Chemical Substitution in the Nepal Carpet Industry

[call-out: "the economic opportunity is significant, the market is responsive, and there are good indicators that the concept [of using Nepali-grown vegetable dyes] is technically feasible. And success would mean that industrial ecology is real enough to walk on"]Despite these resources, Nepal faces significant challenges in substituting locally-grown vegetable dyes for imported synthetics. Research is needed on the types of dye plants that would grow best in Nepal’s varied climatic conditions. If sufficient quantities can be produced, extensive quality control will need to be instituted to satisfy foreign buyers who want large lots of identical carpets. Although vegetable dyes are free of heavy metals, it is not clear that they produce less biological or chemical oxygen demand in wastewaters, or that they do not cause adverse health effects in some workers. Integrating Nepal’s carpet and agricultural industries would likely run into other challenges that are now unforeseen. Perhaps the greatest challenge will be getting the various organizations in Nepal that would be affected by the change to cooperate with each other. However, the economic opportunity is significant, the market is responsive, and there are good indicators that the concept is technically feasible. And success would mean that industrial ecology is real enough to walk on.
