Straw changed furniture, new environmentally friendly, zero formaldehyde, non-polluting materials

You must know solid wood furniture, sheet furniture, but do you know that the straw that has been abandoned in the field after harvesting can also become the raw material for building furniture? Moreover, this is a truly environmentally friendly, zero formaldehyde, non-polluting furniture material.

The disposal of straw has always been a "difficult situation." The management department prohibits straw burning because it pollutes the air and there are fire hazards; but it has been repeatedly banned. The reason: in the absence of a more valuable "outlet", burning is still the most "lazy" way.

Nowadays, the continuous maturity of environmentally-friendly furniture technology has given the alternative value of straw, and solved an environmental problem with a creative and environmentally friendly way.

How does straw become furniture?

Entering the office building of Shanghai Yatelan Furniture Technology Co., Ltd. in Yangpu District, in the exhibition hall on the first floor, from the whole kitchen to the living room, bedroom, children's room and cloakroom, all the furniture looks like ordinary wood furniture. They are all made of straw boards.

“Straw board is a good material.” Yang Guang, general manager of Yatelan Furniture, told reporters that this is an environmentally friendly material that truly achieves zero formaldehyde. Because the straw is a crop, it is made into a board. The applicable glue is different from the general glue, but an ecological adhesive (MDI) without formaldehyde. This kind of ecological glue is very strong, so there is no need to worry that the furniture made of straw boards will not be reliable. Usually paint is another major source of formaldehyde in furniture, and attached to the surface of straw furniture is also a special water-based paint that does not contain formaldehyde.

In fact, the technology of straw boards has long been in Europe and the United States. However, there is no good straw recovery and decomposition foundation in China, and there are certain difficulties in straw board making. Fortunately, the government department has been promoting. In 2005 and 2006, under the force of the Municipal Science and Technology Commission and the Agriculture Committee, the British technology and straw board production equipment were introduced, and a factory was set up in Harbin. Straw board. However, at that time, the technology of using straw boards was not mature. Straw boards were used more on building slabs, and because of their relatively high cost, they were limited to government projects, and civil engineering was basically not used.

The equipment assembly line is not small, but the straw board is only used as a building template, and its market expansion is difficult to take. Until the 2010 Shanghai World Expo, the conditions for the straw board to become furniture were truly mature, and the market was more open. First, after many years of OEM, traditional furniture companies have no brand advantage, no pricing power, and various costs are getting higher and higher, it is difficult to go down. Enterprises are facing transformation and upgrading. Yang Guang told reporters that at the time of the company was two directions of transformation - intelligent and environmental protection, the Expo advocated environmental protection, and gave the company a good inspiration, so decided to move towards environmentally friendly furniture. Upgrade. Second, by 2010, the straw board's own technology is more mature, and you can try to make it into furniture. "After making the transformation decision, we also went to the European and American markets for inspection. Straw furniture is actually very popular." Yang Guang said.

As a result, Yateland furniture continued to invest, upgraded technology, and introduced straw boards to start making furniture. However, from the straw board to the finished furniture, it is not so simple. There are always difficulties in the process, and it is necessary to overcome them one by one. For example, after the straw board is made into furniture, it needs to be painted. At that time, it was encountered that the plant board is not compatible with the water-based paint, which causes the adhesion to be weak. There is a water-based paint that is specially matched with straw boards in foreign countries, but the import unit price must reach 700 yuan per square meter. Such a price is unacceptable in the market. Can only develop by yourself. “Ultimately, we were fortunate to have found several old professors, with their help, constantly debugging, and finally formulated a nano-scale water-based paint to solve the problem of painting the straw board at a relatively low cost. However, this The process is a heavy one." Yang Guang said.

After three years of continuous investment, by November 2013, the straw furniture products produced by Astralan were finalized and launched. During this period, it was really a test of the patience of a company. However, in Yang Guang’s view, since it is recognized that environmental protection is a trend, “it’s worth gambling.”

Turning waste into treasure

Straw furniture is on the market, how is the market accepted? From the point of view of price factors, the material cost of straw made into furniture is about 30% higher than that of ordinary plates. Therefore, the price of straw furniture is 25%-30% higher than that of ordinary plate furniture.

"At first, we still have some concerns, but from the feedback of straw furniture in the major stores, it is still very easy to be accepted by the market." Yang Guang explained that it is directed at straw furniture, zero formaldehyde, no pollution, consumers also Willing to pay more for this, "Today, our stores have been sold every day."

Moreover, the company also conducted a market research for consumers. The results show that the two types of consumers have greater demand for environmentally-friendly furniture. First, newly-married couples are prepared to have babies, so they pay more attention to the environmental protection of furniture; Retirees who are healthy and have a quality of life. In addition, many families also specialize in custom-made furniture for children's rooms.

Judging from these market feedbacks, Yang Guang is not worried about the future market. He is also optimistic about when the heavy investment in the past three years will be recovered. It is expected that the cost will be recovered by 2015.

Straw furniture, turning waste into treasure, gives straw a more valuable "out of the way". Compared with many traditional straw disposal methods, this is an industrial chain that is truly driven by the market. While the market pays for the environmental protection of furniture, it can also gradually solve the environmental pollution problems caused by straw burning in the past.

