The lack of paper making raw materials is a common problem, the use of seasonal growth plants or wild trees etc for the paper pulp is an effective solution.However, using this material pulping will produce a lot of black liquor containing inorganic compounds, how can get more fiber pulp, low investment to processing black liquor which can let it reach the water recycling or reach the discharge standard of environmental protection, it has been a worldwide problem all the time.

Han Xiaoping, chief information officer of China Energy Network, said that at present, Zhejiang province has already implemented ladder electricity prices with three gradients. The difference between the first gradient and the second gradient is 2 cents, and the difference between the second gradient and the third gradient is 1 cent. . It is expected that the Beijing ladder electricity price will refer to the Zhejiang Province plan, with the first gradient electricity price unchanged, and the second and third gradients each increasing the electricity price on the basis of certain electricity consumption limits. However, there is no accurate information on the current gradient power quotas and prices.
As early as October 2010, the China Development and Reform Commission proposed to implement a residential electricity price ladder. At that time, the public was most concerned about whether the price of the first ladder would be lower than the existing electricity price. However, due to the failure to implement the ladder electricity price, this problem will be solved. The. In this regard, Han Xiaoping said that the current price ladder program is expected to be the first gradient power price is unlikely. However, he also said that after the launch of the price ladder, it would be beneficial to adjust the structure of residents' electricity prices. The electricity prices of the high ladder will inevitably make residents choose to save electricity.
Galaxy Securities electric power industry analyst Zou Xuyuan said in a telephone interview with reporters that the ladder price will be gradually promoted nationwide, with the main manufacturers of smart meters such relays (000400. SZ), Samsung Electric (601567. SH) And smart substation equipment manufacturers Guodian NARI (600406. SH), State Power South (600268. SH) will benefit from the introduction of this policy. 
Beijing will push up the price of ladder electricity smart meters
It is reported that Beijing has already purchased 1 million smart meters for the implementation of ladder electricity prices, and will continue to purchase smart meters during the implementation of the later step price. Recently, the Beijing ladder price will be implemented.
