Introduction
“Clean technology is also referred to as cleantech, green technology, and
greentech. It defines a set of technologies that either reduce or optimize
the use of natural resources, pollution control, resource reduction and
management, end of life strategy, waste reduction, energy efficiency,
carbon mitigation and profitability.”
(Source: Azocleantech
Or
"The continuous application of an integrated preventive environmental
strategy applied to processes, products, and services to increase overall
efficiency and reduce risks to humans and the environment."
(United Nations Environment Programme)
The clean Tech Revolution
Objectives of Clean technology
The objectives of clean technology of production are as follows:
Sustainable energy and energy optimization to reduce dependence on
fossil fuels
To reduce levels of polluting emission and waste generation thereby
protecting or improving the environmental quality.
To use raw materials and energy more efficiently.
To encourage utilization of residues, recyclable waste and local materials
as raw materials for conversion processes.
To provide local employment.
To enhance the quality of life.

Breakthroughs
1. Algae Biofuels

2. Zinc-Air Batteries
• With world zinc resources being 100 times more plentiful
than lithium ion, a move to zinc-air batteries has the
potential to make laptops more portable, electric vehicles
more affordable and hearing aids more reliable.
• Zinc is recyclable, relatively cheap and has a high energy
density. Currently used in non-rechargeable form in
hearing aids, zinc batteries are expected to be launched in
a rechargeable, longer-lasting version in a few years, with
an extension of use to computers and cars later.
3. Organic solar cells
4. Marine Energy

Cost-effective Desalination
Processes
Carbon capture and storage
 Carbon capture and storage (CCS) is capable of reducing carbon
emissions from gas and coal power plants, cement producers
and other large emitters by up to 90 per cent.
 Confusion over funding has made the realisation of plans lag
behind the science.
 More than 200 UK scientists at 36 universities are currently
involved in CCS research.
 The International Energy Agency predicts a need for more than
3,000 CCS systems worldwide by 2050 if temperatures are not to
rise by more than 2 degrees .
Solar Power
Precision Agriculture
• Clean-tech solutions for
agriculture help conserve water
and reduce the use of pesticides
and herbicides by targeting
applications only where they are
needed.
Electric Vehicles
•
(EVs) and charging systems. With motor vehicles
being the largest producers of greenhouse
gases worldwide, electric vehicles and EV
charging stations are among the fastest growing
forms of cleantech.
Sustainable Development Goals
Sustainable Development Goals
Goal 6: "Ensure availability and sustainable management of water and sanitation for all
Goal 7: "Ensure access to affordable, reliable, sustainable and modern energy for all"
Goal 11: "Make cities and human settlements inclusive, safe, resilient and sustainable"
Goal 13: "Take urgent action to combat climate change and its impacts”
Paris Agreement