According to relevant information, China can generate more than 800 million tons of straw per year. In Shanghai, the total cultivated area is 244,000 hectares, and the annual straw output is about 1.6 million tons, mainly distributed in 9 districts and counties such as Chongming, Jinshan, Fengxian, Songjiang and Qingpu.

Although the management department has taken many measures to prohibit the open burning of straw and promote the comprehensive utilization of straw, the main utilization method is only to crush the field. This proportion is only six to seventy percent. Straw burning is still inevitable. Moreover, some experts have expressed disagreement with the use of straw smashing and returning to the field: after straw smashing and ploughing to the field, due to years of accumulation and difficulty in digestion, many fields have problems such as soil denaturation, increased pests and diseases, and reduced crop yield.

In addition, since the straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, it is also a roughage. Recycling straw as feed is also a way to use it. Shanghai Dingniu Feed Co., Ltd., a subsidiary of Shanghai Milk Group, regularly recycles straw from farmers for feed for dairy cows. However, the utilization rate of this method is only 50%. When the cows digest a part, there will be a lot of surplus, about 50%, and these surplus materials can only be crushed back to the field.

In the eyes of the industry, the milk company recycles straw, feeds the cows, and then the cows produce milk, which is made into finished milk. It is also a relatively complete industrial chain, but because of the low utilization rate, the added value is not High, its driving force from the market is far from enough.

In contrast, turning straw into a treasure into a piece of furniture is a true high value-added way of using straw.

High value utilization industrialization

Straw furniture has found a way for the high value-added utilization of straw. Atlanta furniture hopes to go further on this road.

According to reports, the company is currently negotiating cooperation with Guangming Group, hoping to sort the straw recovered by Guangming, and some of them are suitable for cattle to eat when the feed is used, and some straws that the cattle do not eat are used to make straw boards. This will achieve 100% high value-added utilization. With a stable supply of raw materials, Yatelan even hopes to introduce equipment, assembly lines, open a board factory in Chongming, Shanghai, or build or cooperate with others. In this way, the freight cost of more than 10,000 yuan per car is saved, the cost of the straw board and the cost of the straw furniture will be reduced, and the price will naturally be more close to the people. By then, the market share will gradually expand, and in turn, all links will benefit, and ultimately will promote the recycling of straw and reduce pollution.

Straw furniture is only one of the industrialization roads for the high value of straw utilization. With the promotion of government departments, there are more different explorations and attempts.

Not long ago, at the Yangtze River Delta Straw Comprehensive Utilization Industrialization Technology Matchmaking Meeting held in Shanghai, Shanghai Ai Nike Energy Saving Technology Co., Ltd. signed a cooperation agreement with Guangming Changjiang Modern Agriculture Co., Ltd. for the project of 30,000 tons of straw forming fuel project. ", used for clean burning. This is also a way to use straw at high values.

According to reports, the production of straw fuel is through crushing, dust removal, compression, shaping and other processes, the straw is compressed into a rod-shaped briquette fuel, small volume, high density, without any additives. Moreover, the combustion value per unit area of ​​the fuel is ten times higher than that of the general fuel, and the heat production and the resistance to refining are close to that of the medium coal, which can replace conventional energy such as coal and oil, and can be widely applied to biomass power generation, industrial production, Heating and heating for urban residents, and so on.

Chen Qing, secretary-general of the Shanghai Comprehensive Utilization Association, told reporters that the current development of industrialization of straw straw utilization in Shanghai has a general idea of ​​implementing scientific and technological innovation, synergy and cooperation, policy support, implementation of independent technology development and standard setting, and implementation of “who uses, Who benefits from the principle, promote key demonstration projects, eliminate straw burning, reduce the proportion of smashing and ploughing, and expand new areas of high value-added comprehensive utilization.

Specifically, the short-term goal of industrialization of high value of straw in Shanghai is: from 2014 to 2015, Shanghai will implement a batch of demonstration projects for straw biomass and flammable gas, and the annual utilization of straw for biomass renewable energy will be added. More than 30,000 tons; by 2015, the comprehensive utilization rate of farmland straw will reach over 90%. The medium and long-term goal is: from 2016 to 2018, it plans to build a key project with an annual output of 100,000 cubic meters of zero-formaldehyde straw board, supporting the production of 150,000 tons of straw feed, and comprehensively utilizing 500,000 tons of straw per year to build a high-efficiency crop straw. The new mode of comprehensive utilization of “cleaning and industrialization”; by 2018, the comprehensive utilization rate of crop straws will reach over 95%, of which the proportion of resource utilization will reach more than 50%.

The former chief engineer of the Municipal Economic and Information Technology Commission, Qinghai, also gave advice. Straw is a renewable resource. The comprehensive utilization of straw in Shanghai should be developed in the direction of large-scale and high-end. If a large part of the 1.6 million tons of straw produced in Shanghai each year is converted into “high value utilization”, then a new ecological industry with straw as raw material will be formed – “planting, aquaculture, agricultural and sideline products processing industry, straw industry four industries”. A combination of advanced stage eco-industry models.
