In recent years，All parts of the country attach great importance to bet365 offer management，A series of policies have been introduced。In particular, the "Pilot Work Plan for the Construction of "bet365 offer-Free Cities" issued by the General Office of the State Council on December 29, 2018 promoted bet365 offer management work nationwide。However，The reality is not optimistic。As a pioneer area for bet365 offer management，Zhejiang Province’s garbage collection volume in 2019 still increased by 3% year-on-year.77%。How to break the situation？Some thoughts on bet365 offer management may be put forward through three typical cases。

　　“Brother Hu Model” constructs a smart bet365 offer and disposal system

Starting from 2017，The Yuhang District Government of Hangzhou began to purchase services from "Brother Hu Environmental Company" (hereinafter referred to as "Brother Hu")，Promote "simplified classification of people"、Enterprise complex points”，Gradually build a "one-stop front-end network、Recycle a chain、Scientific and comprehensive bet365 offer management system with smart supervision and one network。

First，Source “one-stop” recycling of all recyclables in residents’ homes，And collaborate to collect hazardous bet365 offer and bulky bet365 offer。Residents put all recyclables into special recycling bags，Through mobile App、WeChat、Submit recycling orders through recycling hotline and other methods，You can also leave recycling bags at your door，Waiting for the "Brother Tiger" service staff to come to weigh you regularly、Scan code、Recycle，Replace with new recycling bags。"Brother Tiger" service staff gives residents "environmental protection money" based on weight，And automatically credited to residents’ accounts。“Environmental protection gold” can be exchanged for daily necessities，To encourage residents to actively participate，The entire service process is strictly carried out in accordance with standardized operating specifications。Second，Collect、Transportation、sorting、Utilize "a closed-loop chain"，Realize garbage recycling，Turn bet365 offer into treasure。The industrial group at the back end of the chain can safely recycle all the garbage、Cleaning、Convert intensively and efficiently into renewable resources with utilization value，Recycling rate up to 98%，Harmless rate reaches 100%。Third，The intelligent supervision platform realizes the automation of supervision、Standardization and transparency，Improved the modernization level of the bet365 offer management and supervision system。The government can accurately monitor the bet365 offer management process in three aspects: the real-time amount of bet365 offer put in by each household、Real-time recycling volume of 47 types of recyclables subdivided by "Brother Tiger"，As well as the real-time whereabouts and resource utilization of these 47 recyclables，Accurately realizes garbage classification and recycling、clearance、Resource utilization and other multi-point and multi-faceted one-network supervision。

The characteristic of "Brother Hu Model" is to recycle all garbage except the kitchen and bathroom，commonly known as "dry garbage"，Established garbage classification and distribution、Classified collection、Closed-loop industrial chain of classified transportation and classified disposal，Internalize the social chain of bet365 offer disposal into the industrial chain within the enterprise，And guided by points，Realize residents’ domestic bet365 offer should be divided as much as possible、Application exhausted。Because the operation of "Brother Tiger" has strong economies of scale，Therefore it is more suitable for urban areas with relatively concentrated populations。

　　“American cockroach model” solves the resource utilization problem of perishable bet365 offer

According to relevant statistics，More than half of our country’s residents’ domestic bet365 offer is perishable bet365 offer (i.e. kitchen bet365 offer and food bet365 offer)，Not only is the quantity large, but it is also difficult to dispose of。Shandong Kunpeng Agricultural Development Co., Ltd., which started in Zhangqiu, Shandong, pioneered the breeding of American cockroaches，Disposal of perishable bet365 offer through biological methods，Methods to achieve resource utilization，A total of 42 patents have been obtained so far，Already in Hangzhou, Zhejiang and Jiangsu、Shanxi、A number of cities and counties in Anhui and Hubei have implemented or plan to implement。

On the one hand，This model focuses on the resource utilization of perishable bet365 offer。American cockroach has a mixed diet，Not picky about food，It can eat and squeeze out all the sweet, bitter, spicy and salty food bet365 offer，Full Digestion、No residue。American cockroaches are large eaters and can be fed food bet365 offer throughout their life cycle，It can be made into various biological feeds and protein powder，Used for comprehensive breeding。On the other hand，This model has a complete disposal process and high comprehensive benefits。Currently，The American cockroach breeding process uses a steel structure double-layer greenhouse，Collection breeding、Planting、Developing multiple photovoltaic power generation industries simultaneously。Periplaneta americana is cultured on the first floor of the greenhouse to extract insect powder (protein content is as high as 71.8%），Substitute imported fish meal (fish protein，Protein content 62%) used in feed。The second floor uses Periplaneta americana biothermal energy (27℃) to heat the second-floor greenhouse，Grow seedlings at low temperatures without worry、Planting Agaricus bisporus，Promote green agriculture。Photovoltaic power generation panels are installed on the top floor (a base that processes 100 tons of food bet365 offer per day，Annual power generation up to 1000 kWh)，Electric energy used for project lighting、Mechanical kinetic energy、Charging piles, etc.。Comparing greenhouses without photovoltaic panels，The photovoltaic panels used in this process absorb energy and reduce the temperature in the greenhouse by about 10°C to 20°C in summer，Greatly save energy consumption in planting，Increase production。Ammonia in American cockroach excrement、Nitrogen content up to 61.8%，Phosphorus、Potassium and other trace elements are stable in content，It is high-quality organic fertilizer，Has the function of repairing soil compaction。

