InIndustrialization is increasing every day in India. The environment is polluting because of improper treated or untreated solid and liquid wastes discharged from tanneries. Tanneries are one of the most polluting industries mainly causing chromium and chloroorganics’ pollution in the environment. Such toxic wastewater is polluting soil and groundwater that pose a serious health threat to plants, human and animals.
Biomedical waste (BMW) are potential hazardous waste materials consisting of solids, liquids, sharps, and laboratory wastes which are hazardous to the health of humans as well as other living organisms. So, it becomes one of the greatest challenges of modern era to subdue the catastrophic effects of biomedical waste. The activities that are usually performed as part of health care waste management involve segregation, storage, collection, transportation and disposal of biomedical waste.
Sugar distilleries are one of the most polluting industrial sectors generating huge quantity of wastewater that cause a severe ecological anxiety. Distillery spentwash is described as dark brown color, acidic pH, high temperature, low dissolved oxygen, high biochemical oxygen demand and chemical oxygen demand properties. Spentwash disposal into the ecosystem before treatment is harmful and causes terrestrial and aquatic pollution. The dark color of distillery effluent leads to decline of sunlight dispersion, decreased photosynthesis process in water ecosystem, therefore becomes injurious to waterbodies. It also leads to reduction in terrestrial basic pH and hindrance the seed germination. Different physical, chemical, and biological techniques have been studied for distillery effluent treatment.
Electronic waste (E-waste) has created a new threat to global environment. The daily life style to advances in science and technology is based on electronics and electrical equipment. In daily use these waste are generated from local to global level and from domestic to industrial and scientific activities. The economic growth is also important factors to generate advances in the electrical field and also concern to waste generation. In the residential area the common E-wastes are Electrical Bulb, tube light, mobile phone, grinders, televisions and air conditioners, fan, motor pump etc. Similarly, in commercial area all these electrical equipments are continuous utilized with their advancement. Whereas, Industrial area the advanced electrical equipments are used for production of products and to increase the efficiency of the production.
