.

The broad management options for re-use are direct injection, environmentally acceptable direct-use of untreated water, or treatment to a government-issued standard before disposal or supply to users.
