Recently, the rubbish low carbon that the reporter holds at Suzhou learns on general management seminar, china established town 2017 city life changes rubbish harmless change processing rate to achieve 96.6% , burn among them occupy about 41% , fill bury about 56% , can appear in rubbish processing process however a variety of greenhouse gas arrange an issue, the carbon related to its trades the project is not impressive however.
In a few kinds of way that rubbish handles, the volume of greenhouse gas platoon that writes the generation that bury place is highest, can release methane directly (CH4) , filling the commonly used ooze drop fluid in burying to adjust in ooze drop fluid a 2 oxidation nitrogen also can be discharged in the library (NO2) with CH4. And the effect that although relatively clean rubbish burns,also can add fossil fuel to support combustion with rising, if assist fuel, ignition to wait with oil, these fossil fuel can produce CO2 in aflame, and rubbish itself combustion also can produce the gas such as CO2, NO2. In the meantime, burn the ooze drop juice that place of rubbish of mill store hole produces ferments CH4 also can arise in the process in oxygen of be disgusted with.
So far, china already threw the plant of life garbage power that run to make an appointment with 332, total processing capability is day of 340 thousand tons of ／ , installed capacity already exceeded 7060MW. On the whole, garbage power scope is not little, the potential that decrease a platoon is tremendous, as the industry that the industry generates electricity to become the first batch to bring into countrywide carbon market by 2017, carbolic market decreases a platoon to also make a person expect as market tool implementation. So, carbon trades to handle an industry to affect to rubbish after all how, rubbish handles the greenhouse gas of the industry to discharge the difficulty of the business accounting that monitor to be in, these make the central point that the personage inside course of study pays close attention to most.
Inside alive bound limits, rubbish processing industry participates in carbolic market to application offsets the mechanism is mixed bring into two kinds of forms directly. The moving mechanism with main set and methodology system are adopted on international, the project that accords with a condition partly can develop a mechanism through cleanness (CDM) examine and verify. And be in China, carbolic market also burns rubbish generate electricity the project brings into application to put on record registered carbon is quits project, relevant project arises " nuclear card reduces an amount of one's own accord " (CCER) can enter the market to trade.
All the time since, project of CDM of domestic carbon market has rubbish to handle the methodology of the industry, but suffer global carbon to trade the influence of price fall, chinese clean the sources of energy develops a mechanism (CDM) industrial market development is in low ebb. Change according to national hair appoint the statistic of the website, up to now, china shares CDM project 5074, 1.44% what fill the benefit that bury gas to hold sum total of Chinese CDM project with the project. Be in accordingly home market, the project decreasing a platoon of CCER is the main aspect that rubbish handles an industry to share carbolic market. National hair changes appoint the data of the website shows, in domestic CCER authorized project, total of order of waste disposal category 180, 6% what hold sum total, be next to on the amount but project of second birth energy (71% ) with avoid methane to discharge category to look.
According to technical adviser of German international Cooperation Agency Zhang Zheng is analysed, rubbish processing project is not active in domestic carbon market, as a result of,one part reason is every pilot do not trade jointly, restrict somewhat to project type, the part is pilot accept this provincial CCER item only. In the meantime, CCER trades the price also is not made public like carbolic quota price transparent, end by this year July, the CCER that the country clinchs a deal is 140 million tons about, among them of the half clinch a deal the quantity comes from Shanghai, but pilot province city only Shanghai, Beijing made public CCER trade the price. She points out, last year March 17, national hair changes appoint ever suspended CCER project accepting, the hope undertakes on the system a few reform innovate, but at present new project development is in backwater condition.
Be in likewise international market, the work of rubbish processing trade in carbolic market jerk is not tall also. Only New Zealand and Korea handle rubbish the industry bring into carbon to trade directly now in the system. New Zealand brought into rubbish to burn only, and Korea is a large combustion and fill bury a project to bring into carbon to trade in the system, and rubbish industry is discharged in Korea carbon trade occupy only in the system 2.2% , the amount is very limited.
To this, zhang Zheng thinks to be done not have inside alive bound limits bring into rubbish industry carbon trade directly systematic reason depends on, compare with posture of industry of electric power, the sources of energy, industry, its discharge capacity is relatively lesser. In the meantime, discharge at reducing a problem relatively, rubbish industry still has cause of other environmental protection, if the loop of rubbish is used, and prevent pollution of pair of soil, groundwater, airy. In a few developed countries, rubbish industry has been accused by canal of place of other policy tool, if there is rubbish to fill in the European Union,bury instruction and rubbish to fill bury duty, the action that trades because of this carbon is done not have so remarkable, "Nevertheless, the mainest is rubbish method of business accounting of gas of processing trade hot house is compared relatively complex, this is why the matter that major carbon arranges a system to did not bring into rubbish industry, " Zhang Zheng expresses.
So, rubbish handles the greenhouse gas of the industry to discharge the difficulty of the business accounting that monitor to be in after all. Investigate its reason, the monitoring business accounting of the project needs to have level of its business accounting. Handle a trade to rubbish however, relative standard has not been refined. Carbon is achieved to cast Tang Jin of chief inspector of research and development to introduce in occupying, the detailed account that at present national level has computational greenhouse gas to discharge and international are energy-saving and normative standard (IECC) superintendency guideline, but calculating gas of greenhouse of rubbish industry itself to decrease a platoon still is thicker, the computational method that existing business accounting decreased a method to consult carbolic market reduces an amount, but application still needs to do at the city a few amend.
Next, rubbish handles a trade besides return related to trash processing industry related to energy industry, like heat addition, generate electricity, when because this a lot of projects are in,monitoring the quantity that decrease a platoon, the methodology that except application trash handles still needs to consider to generate electricity the methodology of the industry. For the business accounting that reduces an item to greenhouse gas, methodology is the fundamental standard that reduces a platoon, it set the source type, attrib border, standard that is one a complete set of, but comparative and other industry, the methodology structure that rubbish handles is very complex. "For example but second birth the sources of energy generates electricity have its methodology, but if fill,bury gas to generate electricity with but second birth the sources of energy generates electricity to be used jointly, cannot use onefold methodology, " Tang Jin points out.
Divide this beyond, the applicable condition of methodology and border decide harder also, once include a requirement improper, can bring into discharge capacity of a lot of itself not quite but computation rises very complex, computation rises the error is bigger discharge a type. Tang Jin handles way with a variety of rubbish (ACM0022) for exemple explanation, ACM0022 is an integrated methodology, apply to oxygen of compost, be disgusted with to digest, heat treatment, aerification, burn wait for multiple means, but it does not apply to rubbish to burn however the case that the quantity of heat of generation uses at cement industry. Because,this is if be used at cement industry, calculation of the quantity that decrease a platoon is more complex. Because this considers its are attrib border, this methodology by avoid. "Important is, must want to make the plan that monitor beforehand when each district undertakes survey, have when the plan add up to compasses sex and feasibility, and parameter is complete, ability assures to reduce an amount won't by overmeasure. Ability assures to reduce an amount won't by overmeasure..
