Pichtel “A solid material possessing a negative economic value, which suggests that it is cheaper to discard than to use.”  Volume 40 of The US Code of Federation Regulations (40 CFR 240.101) “Garbage, refuse, sludges, and other discarded solid materials resulting from industrial and commercial operations and from community activities. It does not include solids or dissolved material in domestic sewage or other significant pollutants in water resources, such as silt, dissolved or suspended solids in industrial wastewater effluents, dissolved materials in irrigation return flows or other common water pollutants.”  DEFINITION OF SOLID WASTE  RA 9003 “shall refer to all discarded household, commercial waste, non-hazardous institutional, ports / harbour and industrial waste, street sweepings, construction debris, agriculture waste, and other nonhazardous/non-toxic solid waste. Unless specifically noted otherwise, the term “solid waste” as used in the Act shall not include: a) waste identified or listed as hazardous waste of a solid, liquid, contained gaseous or semisolid form which may cause or contribute to an increase in mortality or in serious situations, incapacitate or cause irreversible bodily damage or acute/chronic effect on the health of persons and other organisms; b) infectious waste from hospitals such as equipment, instruments, utensils, and fomites of a disposable nature from patients who are suspected to have or have been diagnosed as having communicable diseases and must therefore be isolated as required by public health agencies, laboratory wastes such as pathological specimens (i.e., all tissues, specimens of blood elements, excreta, and secretions obtained from patients or laboratory animals), and disposable fomites that may harbor or transmit pathogenic organisms, and surgical operating room pathologic specimens and disposable fomites attendant thereto, and similar disposable materials from outpatient areas and emergency rooms; and c) waste resulting from mining activities, including contaminated soil and debris.  CATEGORIES OF SW  Municipal solid waste  Hazardous waste  Industrial waste  Medical waste

Pichtel)  PUBLIC HEALTH ASPECTS Solid wastes may contain:  Human pathogens – diapers, handkerchiefs, contaminated food and surgical dressings  Animal pathogens – waste from pets  Soil pathogens – garden wastes  Who are at risk?  General public  SWM facility employees  For a person to be at risk from solid waste pathogens  An infectious dose of pathogens must be present.  There must be a transmission route of the pathogens to the person, i.e. aerosol, faecal-oral route, hand to mouth, etc.  The person must have no immunity to the pathogen.  MUNICIPAL SOLID WASTE (MSW)  Domestic waste or household waste  Generated within a community from several sources, and not simply by the individual consumer or a household.  Originates from residential, commercial, institutional, and municipal sources.  Highly heterogeneous and include durable goods (e.g. appliances), non-durable goods (newspapers, office paper), packaging and containers, food wastes, yard wastes and miscellaneous inorganic wastes. (J. Pichtel)  MUNICIPAL SOLID WASTE (MSW)  Often divided into 2 categories:  Garbage – results from growing, handling, preparation, cooking and consumption of food; putrescible material, i.e. can decompose quickly through microbial reactions to produce bad odors and harmful gases.  Rubbish – nonputrescible; combustible and non-combustible such as cans, papers, brush, glass, cardboard, wood, scrap, metals, beddings, yard clippings, crockery (pottery)  MSW Generation as a Function of Source  Sources and Types of Solid Wastes  SOLID WASTE MANAGEMENT  Shall refer to the discipline associated with the control of generation, storage, collection, transfer and transport, processing, and disposal of solid wastes in a manner that is in accord with the best principles of public health, economics, engineering, conservation, aesthetics, and other environmental considerations, and that is also responsive to public attitudes. (RA 9003)  Functional Elements of SWM  Guiding Principles of SWM  Waste is a resource.  Overall concept: Everything must go somewhere.

 When waste is thrown away, it will not disappear or get destroyed. It will only end up somewhere else, in one form or the other. There is really no such thing as “throw away” material. When waste ends up where it is not supposed to be, it becomes useless, causes pollution and poses health risks. When it is used and put in the right place, it becomes a valuable resource.  Guiding Principles of SWM  Waste prevention is better than waste regulation control.  Waste management as end-of-pipe approach failed to significantly solve SWM problems.  Waste prevention addresses waste problems prior to waste generation.  Waste avoidance  Reuse  Recycling  Waste recovery  Guiding Principles of SWM  There is no single management and technological approach to solid waste. An integrated SWM system will best achieve SWM goals.  A community’s waste stream is made up of several components (i.e. reusable, biodegradable, recyclable, toxic, hazardous, etc.) that can be managed and disposed separately. Thus, an integrated SWM system using a combination of approaches (e.g. source reduction, reuse, recycling, composting, waste-to-energy technologies, volume reduction, combustion and landfilling) may be used.  Guiding Principles of SWM  All elements of society are fundamentally responsible for solid waste management.  Those who generate waste must bear the cost of its management and disposal.  SWM should be approached within the context of resource conservation, environmental protection and health, and sustainable development.  SWM programs should take into consideration the physical and socio-economic conditions of the concerned communities and be designed according to their specific needs.  INTEGRATED SWM defined as the selection and application of suitable techniques, technologies and management programs to achieve specific waste management objectives.  3Es  Engineering  Education  Enterprise  Hierarchy of Integrated SWM  Planning for ISWM  Proper mix of alternatives and technologies  Flexibility in meeting future changes  Monitoring and evaluation  Management Issues  Setting workable but protective regulatory standards  Improving scientific methods for interpretation of data  Identification of hazardous and toxic consumer products requiring special waste management units  Paying for improved waste management units  Designating land disposal units at or near large urban centers

