How hazardous waste is disposed?

Types of hazardous waste

Identify the wastes produced in the laboratory activity and request the most appropriate container for each type depending on the state (liquid, solid or gel), the speed of its generation and the space available in the laboratory.

Laboratory waste is classified into different categories according to its nature, hazardousness and final destination. Please classify each waste you generate into one of the groups in the following table (Consult SEPA for any doubt or clarification about the classification of waste). Download the corresponding label, filling in the blanks (substance/s contained in the container, applicant’s data). They are in fillable pdf format. For your convenience, the “applicant’s data” fields are autocopied on all labels once they have been written on any of them. Attach them to the container before you start filling it, that way everyone in your group will know what is being deposited in it.

VERY IMPORTANT: the labels include a hazard pictogram that must be printed in color, in accordance with the REACH Regulation (Registration, Evaluation, Authorization and Restriction of Chemicals), and preferably on four-label self-adhesive paper (If you do not have a color printer, print in black and white and color the border of the hazard pictogram with a red marker pen).

Hazardous wastes are those that contain in their composition one or more substances that give them dangerous characteristics, in such quantities or concentrations that they represent a risk to human health, natural resources or the environment. Containers and containers that have contained these substances are also considered hazardous waste.

If the composition of the waste is not known, the determination of its hazardous characteristics must be carried out by testing. The test methods to be applied are described in Annex V of Directive 67/548/EEC and in other relevant notes of the European Committee for Standardization (CEN).

The shipment of waste begins once the producer has the Acceptance Document from the Manager, provided that the competent authority has been notified 10 days in advance.

In the Community of Madrid, four types of documents are used in the shipment of hazardous waste, three of them regulated at the national level (waste acceptance document-notification of shipment and DCS) and one of them at the regional level.

There are several types of hazardous waste treatment. The best is always to reduce the amount of waste at the source, or even to recycle materials that can be reused productively. However, these measures do not solve the problem of disposing of these wastes.

Some of the chemical treatments are ion exchange, oxidation and reduction, chemical precipitation and neutralization. This method is used to transform hazardous wastes into non-toxic gases by modifying their chemical properties.

For example, cyanide can go through an oxidation process making this poisonous waste a non-toxic product. Another chemical process would be water separation, which allows water to be extracted from some organic wastes and then disposed of through incineration.

Hazardous wastes in Mexico are generated from a wide range of industrial, agricultural and domestic activities. Industrial processes generate a variety of wastes with solid, pasty, liquid or gaseous nature, which may have some of the following characteristics: corrosive, reactive, explosive, toxic, and may present risks to human health and the environment, also, there are other sources that generate hazardous waste, such as hospitals, commerce and mining.

The risks to the environment and health caused by hazardous waste are a focus of attention, not only in Mexico, but also worldwide, which has led to the creation of regulatory provisions (laws, regulations and standards) that establish guidelines to be avoided and measures to be followed to achieve safe management in order to prevent risks, The contamination of hazardous bodies of water (mainly groundwater) caused by the improper disposal of hazardous waste has led Mexico to give high priority to hazardous waste management. Hazardous waste management includes the processes of minimization, recycling, collection, storage, treatment, transportation and disposal. Currently, industrialized countries tend to promote the minimization and recycling of hazardous waste as the option from an environmental point of view.
