Transcript of Solid waste Management

Waste Management What is waste management? Waste Management
flows in a cycle: END Is the collection, transport, processing or disposal, managing and monitoring of waste materials. The term usually relates to materials produced by human activity, and the process is generally undertaken to reduce their effect on health, the environment or aesthetics. Waste management is a distinct practice from resource recovery which focuses on delaying the rate of consumption of natural resources. All wastes materials, whether they are solid, liquid, gaseous or radioactive fall within the remit of waste management Kinds of Wastes Solid wastes:
domestic, commercial and industrial wastes especially common as co-disposal of wastes
EXAMPLE Plastics Styrofoam containers Bottles Cans Paper's Scrap Iron's Liquid Wastes:
wastes in liquid form
EXAMPLE Domestics Washing Chemical Waste Oil Waste waste from ponds and
Manufacturing company
and other
Resources NATIONAL WASTE GENERATION, 2000-2010Classification of Wastes according to Monitoring their Effects on Human Health and the Environment Bio-degradable
can be degraded (paper, wood, fruits and others) Non-biodegradable
cannot be degraded (plastics, bottles, old machines,cans, Styrofoam containers and others) Waste management practices can
differ for developed and developing
nations, for urban and rural areas,and for
residential and industrial producers. Management
for non-hazardous waste residential and institutional
waste in metropolitan areas is usually the responsibility
of local government authorities, while management for
non-hazardous commercial and industrial waste is
usually the responsibility of the generator subject to
local, national or international controls. Classification of Wastes according to their Effects on Human Health and the Environment Substances unsafe to use commercially, industrially, agriculturally, or economically that are shipped, transported to or brought from the country of origin for dumping or disposal in, or in transit through, any part of the territory of the Philippines Non Hazardous Waste Substances safe to use commercially, industrially, agriculturally, or economically that are shipped, transported to or brought from the country of origin for dumping or disposal in, or in transit through, any part of the territory of the Philippines GARBAGE SITUATION IN THE PHILIPPINES: A Filipino generates between 0.3 and 0.7 kilograms of garbage daily depending upon income levels.
NCR and Southern Tagalog Region produce the highest amount of waste accounting for 23 and 13% of the country’s production.
70% of garbage is collected in Urban Areas and 40% in Rural Areas
13% of Metro Manila’s waste is recycled.
Nationally, only 2% of waste are disposed in sanitary landfills or controlled dumps. 10% are composted, and small portion is recycled. The rest is disposed in open dumps. NATIONAL WASTE GENERATION, 2000-2010 Monitoring
Collection Transportation
Processing Disposal / Recycle Monitoring Is identifying the waste management needs, identifying recycling opportunities and ways to minimize waste output, and reviewing how waste minimization is progressing. Through keeping records of the different waste streams, a customer can see the results of their efforts in becoming more environmentally friendly, and a more efficient business. Collection Involves the logistical organization to guarantee that bin containers will not overfill and waste sit time does not become too long. The correct bin container size and service frequency is a must to prevent overspill or excessive smell. The correct bins for different wastes must be available with sticker and bin color identification. Locks, chains, lids and bars prevent public access and non-trained personnel putting rubbish in the incorrect bins. Cooperation between the waste company and customer is vital. Bins must be accessible to the truck driver at the agreed times. Access to work premises outside work hours will cause an issue if unaddressed. Bin wheels can allow customers to move bins from convenient areas to serviceable locations. Transportation Is the organizing of waste transport vehicles with the authorization and ability to transport the specified wastes from a customer’s work residence to landfill or processing plant. A waste must be transported by the vehicle designed for it. For example, general waste requires a vehicle with thicker compacter walls, to that of a cardboard and paper waste transporting vehicle. Therefore, a customer may require a series of vehicles to meet their waste management needs. Vehicles, drivers, and companies need licenses and approval in certain Council Areas to transport waste. EPA standards need to be upheld as well as General Public Safety. Safety standards are vital to the transportation of clinical and hazardous wastes. Drivers must undergo training for emergency circumstances that may arise. Processing Involves the separation of recyclables for treatment, and then after treatment are packaged as raw materials. These raw materials are sent to factories for production. Non-recyclable wastes by-pass this step and are delivered straight to landfill. Liquid and hazardous wastes are delivered to treatment plants to become less hazardous to the public and environment. Disposal / Recycling Is the disposal of non-recyclables into landfill. Landfill sites must be approved by legal authorities. Legal authorities guarantee that specific wastes are buried at the correct depth to avoid hazardous chemicals entering the soil, water tables, water systems, air, and pipe systems. In this step the raw materials made from recyclables are produced and sold as products on the market. Companies can purchase such products to further sustain the environment and natural resources. In conclusion, waste management is a science that addresses the logistics, environmental impact, social responsibility, and cost of an organization’s waste disposal. It is a detailed process that involves human resources, vehicles, government bodies, and natural resources. Created by:
