Waste management involves collecting, transporting, disposing, recycling and monitoring waste generated through human activities.
General waste management techniques are:
It involves having the waste buried off in empty, deserted locations outside the city. Dumped waste is made to undergo compression to enhance the density and make the fill stable. It is later covered to discourage vermin growth. A gas extraction system is customarily installed to exact the gas (arising out of decomposition) through a burrow pit.
Waste is exposed to high temperature to trigger combustion and ultimately reduce to ash, gas and heat energy. Toxic wastes from industry are thermally treated in furnace and boiler to extract energy. This method is useful where land is scarce. Gasification and Pyrolysis methods involve heating waste in short supply of oxygen at high temperature inside a pressurized and sealed vessel. The resultant residue is used for energy generation.
Paper, plastic, PVC and other homogenous products can be recycled to put them in use in a new garb. This also rids the environment of non-biodegradable, chemical wastes that significantly disturb the ecological balance.
- Biological reprocessing
Wastes of organic origin are made to undergo biological decomposition and re-used as compost or mulch for agriculture and landscaping. Gas collected is used for electricity generation.
- Waste Reduction and Avoidance
The stress is on increased use of second hand products, repaired products and reducing the use of complex disposable items to keep a tab on waste generation in abundance.
- Recycling Solutions
Recycling is a superlative way to capitalize on accumulated waste by chemically treating it to make it fit for re-use. Recycling equipment make the waste processing method streamlined and cost-effective.
Types of Waste Equipments
They induce loose trash compaction by remarkably augmenting the waste density through elimination of air content prominently.
Compactors come in diverse forms to execute specific types of waste compression. Important variants are OUTDOOR TRASH COMPACTOR, INDOOR TRASH COMPACTOR, HIGH RISE COMPACTORS, BIN COMPACTORS, COMPACTING DUMPSTERS, AUTOMATIC COMPACTING RECEPTACLES, PRE-CRUSHERS, SPECIALTY COMPACTORS, STATIONARY COMPACTORS and SELF-CONTAINED COMPACTORS.
Compactors can score an average of 4 to 1 compaction. The chamber capacity of collecting container varies widely depending on application type.
They can help tremendously in bringing down the weekly trips of dumpsters. The dumpster size can also be significantly reduced to give a neat look to the industrial area. The amount of trash generated in an industrial unit for a given period can be fairly gauged by weighing the compacted mass produced by compactors. It can result in huge savings for the companies as trips to dumpsters as well as hauling cost is reduced. Besides, compactors help tremendously in improving the waste processing efficiency.
Compactors are used for generic wastes produced indoor and outdoor, in residential and commercial units, which have the potential of occupying significant space.
Solutions to Recycling
Balers are used for volume reduction of wastes and separating recyclable items from the waste stream.
Loose and sprawling recyclables can be baled to occupy significantly less space. Volume reduction also leads to better recyclable processing. Business units get an insight into the type of material causing maximum waste generation that enables them to take steps to curb the problem.
The different types of balers are low profile baler (intended for operation with less than normal ceiling height), conveyor system balers (applicable for ultra-high volumes), high density balers (for baling tough recyclables), specialty balers (designed with specific purpose in mind like baling bottles, soft drink cans), high production balers, extra density balers, cardboard, plastic, metal balers and others.
Balers are particularly useful for handling recyclables pertaining to metals, plastics, cardboard and other materials.
Shredders have useful application in industries. These help to disintegrate waste into small bits, which are easy to transport. The shredded output can serve as essential raw materials for other strategic production processes. Tire recycling is useful for a wide array of areas ranging from preparing playground surfaces to asphalt. Micro residential communities can drive home the same benefits as industries with shredders.
Shredders can be used for a variety of materials such as paper, plastic, debris, metal, electronics and even hazardous substances like radioactive waste.
Various types of shredders are designed based on the functions they execute. Widely used versions are grinders, granulators, chippers, hammer-mills, specialty shredders, shear shredders, and all purpose shredders.
Summary: Using waste and recycling equipment can significantly reduce waste processing and managing costs. Industries that make use of recycling equipment are also eligible for tax incentives.
