MARKING its silver jubilee on Sunday, the Salem Tree Club released a declaration that spells out eco-friendly solutions to day-to-day pollution. Pasumai Thayagam chairperson Sowmiya Anbumani received the first copy, which would be submitted to the government also. The declaration opens with a demand to ban tree cutting for fuel and other usage. Holding denudation of forests the prime reason for the rapid effects of global warming, it suggested new technologies for alternative fuels from natural waste and agricultural product waste. Biomass briquette made from a mixture of straw, tamarind shell, sugarcane waste, equivalent to coal in terms of utility, could be used as an alternative to firewood, it said.Erosion of top soil of fertile agricultural lands could be arrested by using bricks made of fly ash instead of red soil, it added. Granite chips could replace river sand as it is scientifically proven to be an eco-friendly substitute. The government should enact laws making this compulsory. Fifty per cent of the non-degradable plastics could be disposed off safely by using 15 to 20 per cent of the same in tar road laying. The Club would be able to provide technical know-how.
