5 What is Waste Collection? Waste collection is a part of the process of waste management. It is the transfer of solid waste from the point of use and disposal to the point of treatment or landfill. Waste collection also includes the curbside collection of recyclable materials that technically are not waste, as part of a municipal landfill diversion program.

6 1. Greater Cairo administration corporation through service provider. Who collect solid waste in Greater Cairo administration? 2. Some private service provider

7 Types of solid waste in Greater Cairo The main types of solid waste in Greater Cairo administration are: 1. Household Waste 2. Commercial Waste 3. Medical Waste

8 Classification of collection system Based on the availability of service 1. House-to-House: Waste collectors visit each individual house to collect garbage. The user generally pays a double fee for this service. 2. Community Bins: Users bring their garbage to community bins that are placed at fixed points in a neighborhood or locality. MSW is picked up by the municipality, or its designate, according to a set schedule.

9 Classification of collection system 3. Curbside Pick-Up: Users leave their garbage directly outside their homes according to a garbage pick-up schedule set with the local authorities (secondary house-to-house collectors not typical). 4. Self Delivered: Generators deliver the waste directly to disposal sites or transfer stations, or hire third-party operators (or the municipality).

10 Types of Collection system Haul container system (HCS) Stationary container system (SCS)

11 Hauled Container System An empty storage container (Known as a drop-off box) is hauled to the storage site to replace the container that is full of waste, which is then hauled to the processing point, transfer station or disposal site.

12 Stationary Container System In this system, containers used for the storage of waste remain at the point of collection. The collection vehicles generally stop alongside the storage containers, and collection crews load the waste from the storage containers into the collection vehicles and then transport the waste to the processing, transfer or disposal site.

13 Objectives This research aims to headline a new method of waste management with low technology and high incorporate of stake holders, the goals can be stated as a new strategy for disposal of household waste. Kigali Convention Center- Rwanda 25-29th September,

14 Historical Background The concept presented in this research was sent as an idea in 1996 to the Al-Ahram journal, as on of many ideas, that could apply to regulate the traffic and circulation and maintain cleanliness as well as the security of the streets, and make them always occupied by movement and life throughout the 24 hours.

15 Historical Background concept is how to sustain continues funding from houses. Increase the security of society over the 24 hours by sustain the outstanding of the workers in the streets. Decrease the unemployment in the society.

16 Historical Background The Government at that time taking the idea of collecting funds and left the rest of the concept.

17 Methodology The inductive approach had been done in the theoretical section of this study, in the practical production part, two different methods were used; the first is the inductive approach in data gathering and quantifying the issues, another required data had been collected with a survey; which was designed especially for this purpose. Comparative approach was done to analyze the quantitative data and deductive approach had been done to result from the alternatives and determine the best alternative; which only will be mentioned in this study Kigali Convention Center- Rwanda 25-29th September,

18 Methodology Gained Objectives may be concluding as the following: Security factor; from main arterial ways to all streets, roads,, small routes will be occupied 24 hours a day. All kinds of unwanted and recyclable wastes will be collected and treated appropriately. Kigali Convention Center- Rwanda 25-29th September,

19 Methodology Gained Objectives may be concluding as the following: Economic factors; one of the main obstacles and difficulties in the solution is the fund problem, this point had been solved by a suggestion to add one $ (about EP) to the pile of electricity, this will be a strict contract between refuse contractor and residents. Kigali Convention Center- Rwanda 25-29th September,

20 Methodology Gained Objectives may be concluding as the following: Socio economic factors, reduce long-term unemployment rates, this study suggests a relatively large number unskilled labor beside few qualified employers. Context scheme, no high technology will be needed, the suggested utilities are shovels, sweepers, ax, garden wire handle rakes, 3 wheel cargo utility bike (tricycle with big basket), multi sized garbage bags, etc. Kigali Convention Center- Rwanda 25-29th September,

21 Methodology Gained Objectives may be concluding as the following: The clean of sidewalks and the streets sides form Sand and all disposed material which make the streets ready for any flooded rains or emergencies specially in winter. Places of waste or garbage collection will be a tremendous source of income for the project Kigali Convention Center- Rwanda 25-29th September,

