Topic 1: Reduce (River Degradation)

1.1 - Reducing Plastic

We choose the subject “Reducing plastic” because it’s a major problem in modern society and it has a huge impact on our ecosystem and marine life and livestock.
After we chose the subject, we brainstormed and found the subtopics and the connections, we worked for one hour and a half and later on developed the mind map and took pictures and videos to document our work.
Microplastics are everywhere and get into every bit and corner, in food in water and animals.
So of course, we want to eliminate this problem as soon as possible so we took a look around and found the connections and causes that lead to this problem.
In conclusion reducing plastic will lead to a better and greener future.

1.2 - Pollution effects on river ecosystem

The aim of this report is to describe the events during day 2 of the LTTA in Kaunas. The students were divided in four groups and our main task was to describe the consequences of water pollution on fluvial life.

In order to present all the information clearly, the students used an editing platform “Canva” to create colorful mindmaps. The mindmap was created by using many colors, descriptive imagery and appropriate information. They researched all the information online and used their knowledge from older experiences and also asked professionals in different fields for their opinions. At first, some guidance by the mentors was needed, but as time went on, they managed to get a hold of the pace of the work and they were beginning to work as a team.

Two students from our group presented our works. They mentioned the impact that pesticides, acids and other harmful substances have on our planet and human lives. As a conclusion, they thought up a statement and encouraged the listeners to make a change.

As far as reaching the day’s target is concerned, the students successfully presented their topics. They were loud and clear, learnt new knowledge and developed their teamwork skills.

Our speech:

The planet keeps nudging us with increasingly extreme droughts, reminding us that water is life. It is an essential resource upon which all living beings depend and it is crucial to all social and economic development, as well as energy production and adaptation to climate change. Nevertheless, we are now facing a gigantic challenge. To make change for the better its most important to understand how it affects the planet, more specifically the river ecosystem.


  1. Industries that are unable to properly dispose of their waste and end up draining it into fresh water, which enters rivers, canals and finally the sea. We are talking above all about the chemical industries that produce nitric acid, soda, phosphoric acid, ammonia, sulfuric acid, hydrochloric acid and numerous other polluting substances.
  2. Agricultural pollution, what I mean is uncontrolled, immeasurable use of fertilizers, herbicides, pesticides and pesticides in large quantities.
  3. Urban pollution encompasses all the water that derives from the discharges of our homes, our offices and other structures which, if not properly treated and purified, contribute to the pollution of our waters.


1.Destruction of biodiversity; Water pollution depletes aquatic ecosystems and triggers unbridled proliferation in lakes.

  1. Contamination of the food chain. Fishing in polluted waters and the use of waste water 2. for livestock farming and agriculture can introduce toxins into foods which are harmful to our health when eaten.
  2. Infant mortality. According to our recourses diarrhoeal diseases linked to lack of hygiene cause the death of about 1,000 children a day worldwide.


In today’s world, we all live to find solutions to our problems. Solving problems means making choices. Typically, when children tackle problems on their own, or in a group, they become resilient. They learn to look at challenges from a fresh perspective. So here right now we are working towards telling you the SOLUTIONS we have come up with.

* Use biodegradable materials, limit the use of plastic, try to contain waste production as much as possible. Help the planet

 * Use natural detergents, such as those based on lemon or white vinegar, so as to avoid chemical detergents. Save the river ecosystem.

 * Never throw solid objects or paints, solvents, medicines down the drain. Protect everything that can’t protect themselves.

 * If you have a garden, use only natural fertilizers and herbicides.  Synthetic products are a real problem for groundwater. Be a part of change.


to start off FISH SPECIES, one of the easiest to describe is salmon. Pesticides and petroleum-derived compounds suppress the immune system, rendering salmon weaker to pathogens that cause lethal diseases. Petroleum-derived compounds are also known to depress growth rate of juvenile salmon, which can affect their survival.


The river also has plants that are very important to the system. algae masses are a big part of the ecosystem that we cannot miss out on we all need to remind ourselves that even though we’re talking about pollution, some organisms need to be there for it to stay alive for example.

1.3 - How to reduce industries’ pollution in rivers

The reason we chose the topic “How to reduce industries’ pollution in rivers” is because industry is the most common cause of pollution in rivers. We are from different countries, but this problem is something that occurs in all of them.

For the first step we divided roles and started to work on our maps. Throughout the process we took some photos of our work and teammates. We also wrote a report; first we brainstormed, made a concept for the presentation and turned it into a text. Four members of our team worked together on the mind map searching the internet for information and pictures, and next they divided problems and solutions.

With this presentation we wanted to explain how dangerous problems of industries are and how much they affect rivers. We also wanted to provide some solutions that can fix it. It’s important to talk about these issues and to raise awareness.

In the words of famous political activist Bobby Seale: “The only solution to pollution is a people’s humane revolution”

Topic 2: Reuse (Biorefineries' Principles)

2.1 - Biorefinery of lignocellulose biomass

The reason why we chose this topic is because we think it is very important to find new biorefinery methods which are more environmentally friendly, using lignocellulose biomass. For the first step we have split up into three categories, the creative: Gabrjel, Nino, Leon and Alexandra; the reporters: Paolo, Giovanna, Emily and Ema; and the speakers: Haroldas and Bianca. Using the Internet, we researched all the information and reported it on canva, then, we took some photos and videos. We have divided the topic into various sections, such as goals, prons and cons etc. Biorefineries produce fuels using organic matter like waste, lignocellulose, algae and agriculture residues. What is Lignocellulose biomass? It is an abundant renewable resource from plants composed of polysaccharides and aromatic polymers. It is the most abundant and bio-renewable biomass on Earth. Studies have proved that this biomass holds enormous potential for sustainable manufacturing of chemicals and fuels. To finish off:

2.2 - Biorefinery of organic waste

The topic our team chose was biorefinery of waste, or to be more specific, organic waste. The topic seemed versatile and relevant since humans create organic waste quite easily therefore it is often encountered. Our team’s work started with choosing the right colour palette that would reflect the colours of nature and organic materials that are related to our topic. Then followed the process of deciding what type of subtopics should be in the mind map so the creative team was given a helping hand from our team’s speakers and other members to decide together on the structure of the map.

