Find one example of a product where the largest or most detrimental environmental impact persumably derived from each of the following:
1. Raw Material Acquisition
2. Production
3. Consumption
4. Disposal
Paper production in paper mill is the best example for given problems.
1) Raw material acuisition:-
For making papers in paper mill lots of tress have to cut and transported to paper mill. Acuisition of such fresh fibers of plant generate the fossile fuel based carbon dioxide due to transportation of fresh fibres. Very tremendous amount of such fibres can cause polution of near water sources and soil pollution. Lots of cutting tress can adversly impact on biodiversity, water resources etc.
2) Production:-
Production of anything causes pollution due to the use of different types of machines. And machines requires some input energy like fossile fuel, electricity etc which causes air pollution. In paper production waste water is tremendously produces which cannot be 100% treated and this residual waste water causes water pollution and impact on biodiversity.
3) Consumption:-
Consumption and need of papers is the main cause of production of papers and so production is main cause of pollution as given in above topic. In day to day to life lots of papers are required for toilet paper, tissue paper, bills, notebooks, books ect which is either used of teared or wasted and such wasted papers can cause disposal problem and cause pollution to water and soil etc.
4) Disposal:-
Products made in paper mill is recycled or disposed off as solid waste. This solid waste is either composted or burnerd and due to the burning harmful gases like carbon dioxide are generated. And these gases adversly affect to the environment. Because carbon dioxide is most important green house gases.
