Ceramic products are durable and have high ornamental value but are easily broken. Ceramic shards are difficult to decompose even after they have been weathered underground for thousands of years, and become environmentally polluting.
Nowadays, home decoration is not affixed with shiny ceramic products. The damage rate of these ceramic products during transportation and sales is between 2% and 6%, and there is also a lot of wear during decoration. There are also a large number of scraps that are cut off and cannot be reused. They all become rubbish, and the quantity is huge. In the ceramic production base, ceramic fragments pile up. According to reports, there are about 5% to 26% of waste products in the ceramic production process.
The composition of ceramic products contains a considerable amount of salt compounds such as lead, antimony, and cadmium, especially in its multicolored coating. The content of toxic heavy metal elements is very high, and they are buried in the soil in the role of acidic microorganisms. Underneath, toxic elements such as lead can be dissolved out, permeate the soil, destroy the quality of groundwater, and endanger the growth of crops and human health.
Fujian Dehua is an important ceramic production base in the south of China. Engineers and technicians have researched and developed ceramic regeneration technology and effectively solved ceramic pollution.
They crushed ceramic fragments and waste products into powder, then added a certain proportion of ceramic clay, processed and then burned to reproduce ceramic products. This ceramic regeneration process technology has low energy consumption, small modification rate, and good regularity. Its raw material cost and firing cost are reduced by 30% to 50%, respectively, while the daily value of recycled ceramic products remains the same and has been sold well at home and abroad.
Recently, an environmentally friendly ceramic product called Green Lithium Ceramics has been born, opening another passage for the treatment of broken porcelain. This kind of green lithium ceramic adopts the method of low-temperature firing. After the product is broken, it will be weathered and reduced under natural conditions, return to the soil, and there will be almost no pollution to the environment.
