What is Composting? 

Composting is a biological process in which micro-organisms transform organic matter, such as manure, leaves, paper and food scraps, into a material similar to soil which is called compost.
"Home composting saves transport and waste disposal costs and gives a proper final destination to the type of waste involved."

What shall I do with used cooking oils?

Unfortunately, most of the times used cooking oils - UCO - (sunflower, soya, olive oil) are poured down the sink.
This is a voluntary or involuntary mistake which has environmental impact!
Separating used cooking oils has many environmental, social and economic advantages, as it will allow a proper final handling of this type of waste. Some of the most important advantages are the avoidance of water contamination (one litre of cooking oil contaminates about 1 million litres of water, which is the average amount of water a person consumes in 14 years!), the conservation of pipes, the proper operation of Waste Water Treatment Plants and the adoption of an exemplary attitude of a citizen who is aware of the current problems that influence the future of the planet and the next generations.
The sorted UCO are disposed of in specific containers ("oleões"), collected and sent to recycling, to be used namely for the production of natural soap or biodiesel (biofuel).
These specific containers for UCO exist currently in all associated municipalities, within LIPOR's area of intervention. Find your nearest container for UCO disposal
If you can't use one of these collection points, store the cooking oils in plastic bottles or absorb the oil with used paper napkins and place them in the unsorted waste container. This way you won't damage or contaminate watercourses! 

I want to buy a new refrigerator. What should I do with the used one? 

When you decide to dispose of an appliance, you can choose one of three options: exchange the used appliance for a new one, use a selective collection circuit or donate it. If the appliance still works, many institutions would be happy to receive it.
When you buy a new electrical appliance (toaster, microwave, television, washing machine, etc.) you can hand over the used one to the store, for free, as long as it is the same type of appliance, with the same function. This also applies to home delivery services.
You can also contact your City Council and ask for the collection of large domestic items or dispose of them in drop-off sites or any other authorised waste reception centres.
The appliances collected are then sent to the proper facilities to be (totally or partially) reused or dismantled and recycled.

What should I do with fluorescent lamps? 

Don't throw these lamps away with unsorted waste and, more importantly, don't place them in the green container (for glass). Fluorescent or discharge lamps cannot be disposed of with unsorted waste, because they contain hazardous substances that should be collected separately.
When these bulbs burn out, you can hand them over, for free, to the establishment where you're going to buy the new lamp. You can also dispose of them in collection centres for waste electrical and electronic equipment or drop-off sites that receive this type of waste.
Economic lamps can be placed together with fluorescent lamps. 

What are large domestic items? 

Large domestic items include household appliances, electronic equipment, old furniture and other types of waste that cannot be disposed of in eco-containers or the unsorted waste container, due to their characteristics or dimensions. First of all, check if they are still fit for use and can be donated to charitable institutions.
Some City and Parish Councils collect large items placed near waste containers or provide door-to-door collection. Contact the responsible authority to schedule the date and time of collection. Thus you can avoid that large items remain in the street for a long period of time. You can also take them to the nearest drop-off site. 

What should I do with filament lamps?

Conventional filament lamps can be disposed of together with unsorted waste. Low voltage lamps should be placed in drop-off sites or specific collection centres for WEEE (Waste Electrical and Electronic Equipment). 


What is waste?

What is a Landfill? 

A Landfill consists of an area of land appropriately prepared for waste confinement (waterproof and with collection, treatment and monitoring systems for liquid and gaseous effluents), where waste is disposed of in an organised way and covered with soil or a similar material.


What are Leachates?

Liquid effluents that flow through the Municipal Waste in landfills and which result from water contained in waste itself, rainwater that falls on waste and infiltration of underground waters.


What is Municipal Solid Waste? 

Waste from houses and other similar waste, in its nature or composition, in solid form.
