Converting India’s Waste to Paper

Image
  Every year much rice straw is burnt in the fields causing much pollution in Northern India. However rice straw can be put to good use for many products, one of then being paper. A preliminary estimate by this author suggests that a mix of half and half rice straw and Bagasse, the residue left after crushing sugarcane to extract juice can produce good quality paper for printing and writing as also for boxes and newspaper. For every ton of sugarcane crushed approximately 30% tonnes of wet bagasse is produced. Adding 10% cotton fiber to the mix will yield high quality printing and document paper whereas adding 10% polyester fiber could yield quality paper for carry bags that may be used to replace plastic bags in current use. Further research shall help verify or refine the recommendations of this brief note. The State and Central Government of India can aid this effort in the following ways: Providing research funding to universities and

Three Effects of Deforestation on Climate Change

Image
Widespread deforestation has taken place on the planet over the last century due to human activity. While this deforestation affects the planet and all life that dwells upon it in numerous ways, this note mentions three effects on climate change that includes climate extremes 1. Atmospheric Turbulence The greater the atmospheric turbulence, greater are the chances of unexpected climatic phenomenon i.e. climate extremes. Winds move over the surface of earth in what scientists call as atmospheric boundary layers. It is well known phenomenon in turbulence science that turbulence in such boundary layers is damped when roughness exists on the surface. Forests with tall trees are one such roughness. Therefore the fewer the forests on land the greater the atmospheric turbulence and greater the chances of climate extremes. 2. Evaporation from Trees Evaporation from tree leaves absorbs the sun’s heat that falls on the planet. It is for this reason, during day ho

Solution to Water Crisis - Jaipur Case Study

https://en.wikipedia.org/wiki/Bisalpur_Dam#/media/File:Bisalpur_Dam.jpg    A tremendous increase of human population has taken place over the last century leading to a water crisis in both urban and rural habitations. The present note addresses this issue. A special reference is made to Jaipur city in Northwestern India but much of the note has value for cities elsewhere too. We shall begin with some essential fundamentals about water and then suggest immediate short-term and long-term solutions to the water crisis. Fundamentals of Water Use Along with light and air, water is the basis for life. Poor water quality and inadequate availability of water severely compromises quality of life and living. Therefore, it must be the top most priority for any society and its government. There is no shortage of water on the planet for all life that dwells on it. What may however lack is its proper management and distribution. Those wh
