‘Shanghai Municipal Solid Waste Management Regulations’ will be implemented on July 1, 2019, and Shanghai Municipal Solid Waste Classification will enter the era of compulsory classification.

When people heard this new, there is a voice on the internet: Will garbage recycling do harm to our health?

Garbage classification,in addition to compulsory, but also need to let the public know what is recyclable garbage, why do we need to sort the garbage, where are all the recycled garbage going?

According to the report of Xinhua news agency on June 6,2019. Domestic garbage classification has been started in cities at prefecture level and above in chine since 2019. 46 key cities will set up domestic garbage classification processing system till 2020.

Actually as early as 2017, China has publicly released the ‘Implementation The Plan of Domestic Garbage Classification management’, which including the description for types of recyclable.

recyclable stuff:

1.       main varieties. Including: waste paper, waste plastic, waste metal, waste packaging, waste fabric, waste electrical and electronic equipment, waste glass, Plastic-Aluminum Composite Packaging, etc.

2.       Put in temporary storage: According to the quantity of recyclables produced, containers or temporary storage space are set up to realize separate classification and fixed-point delivery, and special personnel can be set up to sort and pack when necessary.

3.       Collection, transportation and disposal: The main body of recyclable products can be transported by itself, and can also collect and dispose of recyclable resources by door-to-door contact with enterprises of recycling and utilizing renewable resources.

Part one:

Plastic garbage is getting more and more serious and It’s urgent to recycle it.

Take plastic garbage as an example, in recent decades, the pollution of plastics on the earth has been steadily advancing, from urban and rural areas to plateau desert, to rivers and rivers.

In February 2019, researchers from Newcastle University, UK, and academics from two other institutions published an article in an open access journal of the Royal Society, revealing that they found synthetic fibers and microplastics in the intestines of marine organisms in several deeper areas of the ocean. One of these ocean areas is the Mariana Trench, the deepest known trench, which may mean that there is no longer a plastics-free zone in the ocean.

So it’s critical to boost Recycling and Utilization of Plastics to decrease the environment pollution.

There are many kinds of plastics, including PE (polyethylene, often used to make food fresh-keeping film, pipes), PP (polypropylene, often used to make toys, stationery), PVC (polyvinyl chloride, often used to make pipes, plates) and so on. We take familiar PET plastics as an example to understand how plastic waste will be treated after recycling.

PET plastic is a kind of material with excellent performance in daily life. It is commonly used as beverage bottles on supermarket shelves. Turn over the mineral water bottle in your hand and you will find a triangle with three arrows at the bottom representing the circle, with a number of 1 in the middle and three letters marked with the letters of PET on the outside of the triangle. If you have this sign, it means you are holding a PET bottle.

The Chinese name of PET is polyethylene terephthalate, which is a saturated thermoplastic polymer. Under certain temperature conditions, the plastic can be softened or melted into any shape, and the shape remains unchanged after cooling. This state can be repeated many times. The main uses of PET are to make polyester fibers, polyester films and polyester beverage bottles.

If the name of polyethylene terephthalate is unfamiliar, then the polyester fibers made of PET (commonly known as polyester) must not be unfamiliar to you. It is often found on the ingredient label of everybody's clothes. It's the largest variety of synthetic fibers. There's also a name for it. This kind of fiber has good wrinkle resistance and shape retention, and has high strength and elastic resilience. It is durable, wrinkle-resistant, non-ironing and non-sticky.

Part three:

What else can you do with PET bottles thrown away after drinking?

There are two main ways to recycle PET wastes：

One method is to recycle monomer terephthalic acid and ethylene glycol by degradation, or to add organic solvents and additives to produce floor coatings, adhesives and lubricants. For example, alkyd resin paint can be obtained by alcoholysis of recycled PET and condensation with dicarboxylic anhydride to a certain acid value, dilution, filtration and addition of appropriate catalyst. It has the characteristics of good adhesion, acid resistance, alkali resistance and waterproof, and can be used as ground coating.

Another method is to directly regenerate and plasticize the recycled PET or to prepare the products of modified recycled PET by blending modification. For example, recycled PET plastic bottles are reclaimed by cleaning, separating and drying. Containers, accessories, fibers, etc. that can be used to prepare non-food products.

When it comes to fibers, one might ask: PET raw materials can be spinned. Can recycled PET mineral water bottles be spinned again to make fibers?

Yuppp！Absolutely！！！

At the end of last century, the annual consumption of PET used in fibre industry was about 11.4 million tons, accounting for 70% of the total production of PET in the world. The recycled PET is finally spun into polyester yarn and woven into polyester fabric through separation, cleaning, crushing, drying, plasticizing, polyester strand, carding and other processes.

Clothing Containing 88.9% Polyester Fiber

In addition to the preparation of polyester fabric, recycled PET can also be used to produce non-woven fabric, which is a product using new spinning technology. At present, non-woven shopping bags are strongly advocated to replace disposable plastic bags to reduce the production of plastic waste. In fact, PET non-woven fabric is also a kind of plastic, so I hope you can recycle non-woven shopping bags. In addition, recycled PET can also be used to spin carpets. It can be seen that the recycling and utilization of PET is extensive.

The recycling of plastic bottles can effectively reduce solid waste in the environment, save energy and protect the environment. Garbage recycling is the basis of classified treatment and utilization of garbage. It is of great significance to recycle garbage well.
