Information on recycling and utilization of waste computers

Recycling and utilization of used computers 1, Japan's commonly used computers are desktop and handheld two categories, the annual production of 12 million units, the annual generation of waste computers about 80,000t, combined with desktop 4.67 million units, or handheld 26.7 million units. According to the user is divided into office use accounted for 85%, home use accounted for 15%. Office used computers have 1 / 3 into the old goods market, the household part of 1 / 7 into the old goods market, the total number of about 50% to the waste disposal industry for easy recycling of useful recovery after the rest of the hand over to the landfill, the household part of the large part thrown into the large pieces of garbage for landfill disposal.

2, in the initial trial run in the process, did the following:

(1) began to build a new type of regeneration workshop, such as TEPCO environmental engineering companies in Tokyo to build the first computer and then first hard disk data erased and cleaned, and then replace the basic software for sale, the price of a new product for the 1/4, if the software to change the type of the sale price increases, very popular with users. With the company's cooperation with Chinese Taiwan computer manufacturers in Japan legal person Moytak has a workshop in Shanghai, the recycling of used computers sent to Shanghai regeneration after re-importation is still competitive.

(2) In order to adapt to the needs of computer regeneration, YEC successfully developed a small device that can erase the data of two hard disks at the same time, which is easy to apply to the general public, and is priced at 149,000 yen per unit, with 400 units sold annually.

(3) Manufacturers from the design of the improvement, in order to improve the utilization rate of regeneration, such as Sharp memory alloys for the manufacture of screw tether, favorable decomposition; NEC changed to reusable plastic, the utilization rate of 90%.

(4) by the Electronics and Information Technology Industry Association is responsible for the various charges proposed and seek the views of all parties after the final program is: desktop each unit charged 4,500 to 5,500 yen, handheld each unit charged 1,000 to 1,500 yen. Acceptance of home appliances after the abolition of charges caused by illegal abandonment, will be changed to the purchase of new prices in the purchase of a new way before the levy, but currently still need to pay the fee to a certain stage of the waste are converted to the purchase of a new fee.

3, the existing problems:

(1) the parties to the charge is still controversial, such as users advocate the way before the levy, but manufacturers believe that the sale price is increased on the decline of the market is not favorable, still want to take the way after the levy.

(2) If the disposal fee cannot be lowered, there is little point in recycling. For example, desktop computers are disposed of as garbage in Tokyo at ￥6,500/unit, which is still beneficial; handhelds are not economically viable because of their low recycling value.

(3) the adoption of the former levy, after the levy of two-track charging method, will promote the old goods market and the rental market is booming. Users as old goods sold and purchased can be exempted from paying fees, and according to statistics, the average life of old goods & lt; 2 years, does not affect the use.
