Waste management

Waste Production Indicators

As a major producer of waste similar to Urban Solid Waste (USW), Ciências annually produces around 250 tons of unsorted waste and 130 tons of recyclable waste. Per capita, they correspond annually to approximately 40 kg of unsorted waste, 5 kg of paper, 3 kg of glass, 2 kg of packaging and 8 kg of organic waste, integrated in CML's collection circuits.

Ciências has been making an effort to recycle its recyclable waste, increasing and diversifying internal recovery circuits, through the establishment of protocols with licensed operators or, in the case of organic waste, through the development of composting processes (garden waste ) and vermicomposting (food waste).

The graph shows the evolution of the production of recyclable waste, forwarded through dedicated circuits to licensed operator, by type of waste, as well as the investment made by Ciências in increasing the number of recycling rows from 6 rows in 2015 to 16 in 2020.

In general terms, it appears that the amount of waste has increased over the years, which is due not to an overall increase in waste produced in Ciências, but to the increase in the fraction of waste that can be sent to licensed recycling operators and/or enhancement and for composting and vermicomposting processes.

Dedicated recycling circuits

It has been possible to increase the recycling rate by placing outside ecopontos in strategic areas of the campus and also by placing small ecopontos inside buildings.

Blue Ecoponto - paper and cardboard 

  • Cardboard boxes, magazines and newspapers, writing and printing paper
  • Do not place plastic bags, polystyrene, dirty paper, silver paper, vegetable paper, paper with plastic, waxed paper, stickers 

Green Ecoponto - glass packaging

  • Bottles, jars
  • Do not place empty bottles of chemical reagents, dishes and ceramics, flat glass and glazing, crystals and mirrors, lamps

Yellow Ecoponto - plastic and metal packaging

  • Plastic packaging, beverage cartons, cans, plastic bags
  • Do not place empty packages of chemical reagents, paper and cardboard, household appliances

Ink cartridges and toners

Boxes for collecting used inkjet and toner cartridges in the following locations:

  • C1 Building – Near IT Services
  • C2 Building – 2nd Floor east, near women's toilet
  • C8 Building – 6th Floor, near the DQB room 8.6.33
  • TecLabs Building – Floor 0

Fluorescent and discharge lamps

Under the nascent bridge between the C1 and C8 buildings, there is a container from AMB3E for placing fluorescent and discharge lamps. If you also have lamps in your home that you want to dispose of, you can bring them and deposit them in the container.

Used oils

The Faculty periodically routes waste mineral waste oils (including pump oils). Users must deliver to the waste collection point outside the 1st floor of Building C1 on Thursdays between 10.45 am and 11.15 am.

Batteries and accumulators

Boxes for the collection of batteries and accumulators in the following locations:

  • C1 Building – 2nd floor, west atrium
  • C2 Building – 2nd floor, east atrium
  • C4 Building – G3S, room 4.1.26
  • C5 Building – 2nd floor, near the Surveillance Central
  • C8 Building – 2nd floor, administrative support
  • Tec Labs Building – Floor 0
  • MARE Building – Stairs between 1st floor and floor 0

Users can also request the collection of batteries and accumulators by e-mail.

Waste from electrical and electronic equipment

The Faculty periodically routes waste electrical and electronic equipment (WEEE). Users can request the collection of WEEE by e-mail.

 

Composting and vermicomposting

FCUL Composting
One year: 40m3 of waste and 11,2 tons of compost

How is Ciências improving restaurant food waste management?


"Food waste stopped going to waste, instead, it was diverted by me and a faculty employee to PermaLab. Here, they were placed in boxes specially made to speed up composting that reaches high temperatures, and then be placed in different boxes, where hungry worms could feed on the material. The resulting product is a high-quality vermicompost, ready to be used to produce food, which can be eaten again. This is how we close the organic cycle."

Annual compost production

Average values ​​for 2018, 2019 and 2020:

  • 28 tons of processed garden waste
  • 11.2 tons of fine compost produced

 

Annual vermicompost production

Average values ​​for 2018 and 2019 (2020 was not considered due to the closure of bars and restrictions associated with the COVID-19 pandemic):

  • 1.3 m3 of processed kitchen / bar waste
  • 0.9 tons of vermicompost produced

 

Hazardous Waste

Ciências ULisboa takes an active role in preserving a healthy environment through the application of good environmental practices, the transfer of knowledge in this area and the awareness of employees, students and visitors. A correct waste management is, besides a legal imposition, an obligation of a Science School.
