Aspect Environmental Lining Ltd., Frankton, New Zealand, has seen a decline in demand for decorative pond liners and agricultural manure basins; at the same time, lining installations for heavy construction work and landfill cells remain a strong business. Possible reasons for the demand shifts: in tough economic times, decorative ponds may be expendable, and bio-gas from manure is a possible source of energy recovery, so is managed differently. Meanwhile, waste disposal continues at landfills, both of residential and commercial garbage and ash from waste incinerators. In the U.S., phased regulations requiring better stormwater control during, and runoff management after, construction projects could continue to increase business in that sector.
