Make the most of it! Waste and in-plant recycling



Reuse of waste resources:




The waste management of Lianjia Optoelectronics adheres to the principle of recycling. In order to avoid waste that cannot be effectively treated under environmental impact, through source classification, process waste reduction and recycling and other operations, the amount of waste in incineration and landfill is reduced. In terms of external treatment, reuse is the priority, followed by incineration and burial.




Through the inspection and evaluation of waste recycling in the factory, and the development of relevant units and visits to processing manufacturers, a reduction plan is proposed:


project Output ( tons / month ) current handling Anticipated treatment Expected benefits
carrier tape 3~4 incineration Reuse into plastic raw materials • Annual reduction of 74~98 tons of CO 2 e emissions
• The effect of recycled plastic raw materials is counted by recycling manufacturers
Static bag 0.5 Reuse sustain reuse into fuel rods Fuel rods provide generators to burn to generate electricity, with about one-third the carbon footprint of burning coal.
Bubble bag 0.364 Resource recycling
( small bubble bag ) 		maintain resource recovery The amount of resource recovery in 2021 is about 21,840 yuan
Incineration
( big bubble bag ) 		sustain incineration volume of the bubble bag reduces the frequency of removals and reduces CO 2 e emissions by 136 kg per year
roll _ 0.5 Recycle maintain resource recovery • The material staff collects the reusable material rolls every day , which is expected to save about 498,300 yuan / year
• 2. The amount recovered in 2021 is 33,200 yuan


Carrier waste recycling




process produces a large amount of carrier waste . After inspection, communication and evaluation, a recycling manufacturer is found to convert the carrier waste from incineration plants to recycling and recycling. The benefits are as follows:
  1. Reduction of 74~98 tons of CO 2 e emissions per year (emissions = 3~4 tons per month * 12/ year * emission coefficient 2.06 = 74~98tons )
  2. The effect of recycled plastic raw materials is counted by recycling manufacturers


Process of carrier tape waste :






Reduced frequency of removal of large bubble bags




After inspection, communication and evaluation, the manufacturing department assists in cutting and reducing the volume of the air bubble bag waste generated by the raw material packaging, so as to achieve the purpose of reducing the number of clearing and transportation. The benefits are as follows:
  1. Frequency of cleaning and transportation: The frequency of cleaning and transportation has been reduced from once a month to once every two months , and the waste storage space in the factory has been increased.
  2. CO 2 Emissions: By reducing CO 2 from transportation , approximately 136 kg of CO 2 e emissions can be reduced per year
  3. Emissions = Hsinchu Incineration Plant one-way distance 17.3km*6 times / year*emission coefficient 0.00131=0.1359ton

Roll waste reuse:




The material rolls used in the company's internal distribution will be reused many times after screening:
The average daily use is about 150~200 (the number of daily use is irregular, it depends on the work order , some are used for the first time, some are used repeatedly, about 100 small, about 50 medium, about 50 large)




Estimated savings from reuse:


If the reel is purchased by yourself, the approximate cost of 3 sizes is: small 4.1 yuan , medium 5.2 yuan, and large 29.9 yuan. The benefits of the reel :
  1. Up to about: 4.1*100+5.2*50+29.9*50=2,165 yuan per day, 47,630 yuan per month , 571,560 yuan per year
  2. Minimum: 4.1*76+5.2*37+29.9*37=1,610 yuan per day, 35,420 yuan per month , 425,040 yuan per year
  3. Average: daily (2,165+1,610)/2=1888 yuan, 41,525 yuan per month , 498,300 yuan per year


Recycling process of reel waste:


  1. The manufacturing department receives materials from the material department
  2. Manufacturing process use
  3. Empty reel collection in manufacturing
  4. Empty material from the manufacturing department to the material department
  5. Material Department Screens Empty Reels
  6. Material department prepares materials to manufacturing department