The "American cockroach model" is characterized by focusing on the back-end biological disposal link，Using biological methods to fully utilize perishable bet365 offer resources，And has high comprehensive utilization efficiency。Due to the large area occupied by biological breeding，Suitable for rural areas、urban-rural interface、Development of urban areas with relatively abundant land resources。

　　“Xinxin Blue Mode” creates a terminator of stale bet365 offer

Hubei Xinxinlan Environmental Protection Technology Co., Ltd. (hereinafter referred to as "Xinxinlan") is a company specializing in construction and decoration bet365 offer、General industrial bet365 offer、High-tech enterprise for recycling domestic bet365 offer and bulky bet365 offer，Has unique technologies and advantages in the management and restoration of landfills。For example, the "Changshan Pass Project" undertaken by this company is a national "13th Five-Year Plan" science and technology special demonstration project，This is also the first major scientific and technological project established by the country for the recycling of solid bet365 offer and the management of stale garbage。

First，Focus on the research and development of bet365 offer back-end disposal technology，Realize full utilization of bet365 offer components。Xinxinlan relies on advanced technology，Construction and decoration bet365 offer、General industrial bet365 offer、Efficient screening of household bet365 offer and bulky bet365 offer，Separated into subsieve humus nutrient soil through coarse separation equipment、Inorganic aggregate、Metals and light objects on the sieve are classified into four categories。Among them，The humus nutrient soil under the sieve can be used for soil improvement after stripping away the contamination、Landscaping；Inorganic aggregate can be used to make cement mortar or road construction after being stripped of contamination；The metal can be recycled and reused after being stripped of contamination。

Secondly，Vigorously develop bet365 offer products，Can digest a large amount of various types of garbage。Xinxinlan will sort out the plastic、Light combustibles as raw materials，Producing new composite materials with environmental protection and superior performance indicators - "Simu" series products。Its “Simu” product has a total of logistics pallets、Three categories of building formwork and various industrial floors，These three types of products are all bulk products，Big market space，Demand exceeds supply。Because "Simu" products are hard and corrosion-resistant，It can also be widely used in railings in the future、Scenic area plank roads and even train sleepers and other projects，Broad application prospects satisfy the problem of digesting huge amounts of garbage。

Finally，Xinxinlan treatment process does not incinerate the entire process、No landfill，Able to fully utilize garbage without leaving any residue，Realized collaborative processing of all bet365 offer resources。Handle the whole process without getting angry、Fudu Shui、No secondary pollution，At the same time, it also greatly reduces carbon emissions，Is of great significance to the realization of the "double carbon" goal。Broad resource utilization prospects not only meet the large-scale bet365 offer management needs，Realize the green governance goal of fully recycling bet365 offer，Furthermore, the substitution of "Simu" products for other building materials has major strategic significance for "carbon emission reduction"。

Construction and decoration bet365 offer and old bet365 offer in landfills have always been the shortcomings of bet365 offer disposal，It is also an important factor restricting the sustainable development of cities，“Xinxinlan Mode” makes up for this shortcoming。Xinxinlan utilizes advanced technology，Developed a series of products，Provides an important way and market space for the resource utilization of garbage，Its “Simu” products are of extraordinary significance to the realization of the “double carbon” goal。

　　bet365 offer

July 2021，The National Development and Reform Commission issued the "14th Five-Year Plan for Circular Economy Development" (Fagaihuanzi (2021) No. 969)，Emphasized that resource recycling has become an important way to ensure my country’s resource security。In order to better make garbage a "right" resource，bet365 offer，This article has the following suggestions。

First，The government should become a “meta-governor”。On the one hand，The government should vigorously support the development of resource utilization enterprises，Leveraging the back end of the bet365 offer management chain，Construct a complete chain of bet365 offer management from source classification to back-end resource utilization。On the other hand，The government should speed up the construction of the legal system，Avoid gray areas，At the same time, supervision must be strengthened，Realize green governance of the entire industry chain。

Second，Encourage innovation、Adapt measures to local conditions，Let the market mechanism play a fundamental role。In less developed areas，The government can consider guiding renewable resource companies to integrate individual recycling stations，And small sorting plants that are outside the formal recycling system, etc.。At the same time，Government can be integrated through organizations、Vocational training and other methods to include corridor cleaners、Individual scavengers、Valid for actors including small and micro enterprises、Participate in the bet365 offer management chain in an orderly manner，Form diverse participation、The pattern of collaborative governance。

　Third，Reconstructing the bet365 offer management evaluation system based on resource utilization。Continuous improvement of residents’ living standards，And the pursuit of convenience in life (such as takeaway、The rapid increase in business volume such as express delivery) inevitably leads to the generation of garbage。The above cases tell us，Only by fully utilizing resources can we achieve the goal of building a “bet365 offer-free city”，Therefore, the ratio of bet365 offer that ultimately needs to be landfilled or incinerated should be used as the evaluation index，Promote local governments to make efforts in resource utilization，So as to make garbage a "right" resource，Promote the realization of resource recycling goals。