The visuals of the map start with the middle section, which is waste, and four subtopics, three of them being steps that are made to process waste and the last one showing the problematic side of waste and its biorefinery: 

  • First of the four mentioned subtopics is process (top right section of the map). In other words, the way waste needs to be processed before following the next steps towards biorefinery. Ways of processing presented on the mind map are collecting, chopping waste so that it could be easier to convert it, and cleaning – drying and washing.
  • Second step is conversion (bottom left side of the mind map). Conversion includes fermentation processes when waste is converted into biofuels like ethanol, butanol. Also, thermochemical conversion – decomposition of organic matter for the production of biofuels like biochar and syngas.
  • Third step is on top left section of the mind map. Separation is needed because the converted waste produces not a pure product but a mix of different ones, so it needs to go through distillation when water is removed from biofuels or upgrade like dehydration or blending when biofuels are mixed with gasoline.
  • Last section is problems (bottom right section of the mind map). Odour, toxic waste and limited disposability options when not all waste can be used for processing or when there is too much waste to be able to process it are discussed.

The mind map was presented by two of our members who neatly talked about the topic, keeping the information more general and well structured, describing everything in a simple and comprehensive way, without getting into too intricate details.

2.3 - Biorefinery of algal biomasses

For today’s mind map, we chose the Algae topic. Our group chose this topic because we think that algae are crucial for human population both because of oxygen that they produce and fuels that we get from them through biorefineries.

For the first step we divided roles and started to work on our map. Throughout the process we took some photos of our work and teammates. We also wrote a report; first we brainstormed, then we came up with a few ideas for the presentation and made a text out of it. Four members of the team worked together on the mind map searching the internet for information and pictures, and next, they divided problems and solutions.

With this presentation, we wanted to explain how algae biorefineries work, the pros and cons of the process and how biorefineries can help us and the environment.

2.4 - Biorefinery of agricultural residues

Our team has chosen the subject- Agricultural residues. Working as a team, everyone has a responsibility. 4 people are working on the MindMap itself, 3 are filming the process, and 2 will present. The task at hand is important to our education. To remember what you learn, you can try different strategies. Here, with us we’re talking, writing down, scribbling our thoughts down and hoping for the best. The time limit, pressure can affect us and our actions. Our arguments contain:


It is so easy to overbuy products. Especially, when you own a farm and are not sure the exact amount you may need. There are also times that you may think it is better to buy more upfront than come back to the store more often. 


Farmers can reduce waste by composting many of their items. They are good for the soil and help the plants to grow. This is a great environmentally friendly option that farmers can take advantage of. Some of the many things that you should compost are:

  • Animal Waste
  • Plants
  • Weeds and Grass Cuttings
  • Leaves, Straw, and Hay
  • And others….  

Also, the agricultural waste itself:

  • Crop residue waste
  • Livestock waste
  • Agro-industrial waste
  • Aqua-cultural waste.

Topic 3: Recycle (Water)

3.1 - Municipal wastewater /sewage composition

Wastewater is water generated after the use of freshwater, raw water, drinking water or saline water in a variety of deliberate applications or processes. [2]

Sewage (or domestic sewage, domestic wastewater, municipal wastewater) is a type of wastewater that is produced by a community of people. [1]

We think it is important to talk about this topic because sewage which is not properly treated and disposed, can have negative impacts on the environment and public health. Also, it is important to talk about municipal wastewater because it can contain microorganisms and it can also have bad influence for public health and the environment. Microorganisms can impact the quality of water if they are not properly treated. Sources from which municipal wastewater came from are: industrial wastewater, point sources, dispersed sources and municipal wastewater. Pollutants that are in municipal wastewater are: pathogens (bacteria, viruses, parasites), non-biodegradable compounds (metals, plastic, glass), biodegradable compounds (paper waste, green waste, food waste), nutrients (nitrogen, phosphorous) and solid particles.

3.2 - Municipal wastewater/sewage treatment processes

Today Lidia assigned all the groups a specific topic, our topic was sewage treatment.

Firstly, we brainstormed, and we created the mind map, while doing the mind map the journalists took videos and pictures and then we practiced our presentation.

Sewage treatment can be divided in three stages or treatments:

  • the first treatment consists of sorting in a basin sewage, so the solids can separate from the lighter substances and liquids and they can be sent to the second treatment.
  • the second treatment removes dissolved biological matter; thus, treatment uses aerobic bacteria.
  • the third and last treatment is uses to further clean water when it’s being released into a different ecosystem.

3.3 - Recycled water re-use

For today’s mind map, organizer gave us our topic” recycled water re-use”. For the first step we divided roles and started to work on our map. First, we shared our ideas on how our mind map should look like and four designers Rokas, Ema, Emily and Leon got inspired and started to work. They searched for information on the internet and started to add pictures. In mind map making process three journalists took some photos of teammates and them working. Two speakers Sonia and Nino worked together and wrote a script about what they would talk about. We wanted to show ways how recycled sewage can be used and divided, our map is a perfect example of this topic.
