Waste Disposal

OPEN BURNING AND DUMPING OF SOLID WASTES

Page 2: Environmental Engineering (disposal and treatment of solid wastes)

Waste Disposal Waste Disposal is the management

of waste to prevent harm to the environment, injury or long term progressive damage to health. Disposal of waste is where the intention is to permanently store the waste for the duration of its biological and chemical activity, such that it is rendered harmless. 

Page 3: Environmental Engineering (disposal and treatment of solid wastes)

Open dumping Open dumping Discarding trash or unwanted items

anywhere except state permitted landfills, transfer

Examples of waste which is often dumped are household building debris, construction and demolition waste, household garbage, appliances, furniture, tires, plastic, cardboard and hazardous waste.

Page 4: Environmental Engineering (disposal and treatment of solid wastes)

What is the best alternative to open dumping?

Just like with regular landfills, the majority of refuse in open dumps can be recycled, composted or reused.

People can buy in bulk to reduce packaging waste. Glass, aluminum and plastic containers, newspaper and

corrugated cardboard can be taken to the nearest recycling center.

Materials good for composting include uncontaminated and untreated natural growth solid wastes, such as tree limbs, stumps, leaves, grass clippings and sawdust that is derived from processing untreated, natural wood.

What is the best alternative to open dumping?

Non-meat kitchen scraps can easily be added to the compost pile or vermicultured (composting using red worms).

Furniture and appliances can be recycled. Various services recycle the parts or refurbish them for resale. Some Solid Waste Management Districts include a list of local services on their Web sites.

Unusable tires should be given to an authorized tire disposal agent. Your local tire retailer will know of a tire disposal service which can take used tires. A minimal fee will be charged to ensure that the tires will be recycled properly and not placed into a hazardous tire dump.

What are the consequences of open dumping? Or Why is open dumping bad?

The environmental damage to the soil and water can be both significant and irreversible.

Piles of waste take away from naturally beautiful landscape. Open dumping can also lower property values of surrounding homes.

Open dumping contaminates the environment and destroys beautiful scenery.

What are the consequences of open dumping? Or Why is open dumping bad?

Household Hazardous Waste (HHW), such as paint, pesticides and other toxic chemicals, can be found in open dumps.

No measures are made to prevent rainfall from carrying the chemicals and HHW into the water table and the local drinking water.

Household garbage, which may include food scraps and dirty diapers, attracts vermin. Discarded tires collect water and form the perfect breeding area for mosquitoes.

What is Open Burning?

Open burning is any burning outdoors that does not pass through a stack, duct, or chimney. This includes outdoor residential, agricultural, and prescribed burning.

Open burning also applies to material that is burned in burn barrels, air curtain destructors, or other such devices.

Open Burning

Page 10: Environmental Engineering (disposal and treatment of solid wastes)

Why Limit Open Burning? Smoke from open burning

pollutes the air and is unhealthy to breathe

Potential health effects include Lung and Eye irritation Headaches, Dizziness Asthma attacks Coughing and wheezing

and Even death in some cases

Page 11: Environmental Engineering (disposal and treatment of solid wastes)

Breathe… Don’t Burn!

Outdoor fires pollute the air

Smoke is unhealthy to breathe

Recycle or properly dispose of waste

Page 12: Environmental Engineering (disposal and treatment of solid wastes)

Health and Other Impacts  Smoke from open burning pollutes the air with a mixture

of fine particles and gases. All types of open burning can affect the air we breathe. What goes up doesn’t immediately go away. And burners may be held legally responsible for any damages or injury caused by open burning.Smoke from all types of open burning can:

Make breathing difficult Cause or contribute to serious health problems Impair visibility Create road and aviation safety problems Be a nuisance to neighbors

Open Burning Alternatives Compost yard waste

Chip tree limbs

Land clearing debris Haul to sawmill or pulpwood yard Chip or tub grind remaining material

Recycle or re-use non-vegetative material

Contact local solid waste facility

Page 14: Environmental Engineering (disposal and treatment of solid wastes)

Alternatives to Burning  Burning can waste valuable resources. To prevent this,

some open burning can be minimized through better planning, reuse, or recycling.

Yard trimmings and other vegetative matter can be composted.

Newspaper and cardboard can be recycled. wood waste can be turned into usable products such as

wood chips or paperboard. However, open burning may be necessary when reasonable alternatives do not exist.

This may be the case for some types of agricultural burning as well as prescribed burns on forest and rangelands.

 Types of Burning  Residential Solid Waste Burning Residents may burn solid waste (rubbish, tree leaves, yard

trimmings, gardening waste, etc.) if no scheduled house-to-house solid waste collection service is available and the burning is conducted on the property where the waste was generated.

Residents also may burn tree leaves, yard trimmings, or gardening waste if allowed by local ordinance or rule and conducted on the property where the waste was generated.

Page 16: Environmental Engineering (disposal and treatment of solid wastes)

 Types of Burning  Prescribed Burning Prescribed burning is the open burning

of forest and rangeland to accomplish land management objectives such as improving wildlife habitat, restoring or maintaining ecosystem health, and reducing fire hazard.

TREATMENT OF SOLID WASTES.

CHOICE OF TREATMENT SYSTEM FOR TREATMENT OF SOLID WASTES

Page 18: Environmental Engineering (disposal and treatment of solid wastes)

CHOICE OF TREATMENT SYSTEM FOR TREATMENT OF SOLID WASTES.

As there are number of solid wastes generating sources which are generating different types of solid wastes. So there are various types of treatment systems/technologies, have been developed for treatment of solid wastes.

However, recently developed alternative treatment methods are becoming increasingly popular. The final choice of treatment system should be made carefully, on the basis of various factors, many of which depend on local conditions:

Page 19: Environmental Engineering (disposal and treatment of solid wastes)

CHOICE OF TREATMENT SYSTEM FOR TREATMENT OF SOLID WASTES.

disinfection efficiency; health and environmental considerations; volume and mass reduction; occupational health and safety considerations; quantity of wastes for treatment and

disposal/capacity of the system; types of waste for treatment and disposal; infrastructure requirements; locally available treatment options and

technologies;

options available for final disposal; training requirements for operation of the method; operation and maintenance considerations; available space; location and surroundings of the treatment site

and disposal facility; investment and operating costs; public acceptability; Regulatory requirements.
