There are three different channels in the Recycling plant, namely Brown, Green and Clear, which represent the colors of glass. After recycled in the furnace, glass products are melted=forged into recycled liquid glass. Mixed with new liquid glass, the compound is finally moulded into solid glass, which, afterwards, will be sent to various customer supermarkets for selling. Thus, the glass will go to the customers for different purposes.Through a brief introduction of the circle of glass recycling, we come to realize that recycling plays a vital role inenvironmental protection and ecological preservation.The diagram below describes how to recycle organic waste to produce compost(fertilizer).1. The flow chart illustrates the recycling process of organic waste toproduce fertilizer.As is clearly shown in the picture, the first step is to find a plastic container of two cubic metres and stab several holes on its body so that air could fill in. Secondly, a 15cm thick layer of food is placed at the bottom of the container and grass is put just above the layer for the same height with some news paper covered on the very top. After that, some nitrogen and water are added into the container, and the water should only be hot. Finally, the container is sealed up and the external heat would help the formation of the compost. After six months, when the fertilizer is ready, all we have to do is to pour it into garden soil to nourish plants and flowers.Generally speaking, making garden fertilizer in this way is easy to operate but it costs much time.2. The flow chart shows the whole process of producing fertilizer by recycling organic waste.Firstly, a two cubic metres plastic container is prepared, with some air holes on its body. Secondly, some organic waste is put into the plastic container. The organic waste includes news paper, grass and food. The right order of adding them is putting food in the bottom 15cm of the container and grass in the middle 15cm upon food. News paper is on the very top. Then nitrogen and water are added into the container. What should be noticed isthat water can only be hot water. The next step is to seal up and heat the container. After six months, compost is produced. So we can use them to fertilize the garden.As can be seen from the picture, it is usually simple to change organic waste into fertilizer used to water flowers and trees in the garden.3. The information provided in the diagram is about how to use organic waste to produce compost in the following several simple stages.The first stage is to prepare a plastic container, two cubic metres in volume, with some ventilation holes on the side.Then organic waste such as leaves, pieces of paper and residues can be placed into the container so that three layers (each 15 cm) can be formed in the bottom---news paper, grass and food respectively from up to down. The next important step is to add nitrogen into it and then pour hot water only in to mix together. What is remembered to do next is that the container needs to be sealed and heated. As a result, the vapor can be emitted through the holes located on its body. After that it takes roughly six months to convert into composts and then they are ready for fertilizing plants and flowers in the garden.。
