General characteristics of the wastes from the food industry

• Organic materials subject to decomposing;
• Their majority can get back to the soils with the natural cycling of biomass, where these
decompose and the organic material content builds back to the environment;
• Except the hazardous wastes of animal origin;
• Many of them has large volume and high moisture content;
• These are generated in high quantities but scattered;
• Costs of collection and transport limit frequently the range economic utilization;
• These can be perishable and in these cases their storage life is limited.


Waste treatment

• Waste treatment: technology of waste elimination, waste (re)use and waste management, covering:
• Collection of waste in the place it was generated;
• Temporary storage;
• Transport;
• Disposal in a facility created for this purpose (dumping);
• Pre-treatment and/or processing;
• And (re)use.


Waste elimination

• Rendering the waste harmless in an environmentally friendly way;
• Via chemical treatment, incineration, reuse, final, or temporary storage, or dumping;
• With or without retrieving the useful components.


Waste utilization

processing and utilizing or re-selling the waste within the given industry (reuse), or into different industries (recycling).
