In terms of worldwide production and usage, CCA is recognised
as the most effective wood preservative chemical currently
available for combating fungal decay and insect infestation in
timber. In a number of developed countries, environmental
and health related concerns have been raised and restrictions
on its use in situations involving direct human contact have
been imposed.

This has stimulated the search for suitably effective alternatives
and Dolphin Bay is monitoring and evaluating these developments
closely. Manufacturing and marketing alliances have been
forged, and are continuously being pursued, with both the
suppliers of raw materials and the manufactures of wood
preservative chemicals to ensure that Dolphin Bay remains
at the cutting edge of environmental and technological advances
within the industry.

The production and use of wood preservative chemicals is
highly regulated and closely monitored by government at the
national and local level. Environmental Impact Assessments
and licensing agreements are prerequisites for the plants
producing and using the regulated products.
