Environmental technology is a concept to achieve certain goals. Where in its implementation refers to environmental factors. Currently, technological developments are increasingly rapid, starting in the fields of agriculture, large industry, and household scale industries. Improper use of technology can cause environmental damage. The existence of this technology aims to provide convenience and fulfillment of human needs.
environmentally friendly technology is a technology that in its manufacture and application uses environmentally friendly raw materials. An effective and efficient process that produces minimal waste can reduce and prevent pollution or environmental damage. Environmentally friendly technologies must meet regulatory requirements. In addition, it is efficient in the use of resources, be it water, energy, use of raw materials, and chemicals.
Examples of environmentally friendly technology
Environmentally friendly technologies have been applied in various fields, such as in the fields of energy and industry, the environment, and transportation.
Applications in the fields of energy and industry, as follows:
Biogas is a type of alternative fuel that has been used as fuel for household needs in various countries.
biogas is obtained from the fermentation process of organic matter by anaerobic bacteria (bacteria that live in an environment without oxygen). The bacteria convert organic matter into methane gas by 75 percent and other gases such as carbon dioxide, hydrogen, and hydrogen sulfide.
One of the true statements about biofuels is the technology of providing alternative energy by using natural resources and can be renewed. Biofuels are derived from organic materials, such as plants.There are two types of biofuels, in the form of ethanol and biodiesel. Ethanol is a type of alcohol that can be made by fermenting carbohydrates. While biodiesel is a natural fuel that is usually obtained from vegetable fats.
Solar cells are how to convert solar energy into electricity. When the sun passes through the solar panel, the light will produce electron emission in the panel components. Furthermore, the electro is connected to a certain system so that it produces electricity. The electricity is supplied and stored in the battery.
generator that relies on the potential and kinetic energy of water to produce electrical energy.
• Wind power plant
A wind power plant is a power plant that uses wind as an energy source to produce electrical energy. This plant can convert wind energy into electrical energy using wind turbines or windmills.
Applications in the environmental field, as follows:
Biopore is a cylindrical hole that is made vertically into the soil for water absorption. Where it aims to overcome puddles by increasing water absorption in the soil.
Phytoremediation is a bioremediation process using a variety of plants to remove, remove, and destroy contaminants in soil and groundwater.
Applications in the field of transportation, as follows:
• Hydrogen vehicle
A hydrogen vehicle is a vehicle that uses hydrogen gas as its fuel. Not only limited to cars, but can be used on planes. Basically, environmentally friendly vehicles do not use conventional fuels such as fuel oil which causes pollution.
• Electric car
An electric car is a vehicle that uses one or more electric motors as its driving force. There are three types of electric car vehicles that exist so far. Namely, electric cars powered by external charging stations, electric cars with stored electricity with initial power from wild sources. Then the electric car that uses an electric generator.
• Solar cars
Solar cars use solar energy as a power source to drive them. In order to be used in a stable way, it is usually equipped with an energy storage area.
Eco-friendly technology function:
1. Preserving nature from damage
2. Maintain a beneficial environment for maintaining health
3.Minimizing waste so as to prevent environmental pollution 4.Utilizing useless items into useful products for humans
5. Facilitate and fulfill human needs
