| Efficient effluent treatment and usage of waste |
| Investments in efficient effluent treatment are rapidly becoming an across the board measure as sensitivity to toxic discharge issues increases, and this has been matched by innovative ideas for using treated effluent for irrigation, road washing, toilets, gardening, etc. The use of fly ash in building materials has long been advocated and now several industries are forging tie ups with brick manufacturers to convert this harmful air pollutant into a useful product. Even the transport of fly ash has received attention, with sealed pneumatic transport systems replacing water based slurry handling. |
