Yes, grease on the glass does not prevent it from being recycled. You just need to make sure that the bottle is empty when you put it in the recycling bin. If your bottle has metal caps, remove them and put them in the yellow recycling bin.

Glass bottles, jars and containers should be placed in the green recycling bin. All other glass items, such as mirrors, broken glasses or porcelain, should be disposed of in the regular rubbish bin, as they have a different chemical composition that resists the high temperatures at which other glass melts.

No. Only packaging (containers that temporarily store products and are mainly used to group units of a product together in order to create better conditions for distribution, transport and storage) can be placed in recycling bins. Mirrors are not packaging. Furthermore, mirrors cannot be recycled due to their composition. In order for the mirror to reflect images, it is composed of a layer of chemical elements (such as silver, aluminium or tin) that are difficult to separate from the glass, which makes it impossible to recycle mirrors. Only glass packaging, e.g. bottles, jars and pots, should be placed in the green recycling bin. The composition of packaging glass is not the same as other types of glass and therefore does not melt at the same temperature. Crockery or window glass, if placed in the recycling bin, can render an entire batch of recycled glass unusable. For this reason, light bulbs, glass or crystal cups, mirrors, medicine bottles, Pyrex, ceramic plates/cups should not be placed in the green recycling bin, but in the ordinary rubbish bin, as there is currently no way to recycle them. For further clarification on this matter, we suggest you consult the regulatory authorities: Entidade Reguladora dos Serviços de Águas e Resíduos (ERSAR) and Agência Portuguesa do Ambiente.
