Global warming is a serious problem that is addressed through green technologies. The document outlines 10 examples of green technologies: 1) emissions treatment to reduce greenhouse gases from industries, 2) waste-to-energy technologies that generate energy from waste, 3) advanced recycling and waste management technologies, 4) biofuels produced from waste, 5) wastewater treatment technologies, 6) solar energy systems, 7) wave and tidal energy technologies, 8) eco-friendly vehicles, 9) smart buildings that generate their own energy, and 10) vertical gardens and indoor farming that conserve resources. While green technology has advanced, more remains to be done to implement solutions to reduce pollution and waste globally.

• Global warming is a reality. It
is a growing problem upsetting
governments and society in
general and is endangering
health and the environment.
One of the ways to fight against
global warming is by means of
the so-called green
technologies. Engineers and
scientists around the world are
developing technological
solutions aimed at reducing
and eliminating everything that
causes global warming and,
therefore, climate change.
Please find below 10 examples
of green technology that are
environmentally-friendly and
widely used nowadays:

10 Examples of Green Technology

1. Emissions treatment
 The management of exhaust air
generated during industrial
production processes can
significantly reduce the
greenhouse effect. Methane and
carbon dioxide are substances that
harm the environment. Industries
such as the chemical sector, the
petrochemical sector or the
pharmaceutical sector must
eliminate their polluting emissions
so as not to cause serious
environmental damage. Check here
several technology solutions to
eliminate emissions.

2. Waste-to-Energy
 The generation of energy from
waste, also called Waste-to-Energy,
is technology that generates energy
from waste. This technology is
sometimes abbreviated as “W2E”
as well. There are several
technologies to achieve energy
from waste, for example
incineration or pyrolysis. Check
here several waste treatment
solutions that generate energy in
the form of steam, hot water or
electricity. Production plants can
use this extra energy for internal
processes, which has obvious
economic and environmental
advantages.

3. Recycling and waste management
 The increase in household and
industrial waste has been
disproportionate. Managing
solid waste is the commitment
of companies as well as
individuals. Outstanding
technologies such as smart
containers, automated food
waste tracking systems and
automated optical scanning
technologies can help sort
mixed plastics by separating
them from others.

4. Biofuels
 The valorization of
plastic waste to a value-
added product such a
biofuel is economically
feasible. It is a high
profitable business
indeed. The two products
that are generated at a
pyrolysis plant are fuel
oil and char, which are
versatile products, very
high in demand.

8. z 5. Wastewater treatment
 In this field, there are few
technological
developments, but the
existing ones are
important. Key
developments include
membrane filtration,
microbial fuel cells,
nanotechnology,
development of biological
treatments, etc. All these
processes are used to make
water drinkable or
significantly reduce the
presence of pollutants from
what is discharged into the
sea and rivers.

6. Solar energy
 Solar energy is energy from the
sun. This technology aims to
reduce dependence on energy from
hydrocarbons and fossil fuels and
promote greener solutions. Solar
energy systems are the renewable
energy systems that have been
worked on and researched the
most. Examples of solar energy
conversion technologies are high
vacuum tube for hot water,
polypropylene collector for hot
water, photovoltaic collector to
produce electricity and solar
streetlamps, among others.

7. Wave and tidal energy
 That is, energy from the oceans
waves and tides. The first wave
energy management plant was
built in Aguçadoura, Portugal, 8
kilometers away from the coast.
The plant has a capacity of 2.25
MW and is able to supply
electricity to up to 1500 homes.
The installation consists of steel
tubes floating on the ocean
surface, measuring 3.5 m in
diameter and 150 meters long,
called “Pelamis”. Those
components are semi submerged in
the sea and are responsible for
transforming the movement of the
waves into electrical energy.

 Known as ecological
vehicles, they do not emit
pollutants into the
atmosphere. They are called
“eco” because their use does
not negatively influence the
environment and contributes
to reducing the presence of
polluting gases in the
atmosphere. Those are mainly
carbon dioxide (CO2), carbon
monoxide (CO), nitrogen oxide
(NOx), unburned hydrocarbons
(HC) and compounds of lead
and Sulphur dioxide.

9. Smart buildings
 Smart buildings or self-
sufficient buildings are
those constructions that are
able to function by
themselves by generating
energy without the need of
an external
contribution. One way to
achieve greater production
with the same surface of
photovoltaic panels is to
incorporate intelligent solar
tracking systems, thus
obtaining an optimal use of
radiation.

10. Vertical gardens and farms
 The installation of vertical gardens in
buildings also helps save energy and
brings many benefits to the environment.
Vertical gardens don’t need watering
routines that involve unnecessary use of
water, and because they are installed
along a wall, they reduce the intense
hearing pollution that comes from the
outside and even that one that you can
generate. Moreover, it helps isolate the
high temperatures that are presented by
climate change, resulting in significant
savings in energy, heating and air
conditioning. If we extrapolate this
technology to farms, we can save a lot of
water and take care of the fertile
soil. Today, there are vertical farms of
up to 100 hectares.

14. z
 Those were 10 examples of green
technology very much in demand
nowadays. There are many
technological advances for industries
and households nowadays, but still
much remains to be done in the field
of implementing measures to reduce
pollution and waste worldwide.
