As you can see from all the previous topic that garbage can cause a lot of problem but we still have some solution to make garbage be a useful thing.
But Firstly, let talk about how to make waste become less useless thing by 5R
But Firstly, let talk about how to make waste become less useless thing by 5R
R1:Reduce
R1:Reduce
is a fresh, unnecessary resource use. Or reduce the wasteful packaging products especially glue, energy consumption, resources. Such as natural gas, coal and ore, etc. By choosing to use sparingly. Such as turning off the fire and starving every time when not in use. Or travel not close to walking, riding a bicycle, etc. With this method, we will be able to conserve energy resources for a longer time. And conserve the environment to live longer
R2:Reuse
R2:Reuse
is make the most of the resources. By bringing the machine to use the legs Such as inserting the original dig That is still of good quality The prospect of going to Bree jack instead. Water to waste or use of paper both in front and after, bringing a glass of water to eat, or to make various utensils, etc. This principle will it helps to reduce cots while also helping to protect the environment effectively.
R3:Recycle
R3:Recycle
is the used resource. Come to transform and recycle to reuse By going through the production process again or curing cycles, for example paper made a paper box. Break through a can of soft drinks to make artificial tea Reusing glass or plastic into bottles and so on. This will reduce
R4:Repair
R4:Repair
is repair something to be able to use for example saw a torn shirt, computer repair etc.
R5:Reject
R5:Reject
Reject: is don't use or avoid object that cause the destruction of resources or damage the environment
Waste to energy
Waste to energy
Energy from waste is clean energy, potent energy, and has a high calorific value. And also doesn't affect the environment as well power generation has several methods are dependent on the type of waste, such as removing the quality-treated dry waste to high values and incineration on the grid. And when the doubt after heat, the heat was thrown to boil the water in the pot until it turned into steam. Which the steam will cause the turbine of the generator to burn until the creation of energy or another way is to bring organic waste or food scraps to be fermented to form bio-gas and then use it to generate electricity, or by using vacuum aspiration from landfills.
There are two part of The technology to generate energy from waste
1.Technology to produce energy from Raya, the process of changing life
2.Technology produces energy from waste by thermal chemical processes
The process of generating electricity in a mass-burn waste-to-energy has seven stages:
Waste is dumped from garbage trucks into a large pit.
A giant claw on a crane grabs waste and dumps it in a combustion chamber.
The waste (fuel) is burned, releasing heat.
The heat turns water into steam in a boiler.
The high-pressure steam turns the blades of a turbine generator to produce electricity.
An air pollution control system removes pollutants from the combustion gas before it is released through a smokestack.
Ash is collected from the boiler and the air pollution control system.
Global developments
Global developments
During the 2001–2007 period, the waste-to-energy capacity increased by about four million metric tons per year.
Japan and China each built several plants based on direct smelting or on fluidized bed combustion of solid waste. In China, there are about 434 waste-to-energy plants in early 2016. Japan is the largest user in thermal treatment of municipal solid waste in the world, with 40 million tons.
Some of the newest plants use stoker technology and others use advanced oxygen enrichment technology. Several treatment plants exist worldwide using relatively novel processes such as direct smelting, the Ebara fluidization process, and the Thermoselect JFE gasification and melting technology process.
As of June 2014, Indonesia had a total of 93.5 MW installed capacity of waste-to-energy, with a pipeline of projects in different preparation phases together amounting to another 373MW of capacity.
Nowadays, garbage pollution is serious, people began to carry out conservation actions, find ways to improve, hoping to reduce the nightmare of garbage pollution, they use garbage and recycled materials to make products, to achieve environmental protection purposes, although only a small change, but also to protect the earth to open a new way.
