Green Schools

Gonzaga College SJ is proud to be in the Green Schools Programme, where we aim to better our school by making it more environmentally friendly.

On Wednesday 22nd May 2019 we were presented with our sixth Green Flag, this one for Global Citizenship: Litter and Waste. Previous themes were Litter and Waste, Energy, Water, Travel, and Biodiversity.


As part of our work on Global Citizenship: Litter and Waste, we conducted a global awareness survey, a nationalities survey and a waste audit. We carried out litter pick ups on the school grounds and sold water bottles and travel mugs to encourage students to avoid single use plastics.


We are currently working on our seventh flag. The theme this time is Global Citizenship: Energy. 

To promote biodiversity on the school grounds we have planted two new native hedgerows and set aside wildlife areas. See 2021 photos of the wildlife areas here, 2020 photos here and 2019 photos here.

​​​Climate Action Week 2019

Thank you to Eamon Ryan TD for an inspiring talk in the school Chapel on Tuesday 15 October 2019.

On Friday, 18 October, we organised a Swap Shop, with the aim of encouraging re-use and reducing the amount of plastic and other materials we use. Boys brought in items such as books, games, and clothes and received tokens which they then used to ‘buy’ other items.  Thanks to everyone who organised and volunteered at the event, and to everyone who brought in items to swap.


Other activities during the week included a group of 2nd year students planting bulbs in the courtyard outside the library, and TY students giving presentations about climate change to all 1st year classes. We also distributed reflective schoolbag stickers from the Road Safety Authority to all 1st years to help them be visible while walking and cycling, and took delivery of bike parking for 20 more bikes from Dublin City Council.

We are also happy to announce the results of our Green Code competition. The winning English-language entry is 'Energy misused cannot be re-used' by David Egan in 1st year. Seán Radcliffe in 2nd year wins the Irish-language competition for 'Sábháil inniu, mair amárach'.

We have also continued working on previous themes. For example,

To facilitate more cycling to school, we installed new bike stands with funding from Dublin City Council. We have also participated in two 'Fridays for Future' demonstrations outside Leinster House and in the climate action demonstrations on 15 March and 20 September 2019. See here for more details.

Reports on Previous Green Schools Trips

Ringsend Water Treatment Facility

On the Thursday the 22nd of March the Gonzaga Green Schools Committee embarked on a trip to the Ringsend Water Treatment Facility. There was a total on eight committee members on the trip ranging from 1st to 4th year. We were also accompanied by Ms. S. McNamara (The College Librarian) and Ms. B. Rooney (The College Administrator).


At 10:15 we let class and departed from the school to Ringsend.  When we arrived we were given a very detailed presentation by Mr. Paddy Higgins about the history of water treatment and the history of the facility. He also explained about how water treatment works in Ringsend and then gave us a tour of the facility.


 Firstly sludge has the large objects removed such as grit and other large objects. Grease, fats and oils are also removed at this point. The solids are then separated from the liquid at this point. The solids or sludge are converted into a fertilizer by use of heat and gas. There is also a byproduct gas from this process which accounts for 40% of the facilities energy.


The water is then stored in a variety of different tanks to allow remaining smaller solids to gather at the bottom of the tanks. There is also oxygen added at a later stage to further clean it. Whilst in these tanks there are micro-organisms which eat through the bacteria in the tanks and produce the byproduct of nitrogen. When the water leaves this secondary treatment area it is clean enough to return to the sea although it is checked before it is pumped into the sea. During the bathing season of May to August there is a third form of treatment. This is exposing the water to ultraviolent light to disinfect it. The water is then sufficient to return into the sea. If the water was to be clean enough to drink it would need to go through a fourth stage of treatment as happens in London.

At the end of the process there completely clean water pumped into the sea and a byproduct of a fertilizer. There are no harmful byproducts from the sewage. The facility is very environmentally friendly and the Dublin Bay Project is one which allows for water to be treated to the maximum possible level.


In conclusion the trip was very enjoyable and insightful. At this point I would like to thank Ms. Rooney and Ms. McNamara for bringing us on the trip and Barry Mulvey for organizing it.

On Thursday the 29th of March, the members of the Green schools committee once again set forth upon a school tour. The eleven of us ventured, this time, to the vast IKEA centre. We departed at 10:15 and travelled there by coach. 

When we arrived we were met by the IKEA sustainability manager for the environmentally friendly measures taken by the Dublin branch of the company. He delivered a very explanatory presentation on the steps taken by IKEA to ensure fair trade, well-treated labourers and eco-friendliness within the organisation; this also covered details on the IKEA policies towards human rights promotion and recycling. Following this we were taken down to the workshop area of the store, where we were shown how IKEA fixed damaged products for reuse instead of disposing of them.

Once our guide had finished giving his talk about his work in the company, we were treated to a meal in their restaurant. During this time to ourselves we were able to see the measures IKEA had taken to become more efficient and environmentally friendly, first hand. We were also each offered some complimentary pencils as we left. Having finished our lunch we found our way out of the shop and back to our bus. 

In short, the trip successfully demonstrated to us the requirements of a company such as IKEA in order to improve our planets pollution levels. We were also impressed by their work in human rights. The tour was very helpful and I would like to thank both IKEA and those within the school who organised it.
