13、sis weight is a necessity for the resource recycling potential analysis of domestic waste. However, all we know about urban domestic waste at present is how much it has been collected and transported instead of being pro
14、duced, and for rural domestic waste, we lack both. Therefore, we have to estimate the production from the weight of collected and transported waste, and calculate the production of rural domestic waste accordin</p>
15、<p> 2.1 Annual production of urban domestic waste </p><p> According to the Ministry of Construction, urban domestic waste that was collected and transported in 654 cities of China amounted to 157,
16、000,000 tons in 2010. The production is supposed to be 25% higher, or, according to Zhang Li Jing’s conservative estimate, 30% higher. So the actual production of urban domestic waste in the 654 cities may be estimated b
17、etween 196,250,000 tons and 204,100,000 tons – 200,000,000 tons for convenience.</p><p> 2.2. Annual production of rural domestic waste </p><p> According to a nationwide survey on drinking wa
18、ter and environmental health in rural areas that was jointly organized by the National Patriotic Health Campaign Committee and the Ministry of Health from August 2006 to November 2007, domestic waste was a major part of
19、farmer household waste, the daily production of rural domestic waste was 0.86kg per person, and every year there was nearly 300,000,000 tons of domestic waste produced in China’s rural areas, of which 1/3 (about 100,000,
20、000 tons) was</p><p> 2.3. Total dry-basis weight of urban and rural domestic waste</p><p> The average water content of urban residential waste in Beijing is 50.19%. Estimated from a water co
21、ntent of 50%, the 200,000,000 tons of urban domestic waste produced in China includes about 100,000,000 tons of water, which means the total dry-basis weight is 100,000,000 tons. Calculated from a water content of 35.79%
22、 of rural domestic waste in Beijing, the 300,000,000 tons of rural domestic waste in China is the sum of 107,370,000 tons of water and about 200,000,000 tons of dry-basis waste. In</p><p> 2.4. Reference ph

24、 components in Table 1and Table 2, and that of rural domestic waste is based on the findings of Xie Dongming.</p><p> Table 1. Physical components of domestic waste in the eight urban districts of Beijing,

27、re estimated as follows. </p><p> 3.1. Food waste </p><p> Urban food waste. Urban household food waste are a quite large part of domestic waste (as shown in Table 1, food waste accounted for
28、66.22% of the domestic waste in the eight urban districts of Beijing in 2007). For convenience, we assume 60% of urban domestic waste is food waste in average, so there would be 120,000,000 tons of food waste in the 200,
29、000,000 tons of urban domestic waste. According to Li Zhenshan et al., the dry weight of food waste is 20-25%, so the annual total dry</p><p> According to Table 3, food waste accounts for 24.5
30、4% of the total rural domestic waste in China. Based on a rounded percentage of 25%, the total amount of rural food waste in China would be 75,000,000 tons, including 17,500,000 tons of dry-basis waste (dry-basis content
31、: 23%) which could produce 13,562,500 tons of organic fertilizers (17,500,000 x 1.55 = 27,515,000/2). </p><p> According to the above analysis and estimates, the theoretic potential amount of organic fertil
32、izers from food waste in the annually 500,000,000 tons of urban and rural domestic waste in China would be 34,952,500 tons (21,390,000 + 13,562,500). In case of the most appropriate ratio of organic and inorganic nutrien
33、ts for organic-inorganic compound fertilizers (1:1), the potential amount of organic-inorganic compound fertilizers from food waste in China approximates at 69,905,000 tons. </p><p> Granulated organic-ino
34、rganic compound fertilizers are efficient, high-quality slow-release fertilizers. Slow/controlled release fertilizers usually cost 3-9 times more than ordinary fertilizers outside China, and 2-8 times more than ordinary
35、chemical fertilizers, known as “unaffordable fertilizers”. By June 2012, the price of urea in the domestic market has been stabilized at around RMB 2,300/t. Given the price of urea is RMB 2,000/t, then the potential valu

37、ronmental pollution and resource waste. According to Table 1, waste plastics accounted for 13.11% of domestic waste in the eight urban districts of Beijing, so the total amount of plastics in urban domestic waste in Chin

39、eversible and recyclable multipurpose materials which are mainly made of wood fibers and plastics (plastic resin: 30-75%; wood fibers: 25-70%). Wood-plastic building templates made of waste plastics (30%) and wood chips
40、 (70%) have already been developed in China, which means 126,870,000 tons of wood-plastic boards can be produced from the 38,060,000 tons of waste plastics. Assuming wood-plastic templates cost RMB 5,760/t [20], the pot

47、sposal of such waste are seldom mentioned in domestic research documents. As far as resource recycling is concerned, it is a rich cellulosic resource with stable sources. It is practical to produce fuel ethanol from sepa
48、rately-collected waste toilet paper through centralized disposal. </p><p> In industrially developed countries, there are 170 tons of cellulosic materials in every 250 tons of urban waste, which can produc
49、e about 36.5 tons of ethanol – 14.6 tons of ethanol out of 100 tons of cellulosic waste. The dry-basis separation test shows that 166.29kg of low-value unmarketable waste includes 8.75kg of toilet paper (5.26%). Without
50、public data, we assume waste toilet paper averagely accounts for 3% of urban and rural domestic waste, so there would be 15,000,000 tons of waste toil</p><p> US technologies such as Nitick and Penn-GE (com

53、; 3.4. Waste glass</p><p> According to Tables 1-2, glass accounts for 0.95% of urban domestic waste in China (200,000,000 tons x 0.95% = 1,900,000 tons). In rural domestic waste there is 4,530,000 tons of
54、 glass (300,000,000 x 1.51%). Therefore, there is totally 6,430,000 tons of glass in urban and rural domestic waste. Each ton of waste glass can produce 20,000 wine bottles. Conservatively, each bottle costs RMB 0.1, so
55、the market potential of waste glass is RMB 2,000 per ton, that is, RMB 12.86 billion in total. </p><p> In fact, waste glass may have higher economic value after resource recycling. Concrete with 35% of gla
56、ss aggregates from the US has proved qualified for the design requirements in its compression strength, shrinkage and water absorbability. Waste glass can also be made into glass-ceramic artificial marble slabs, building
57、 tiles, glass mosaics, heat-insulating and soundproof materials, etc. The potential value of the 6,430,000 tons of waste glass may be higher in case of a larger value-added pro</p><p> 3.5. Used clothes &
58、lt;/p><p> So far used clothes are seldom recycled as resources but directly buried or burned in most cases. Based on relevant data in Tables 1-3, the total amount of used clothes in urban and rural domestic w
59、aste in China is 8,110,000 tons, including 3,280,000 tons in urban domestic waste and 4,830,000 tons in rural domestic waste. The prices of used clothes offered on www.zz91.com from May 17 to June 17, 2012 ranged from RM

64、e is 1.24%, so we estimate there are about 6,200,000 tons of waste electronics in the 500,000,000 tons of domestic waste in China. The estimates of the Ministry of Science and Technology show that by 2010, there were 3,0
65、00,000 tons of waste electronics in China, and the figure will climb to 5,000,000 tons by 20</p><p> According to Table 1 and Table 3, paper accounts for 10.68% of urban domestic waste (about 21,360,000 ton