 Establishing and maintaining more qualified managers to develop and operate waste management units  Future Challenges and Opportunities  Changing consumption habits in society  Reducing the volume of waste at the source  Making landfills safer  Development of new technologies  BRIEF HISTORY OF WASTE MANAGEMENT  Earliest Civilizations  Mesopotamia, Egypt  8000 to 9000 BCE  Dumps were established away from settlements – probably located so that wild animals, insects, and odors would not migrate to populated areas.  Minoans (3000 to 1000 BCE) – placed their wastes, covered periodically with layers of soil, into large pits, thus operating the first proto-sanitary landfill.  BRIEF HISTORY OF WASTE MANAGEMENT  2100 BCE – cities on the island of Crete had trunk sewers connecting homes to carry away wastes.  Egyptian city of Heracleopolis – wastes in the “non-elite” section were ignored, while in the elite and religious sections efforts were made to collect and dispose of all wastes, which usually ended up in Nile River.  At Kouloure in the ancient Crete capital of Knossos (ca. 1500 BCE) – an effective composting effort was established in pits.  BRIEF HISTORY OF WASTE MANAGEMENT  800 BCE – old Jerusalem established sewers and had installed a primitive water supply.  In Indus valley, city of Mohenjo-daro – houses were equipped with waste chutes and trash bins, and may have had waste collection systems.  Harappa, in Punjab region, now part of modern-day India – installed toilets and drains in the bathrooms.  Many Asian cities – collected wastes in clay containers which were hauled away.  BRIEF HISTORY OF WASTE MANAGEMENT  First recorded regulations for SWM – were established during the Minoan civilization.  Around 2000 BCE – Israel provided guidelines as to how to manage wastes, instructions for the management of human waste are provided in the Bible (Deuteronomy 23:12-13).  By 200 BCE – many cities in China employed “sanitary police”, who were responsible for the enforcement of waste disposal laws.  BRIEF HISTORY OF WASTE MANAGEMENT  Greece  5th century BCE – Greek municipalities began to establish town dumps that were maintained in a relatively orderly condition.  Garbage normally consisted of food waste, fecal matter, and abandoned babies (e.g. malformed or illegitimate).

 In Athens, ca. 320 BCE – each household were responsible for collecting and transporting its wastes. Residents were required by law to sweep the streets daily, and it was mandated that wastes be transported to site beyond the city walls.  BRIEF HISTORY OF WASTE MANAGEMENT  Greek and Persian scholars – among the first to suggest an association between personal hygiene, contaminated water, spoiled food, and disease outbreaks and epidemics.  Hippocrates (ca. 400 BCE) and Persian Ibn Sina (980-1037 CE) suggested a relationship between waste and infectious disease.  LEGAL ASPECTS OF SOLID WASTE MANAGEMENT  US – SWM started from Solid Waste Act of 1965, Resource Conservation and Recovery Act (RCRA) of 1976, up to California Assembly Bill 939 in 1993 – aimed to promote solid waste management and resource recovery and provide guidelines for collection, transport, separation, recovery and disposal.  PHILIPPINE LAWS AND REGULATIONS RELATED TO SWM  Commonwealth Act No. 383 – An Act to punish the dumping into any river of refuse matter or substances of any kind whatsoever that may bring about the rise or filling in of river beds or cause artificial alluvial formation.  PHILIPPINE LAWS AND REGULATIONS RELATED TO SWM  PD 1152, Philippine Environment Code – Comprehensive program on environment protection and management by establishing specific environmental management policies and prescribing environmental quality standards in the Philippine Environment Code.  PHILIPPINE LAWS AND REGULATIONS RELATED TO SWM  PD 984, Pollution Control Law – Provides the specific guidelines and implementing rules and regulations on liquid waste disposal after physical or chemical treatment in accordance with existing rules and regulations.  PHILIPPINE LAWS AND REGULATIONS RELATED TO SWM  PD 825, Penalty for Improper Garbage Disposal Providing penalty for the improper disposal of garbage and other forms of uncleanliness and for other purposes.  PHILIPPINE LAWS AND REGULATIONS RELATED TO SWM  PD 856, Code of Sanitation Provides the rules on disposal of refuse in food establishments, and for construction of markets and abattoirs.