22 Results and Discussions Information and Decision Support Center (IDSC) concluded that, the volume of garbage in the homes of about 13.8 million tons in the 2010, the Cairo governorate alone attracted to about 39.4% of the total amount of trash generated, houses with a total of 5.4 million tons. Kigali Convention Center- Rwanda 25-29th September,

23 THE MAIN ELEMENTS OF THE PRACTICE CAN BE CONCLUDED IN THE FOLLOWING POINTS According to the census of Greater Cairo the total population is 27,500,000 persons, in other words, the budget of this project can be easily calculated as the following: The total amount of the compound per month = The total number of residential units the collected money from each house = the total budget residential units 1 $ = US $

24 THE MAIN ELEMENTS OF THE PRACTICE CAN BE CONCLUDED IN THE FOLLOWING POINTS = EP / month this is the monthly received money set aside 5 million pounds per month to buy tools and equipment and maintenance, etc. The remaining EP / month.

25 THE MAIN ELEMENTS OF THE PRACTICE CAN BE CONCLUDED IN THE FOLLOWING POINTS 2 million pounds spare a month remaining reserve crises become EP / month by dividing the EP / month to 3000 pounds on average as a salary for each worker, economically this is good average if it was compared with Egyptian wages, we find that the number of refuse workers will be run in the field of direct action. Technical work, and professional work as well as about 2000 others in the field of management and follow-up.

26 THE MAIN ELEMENTS OF THE PRACTICE CAN BE CONCLUDED IN THE FOLLOWING POINTS The Evolving Urban Form: Cairo, New Geography, 13 June 2012, retrieved 9 Oct 2015 estimated number, due to the lack of data and the increasing number of population between the last census 2006 and the time this research done 2017.

27 THE MAIN ELEMENTS OF THE PRACTICE CAN BE CONCLUDED IN THE FOLLOWING POINTS The total length of streets in Cairo is about (25000 km) calculated by google maps. If we divide the total work time into three shifts this means that Cairo needs every 8 hours; a number of workers can clean the (25000 km). This research assumes that every single worker can clean and monitor (1.33 km) in every shift, this small relative length may make the work highly achieved and perfect. Each worker will do his task manually, and use only the simple tools mentioned above, this lead to reduce the cost and reduce the environmental pollution.

28 Tools & Method of collection No Garbage truck or dustcart because the hydraulic compressors may restrict the Waste sorting before recycling, here the 3-wheel cargo utility bike (tricycle with big basket) will have more value. Some tools can be designed by students of engineering faculties, this may increase the effective participation of residents. All the last points are introduction, the recycling will be the main income source, for the Emergency cases, to develop and maintain the city, to preserve the urban environment and upgrade it, etc. Context scheme, no high technology will be needed, the suggested utilities are shovels, sweepers, ax, garden wire handle rakes, 3 wheel cargo utility bike (tricycle with big basket), multi sized garbage bags, etc.

29 Three main fazes to collect and classify the refuse The first; due to behavioral factor from the entrances of building any time and every day, and as a higher service from the apartment door for 50 % increase in fees (1.5 US $) The second; Collection stations will be distributed evenly and according to the average amounts of collected garbage on each street.

30 Three main fazes to collect and classify the refuse The third; Main collection station will be at main arterial routes. The Garbage sorting and classification may be done in the second stage of collecting under the supervision of the worker in a safe manner by the diggers Inserted.

31 Problems in Collection System On Street Container & Passengers Problem

32 Conclusion This study may lead to the following: High-security levels in the streets due to the continuous work hours. The reduction of harmful Insects and rodents. Improve the sanitary conditions and QoL in the city. Highly degrees of recycling and disposal. High un skills employment rates for the short and long-term. Kigali Convention Center- Rwanda 25-29th September,

33 Conclusion This study may lead to the following: Increase the social behavior and improve the environmental awareness of the people. Increase the loyalty and participation between the residents and the government. Places of waste or garbage collection will be a tremendous source of income for the project as well as about 3000 jobs at an average monthly wage of 6,000 pounds per capita.
