Waste Plastics Recycling and Utilization--the Great Way to Money (2)

Application range of recycled plastic particles

After the waste plastics are processed into granules, they still have good comprehensive material properties and can meet the technical requirements of blown film, drawing, drawing, injection molding and extrusion profiles, and are widely used in the production of plastic products.

In daily life, recycled particles can be used to make various plastic bags, buckets, pots, toys, furniture, stationery and other life appliances and various plastic products. In the apparel industry, it can be used to make clothing, ties, buttons, and zippers. In terms of building materials, it can be used to manufacture various building components, construction tools, plastic doors and windows, plaster buckets. In agriculture, it can be used to make agricultural films, pumping pipes, agricultural machinery, fertilizer bags, and cement bags. In the mechanical industry, recycled particles can be used to manufacture machine parts, various types of bearings, gears, cams, different wheels, seal rings, various blades, and various pump impellers after being specially formulated. In the chemical industry, it can be used for reactors, pipes, containers, pumps, valves, etc., and is used in chemical production sites where corrosion and wear are solved. In addition, recycled particles are also widely used in the electrical and telecommunications industries.

Market prospect of recycled plastic particles

Recycled plastic pellets have a very wide market and plastics companies have a large demand. To fully understand why recycled particles are particularly favored by plastics manufacturers, let's start with a cost account:

A medium-sized agricultural film factory requires more than 1,000 tons of high-pressure polyethylene (LDPE) per year. At present, the average price of LDPE in the plastics market across the country is 7,000 yuan / ton, the average price of LDPE recycled particles is 3,800 yuan / ton, a difference of 3,200 yuan per ton. In other words, if a medium-sized agricultural film factory purchases recycled plastic pellets in half, the raw material cost alone can save 1.6 million yuan in one year. This is undoubtedly a huge wealth!

According to official statistics, in 1999, China produced 4.346 million tons of polyethylene, which could only meet 46.4% of the domestic market demand. At present, China's ethylene equivalent demand will increase by 8.5%, and by 2005, ethylene equivalent demand will be 15 million tons. For this reason, the country will spend a lot of foreign exchange importing ethylene raw materials or crude oil each year to meet the huge gap in domestic ethylene demand. Therefore, recycling of waste plastics can also save the country a lot of foreign exchange.

A medium-sized plastic woven bag factory consumes more than 2,000 tons of polypropylene regenerated pellets each year, even if individual small plants consume hundreds of tons per year; a medium-sized shoe factory needs 2000 tons of polyvinyl chloride (PVC) recycled pellets annually... Plastics The huge demand for recycled pellets by product companies has provided ample market space for companies and individuals who have intentionally established waste plastics recycling pellet factories. Therefore, recycled plastic particles do not sell at all.

Factory profit analysis

In order to help you objectively understand the cost and profit situation, here we use a production line with a monthly output of 30 tons to process high-pressure polyethylene waste as an example. We use relatively conservative data and carefully calculate the actual profit of a regenerative plastic pellet plant. For investors' reference. The main basis: 1. Discarded plastics around the middle price of 1,800 yuan / ton. 2. Recycled granules sell at an intermediate price of 3,700 yuan/ton. 3. The rate of recycled plastic particles is 90%. 4. Water expenses and inconvenient training-calculated sporadic expenses are included in “other unpredictable expenses”.

First, the overall cost (ten thousand yuan):

1. Raw material cost: 1800 yuan x 30 tons yuan 90%
2. Electricity fee: The actual power consumption of processing a ton of grain is about 300 degrees x 1 yuan x 30 tons = 0.90 million yuan. Water fee: It takes about 10 tons of water to clean a ton of waste plastic and it can be recycled.

Due to the low cost, it is included in "other unpredictable expenses".

4; plant rental: 0.20 million / month.

5. Workers' wages: According to two shifts per day, each shift is calculated as: 6 x 800 yuan/month 0.248 million yuan.

6. Transportation costs: 100 yuan / ton x 30 million tons = 0.30 million yuan 7. Other unpredictable Feichuan: 0.20 yuan/month

The comprehensive cost of producing 30 tons of particles per month is: 80,800 yuan.

Second, the monthly sales revenue: 3,700 yuan / ton x 30 tons two 111,000 yuan

Third, the monthly profit: 111,000 - 80,800 = 30,200 yuan

IV. Investment recovery period: 1-2 months

V. Annual profit: According to the annual production of 10 months, the annual profit is about 300,000 yuan.

In summary, the establishment of a recycled plastic pellet plant is a good project with less investment, short payback period, quick return, and lucrative profits.

Factory conditions

Established a recycled plastic pellet plant, the scale of investment can be. You can start from a production line or purchase multiple sets of equipment at the same time. It is recommended that you determine the size of your production scale according to your actual conditions. Only when you are stable and steady can you win.

1. Plant requirements: Take a production line as an example, the plant is about 30 square meters, requiring water, electricity (must be power), about 30 square meters of material yard (waste plastic cleaning, classified sites). If more than one production line is installed at the same time, a crushing workshop, a granulation workshop, and a finished product warehouse should be set up to facilitate daily management and improve production efficiency.
2. Workers: A production line requires only 2-4 workers (two shifts). If scale production, the number of workers should be appropriately increased. Workers should have a degree of education above the primary school level. It is recommended that investors give priority to hiring laid-off workers because they all have certain skills and organizational discipline concepts. They are quick and easy to manage.
3. Plant cycle: only 5-7 days.
4. Liquidity: The production of a production line, liquidity should not be less than 5,000 yuan. Scale production should increase its liquidity appropriately.

Recycled particle process

Melting and recycling of waste plastics is a method of re-heating and pelletizing waste plastics. From the source of waste plastics, this method can be divided into two categories: First, the recycling of waste plastics from scraps of resin plants and processing plants. The second is the recycling of various plastic products mixed together after use. The former is called pure regeneration, while the latter is called composite regeneration.

Waste plastic color and modification technology

Washed waste plastics are pelletized prior to molding. After the waste plastics are used, they all produce different degrees of aging, and the auxiliaries contained also have different degrees of losses. Therefore, it is often necessary to add certain auxiliaries, such as plasticizers and stabilizers, before granulation. At the same time, since recycled plastics are often made up of many different colors of waste, it is generally necessary to add some dark coloring agents during the regeneration process.
