. Identify the pollution source of the glass industry from the perspective of technology
Considering that environmental protection has become the main line logic affecting the supply and demand of industrial products in recent years, it is necessary to re-organize the pollution links in the glass production supply. In terms of upstream raw materials, the main sources of pollution are concentrated sand (dust) and soda ash. The degree of contamination in the production of float glass depends on the fuel used. In the deep processing of the middle reaches, large-scale automation enterprises have fewer pollution sources, and the main pollution is concentrated in small-scale deep processing enterprises with “small scattered pollution” which are extremely scattered.
The raw materials of float glass mainly include: fuel, soda ash, quartz and various chemical auxiliary materials. Among them, fuel and soda ash are the main costs of glass production, accounting for 42% and 25% respectively. Downstream of the glass terminal includes construction furniture, home appliances, automobiles, high-tech (display, photovoltaic) and other fields, accounting for 70%, 15%, 5% and 10% respectively. Real estate-related demand is about the trend of flat glass demand. About 60% of the flat glass flows into the terminal through deep processing, and 40% of the flat glass is sold directly to the terminal.
One of the results of the de-capacity: the off-season is not weak, the inventory growth is lower than the same period of the previous year
First of all, the inventory signal or the spring rebound in the spring of next year is impressive. As of the end of December, the national glass factory inventory days were 9.89 days, the lowest value since 2013. In the fourth quarter, the inventory showed an anti-seasonal increase, and the output and inventory signals seemed to be repeating the cement pattern in mid-2017.
Looking back at the changes in inventory and prices since 2012, we found that the inventory changes in the fourth quarter have a certain leading effect on the price rise and fall in the next year. From 2012 to 2017, the inventory in the fourth quarter of the previous year is inversely related to the annual average price of the next year. In the previous year, the inventory in the off-season increased, and the focus of the spot declined in the second year; if the stocks in the off-season fell in the previous year, it was often accompanied by the shift in the focus of the next year. As of mid-December data, the inventory of glass manufacturers nationwide fell by 0.09 days from the end of September. Inventory changes point to a shift in the price of the second year.
