The main function of controlled landfills is the disposal of complex wastes under such conditions that possible negative effects on the environment are minimized or eliminated. Although the substances dumped cannot be used, the degradation of organic matter is achieved, which makes possible the use of the gases generated and the future reuse of the area, mainly as a recreational area.
The characteristics of landfills depend on the methods of operation and management of the landfill, as well as the general characteristics (waterways, bodies of water and agricultural or urban areas; existence of groundwater or natural reserves, geological and hydrogeological conditions; risks of flooding, subsidence, earth movements or avalanches; protection of the cultural heritage of the area where they are to be located) and consider the distances between the landfill boundary and residential and recreational areas.
To prepare the landfill area it is necessary to carry out a series of operations to leave the land in a condition to receive the waste. Basically, these operations and their characteristics are as follows:
Cleaning and disinfection protocol for facilities
Organic fertilizer: product whose main function is to provide nutrients for plants, which come from carbonaceous materials of animal or vegetable origin, whose list is included in group 2 of the annex of the Royal Decree 824/2005, of July 8, on fertilizer products. (RD 824/2005, fertilizer products)
Industrial oils: Lubricating oils of mineral, synthetic or assimilated base of animal origin, in particular oils for combustion engines, transmission systems, lubricants, turbines and hydraulic systems. The products and preparations listed in Annex III are included in this definition.
Any other products intended for consumption, offered for sale or used in the uses that are proper to the products and preparations listed in the previous epigraph, in accordance with the criteria established in the combined nomenclature detailed in Annex III. (RD 679/2006, Used industrial oils)

Thursday, 02/Aug/2018Food hygieneCleaning and disinfection are two distinct processes, key in the food industry, which in most cases are performed separately. The purpose of cleaning is to remove dirt and organic matter from equipment and surfaces so that effective disinfection can subsequently be performed to remove microorganisms to levels adequate to ensure food safety.
It is important to understand that cleaning and disinfection operations should be considered as a step in the food production process, and not as a complementary activity. Also, the personnel responsible for cleaning and disinfection should have a broad knowledge of the importance of contamination, the risks involved and the cleaning and disinfection technologies to be used.
Cleaning and disinfection are distinct and complementary processes. The presence of organic matter significantly reduces the action of disinfectants. Therefore, before applying a disinfectant solution, surfaces must be properly cleaned with detergents to allow the disinfectant to come into direct contact with the specific pathogenic microorganisms.
Integrated Waste Management or simply Waste Management is the name given to the process that encompasses the activities necessary to take care of a waste, as a material that loses its usefulness after having fulfilled its mission or service for which it was produced. In other words, the concept of waste is used as a synonym for garbage, i.e., it is all waste of that which man has produced. There are different types of solid waste.
There are different types of solid waste, such as those generated in cities (domestic, residential, institutional or commercial), agricultural or industrial (productive sectors, industries, industrial parks, sanitary facilities, etc.). The main waste is produced by human activity.
Hazardous waste is considered to be industrial or commercial waste that, because of its toxic or dangerous characteristics due to a high concentration of risk, requires specific treatment and periodic monitoring of potential harmful effects.
The first step towards an organized management of municipal solid waste was taken in the United States at the beginning of the 20th century. 2] Up to that time, and depending on the location, waste was dumped on the ground – buried or in the open air -, discharged into bodies of water, incinerated or, in the case of food waste, fed to pigs.
