- Separated utilizable solid waste (Desecho sólido aprovechable separado): Utilizable solid waste that is previously separated into different packaging or containers, a task carried out at the source or at the collection center (centro de acopio). This includes various materials that are utilizable such as: glass, paper, cardboard, plastics, aluminum cans, biodegradable waste.
- Biodegradable solid waste (Desechos sólidos biodegradables): Solid waste that, when subjected to biotechnological processes, can be biodegraded within a period of no less than 6 months.
- Recalcitrant biodegradable solid waste (Desechos sólidos biodegradable recalcitrantes): Solid waste that, when subjected to biotechnological processes, can be biodegraded within a period of less than 6 months.
- Commercial solid waste (Desecho sólido comercial): Solid waste generated in commercial mercantile establishments.
- Everyday solid waste (Desecho sólido cotidiano): Commercial, household, and industrial waste collected routinely by the collection service. Non-everyday waste is excluded from this category.
- Household solid waste (Desecho sólido domiciliar): Solid waste generated in dwelling houses as a product of everyday family activities.
- Hospital solid waste (Desechos sólidos hospitalarios): Solid waste generated in hospitals, medical offices, dental offices, microbiological analysis laboratories, veterinary clinics, and offices.
- Industrial solid waste (Desecho sólido industrial): Solid waste generated as a consequence of industrial and manufacturing processes.
- Institutional solid waste (Desecho sólido institucional): Solid waste generated in public or private institutions, excluding hospitals and air terminals.
- Non-utilizable solid waste (Desecho sólido no aprovechable): Solid waste that socially lacks use value. This term is equivalent to garbage (basura).
- Non-everyday solid waste (Desechos sólidos no-cotidianos): Household or commercial solid waste that is not generated with everyday frequency or that, due to its size or weight, clearly exceeds typical family solid waste. This category includes non-traditional household garbage (basura) and solid waste from green areas or gardens of urban properties in the canton.
- Primary delivery of solid waste (Entrega primaria de desechos sólidos): Action by which the waste generator, after primary separation and storage, places the adequately packaged solid waste in such a way that waste collection can be carried out without difficulty.
- Delivery of waste (Entrega de desechos): This delivery refers to the act of delivering waste at the compost plant (planta de compostaje), the collection center (centro de acopio), or the technical deposit.
- Avoidance of solid waste (Evitación de desechos sólidos): Measures aimed at avoiding the generation of solid waste; these can be taken from the design stage of goods, either by avoiding the incorporation of dispensable parts, using materials and systems that provide a longer useful life, or facilitating the reuse and recycling of the product or its parts.
- Fermentation of biodegradable waste (Fermentación de desechos biodegradables): This designation is given to the process of biodegradation in the absence of oxygen (anaerobic) with optional capture of biogas and its incineration. During the process, bad odors are not permitted to cause nuisance to people or to cause a proliferation of insects or other pests. The biodegradation products must be innocuous for plants and biologically stabilized.
- Generators of solid waste (Generadores de desechos sólidos): Any natural or legal person that generates any type of solid waste.
- Solid waste management (Gestión de desechos sólidos): Set of measures at the family, institutional, or industrial level to avoid, store, collect, and utilize solid waste with the objective of minimizing waste generation, maximizing its utilization, reducing management costs, minimizing the amount of garbage (basura), as well as avoiding nuisances and damages to the well-being of people or the environment.

- Collection of solid waste (Recolección de desechos sólidos): Service of transporting solid waste between primary or intermediate storage and compost plants (plantas de compostaje) or collection centers (centros de acopio) or utilization industries or the final disposal of non-utilizable solid waste in technical deposits.
- Complete separation of solid waste (Separación completa de desechos sólidos): Action of adequately separating and packaging traditional solid waste into its main utilizable components, namely: paper, glass, plastic, cardboard, aluminum cans, biodegradable waste, non-utilizable waste or garbage (basura), and others that technology makes possible to utilize in the future.
- Complete separation of solid waste at the source or primary separation (Separación completa de desechos sólidos en la fuente o primaria): Action of adequately separating and packaging traditional solid waste into its main utilizable components: paper, cardboard and derivatives, glass, plastics, aluminum cans, biodegradable waste, non-utilizable waste or garbage (basura), and others that technology makes possible to utilize in the future.
