Packaging waste today belongs to a dominant category in the waste conundrum. Thanks to food deliveries, on-line purchases and the need to make a product look good by better packaging, safe receipt of ordered goods by the customer and the increased use of disposables and the constantly growing use-and-throw products have all made the packaging waste to contribute more than 50% of the total waste. While recycling rate of containers and packages is reasonably high, the process of incinerating packaging waste is also equivalent to 50% of recycling rate.
A major category of packaging consists of plastic used in food packaging, which is a hallmark of the throw away culture. These are of course to be recycled and not incinerated. Wood, paper and plastics have significant heat values and are energy sources.
Incineration is the most hygienic method of reducing the volume and weight of solid wastes. The advantages are;
- Packaging materials like wood, paper and plastics (except PVC) do not require high quantities of fuel due to their inherent heat value
- Packaging is not hazardous waste that produces a high level of pollutants
- Negligible quantity of heavy metals are found in the ash after incineration
The kinds of packaging and other similar wastes we are talking about here for incineration are;
- Wooden crates and boxes
- Cardboard
- Product labels
- Confidential documents
- Drawings
- Soiled currency
- Cheque off-cuts
- Garden wastes and dry leaves
- Adhesive and insulation tapes
- Dry leaves
The model LD/MD/HD from Haat range are
These models are rightly called “free burning” primarily because they do not use any fuel. They utilize the calorific value of the waste to burn itself.
The design of these systems is such that it allows atmospheric air to enter the combustion chamber through various pre-determined orifices in the refractory. Once the waste is manually ignited, the pressure in the chamber drops, allowing atmospheric air to enter freely, helping the combustion and maintaining the flame. There is a secondary zone (free board) which burns the flue gas, utilizing the heat of the burning material before emission of the gases through the flue.
If the right kind of waste is loaded, there will be no visible smoke. The hearth is of a grated type which permits ash to fall down and be easily collected through the ash chamber.
The LD/MD/HD models are preferred by many establishments such as Space Research, Defence Organizations, Central Bank, Product label manufacturers, packaging companies, large campuses and practically every organisation that uses packaging materials.
We are happy to have these incinerators in our range, as they make every user a satisfied customer.
These are not called Incinerators but ‘trash destructors’ and rightly so.
Haat also offers shredders for these materials.
Incinerator with scrubber and 30-m chimney installed by HAAT has been working satisfactorily since June 1999 in our factory. We use it for disposing of paint sludge - Mr. Pankaj Tyagi, New Holland Tractors (India) Pvt. Ltd., Noida.
