The promotion results of various cleaning projects from August 31, 2013 until August 30, 2014 are as follows:
1. Implementation results of street cleaning and sweeping program:
Based on the annual street cleaning and sweeping program done by the private sector, a total accumulation of 57,376.12km and 27,885.62km of streets had been cleaned and swept this year, respectively. They accounted for a cumulative rate of 106.25% and 103.28% of street cleaning and sweeping achievements, respectively. Coupled with 280,962.2km of street cleaning and sweeping done by the public sector, a grand total of 366,223.94km of streets had been cleaned and swept by private and public sectors this year.
2. Benefits estimation of street cleaning and sweeping to contamination reduction:
An accumulation of 366,223.94km of streets had been cleaned and swept this year. Based on the estimated reduction formula (reduction = street cleaning and sweeping distance × reduction coefficient) of Environmental Protection Administration (EPA), a total of 5,053.86 metric tons of TSP, 959.5 metric tons of PM10, and 222.29 metric tons of PM2.5 can be reduced this year.
3. Effectiveness evaluation of street cleaning and sweeping:
To analyze the dust removal situation and assess the reduction effectiveness of street cleaning operation, a street dust analysis was done before and after the street cleaning program. The sampling results of this study on 30 representative roads show that the average silt loading before cleaning and sweeping was 0.397g/m³, and the average total street dust amount was 1.775g/m³. With average silt loading amount of 0.242g/m³ and average total street dust amount of 1.022g/m³ after the cleaning and sweeping program, it has found that the silt loading amount has reduced with an average total of 38.27%, and the street dust loading amount has reduced with an average total of 41.53%. Based on the reduction rate before and after street cleaning, the purpose of street cleaning operation to reduce street dust loading conducted by the study has reached its preliminary effectiveness, thereby improving the air quality.
4. Dirty road rating survey:
To master and reduce the dirty road rating of Taoyuan County to serve as a reference basis in planning the street cleaning and sweeping routes, a total of 2,070 roads with a total distance of 5,841.1km had been investigated this year. The proportion of A-class roads has gradually dropped from 87.1% in September 2013 to 67.9% in February 2014. After implementing the pollution sources elimination and strengthening the cleaning and sweeping frequency measures, the proportion of A-class roads has gradually increased to 91.2% in August 2014.
5. On-site verification of street cleaning and sweeping program:
To ensure that the street cleaning and sweeping program are able to meet with expected implementation effect, an indefinite-time and indefinite-spot prevalence survey was conducted by our team on street cleaning and sweeping program. A total of 624 on-site checks were done on vehicle trips of road sweepers.
6. Public satisfaction questionnaire survey:
To understand the perception, attitude and evaluation of the public of Taoyuan County on street dust cleaning and sweeping program done by EPA to serve as an important reference basis in promoting relevant policy development, business promotion, and residents communication, 500 questionnaires (valid number of copies) were distributed by the study to homes where the streets in front of them had been cleaned and swept. The survey results indicate that 66.4% of respondents reflected “acceptable” on the current status of street dust and garbage, and 68.1% of residents responded that they “witnessed” the private sector performing the street cleaning and sweeping program entrusted by EPA.
7. Demonstration and promotion of street cleaning and sweeping in promotion conference:
To allow the street cleaning and sweeping operators of Taoyuan County to understand the purposes, effectiveness and standard operation procedures of street cleaning and sweeping program, a demonstration and promotion conference was done by our team on 27 November, 2013 at Jhongli City Clean Team. It was implemented by means of presentation, dynamic demonstration and discussion, etc. Through issue discussion, the advantages and disadvantages of the current cleaning and sweeping program were proposed, and various improvement projects and effective proposals were offered by our team to help draft the future effective cleaning and sweeping program. The aims are to improve the county’s dirty road conditions, and further reduce particulate emissions and improve the air quality to reach the final goal of global sustainable development.
