Industrial waste can be similar to household waste when it consist mainly of cardboard, paper, plastics, wood, metals, glass, textiles and more. Not all hazardous wastes are collected, disposed of or stored under optimal conditions. For instance, there is toxic waste in dispersed quantities, which is waste generated by the activities of small industrial units.
Fermentable waste is biodegradable waste, that is decomposing under the action of aerobic or anaerobic microorganisms (bacteria, moulds). Garbage contains a large part of fermentable matter, which is called the fermentable fraction of household waste. This can be extremely reduced by selective sorting.
Toxicity
Waste can be toxic in a number of ways: either directly or as a result of a physical or chemical reaction with other substances with which they come in contact at some point during their disposal, treatment or storage. The waste can give rise to poisoning.
Some waste is potentially dangerous because it contain asbestos, ceramic fibers, ashes, unburned particles and more. Dust can cause chronic respiratory diseases, inflammatory manifestations and allergies. In addition, dust, especially those derived from fermentable materials are perfectly capable of transporting, sometimes very far, bacteria or various other pathogenic viral or fungal microorganisms.
The other waste substances are mainly metals: cadmium, mercury, lead, thallium, arsenic, boron, aluminium, chromium, manganese, nickel, cobalt, vanadium and zinc. Some of the gases found around incineration plants include sulphur dioxide and sulphur trioxide, carbon monoxide, nitrogen oxides, hydrogen chloride, hydrogen fluoride, dioxins and furans.
The list also includes various volatile organic compounds mainly from incomplete combustions (cyclic hydrocarbons, aromatics, alkanes, alkenes, aldehydes, ketones, acids, PAHs, etc.), phenols and cyanides.
Exposure to a phenomenal amount of substances suspected to be reprotoxic is constant around the waste. These are primarily pesticides, but also synthetic hormones and many other endocrine disruptors.
Plastic disposal
Plastics are found everywhere. This is why the recycling of these materials is subject to specific regulatory requirements. In construction and industrial sectors, plastics are used for flexible or rigid pipes, fluid sleeves, ventilation ducts, grilles and shutters. In some cases, they are used to manufacture partitions, walls and ceilings, floor or wall coverings.
Today, industrial waste Redcliffe sorts a number of waste products, including plastic packaging. PVC is incompatible with PET recycling for a melting point: 170 ° C for PVC and 270 ° C for PET. Two or three PVC bottles in a tonne of PET is enough to colour all the mass of PET, which makes it unusable.
It is more or less the same for various other categories of plastics for which there is little knowledge on how to revalue.
