This study aims to develop eco-friendly algae remover and heavy metal removal by utilizing the following two characteristics by-products of discarded chestnuts: (1) Polyphenols contained in chestnut by-products are effective in removing heavy metals. (2) The porous structure formed by carbonizing the outer shells of chestnuts may absorb algae. Using abandoning chestnut by-products can minimize the costs of raw material...

People die prematurely every year due to air pollution, mostly due to car traffic. Green infrastructures can act as PM sinkers, through the deposition and removal of airborne pollutants. ATMOS aimed at quantifying PM retention by trees, developing a new methodology to calculate PM retention, based on volume function and assessing the economic value of the ecosystem service provide by...

Increased urbanisation and population have led to higher medicine concentrations detected in water systems worldwide. This study investigates the effect of one of the most widely pollutant medicines (ibuprofen) on Chlorella pyrenoidosa as a model for other microalgae and higher plants. A colorimeter set to 440 nm was used to measure the effect of ibuprofen concentrations Chlorella growth over 11...

Due to global warming, droughts cause great stress to plants, slow down their growth, reduce the supply of plant foods, increase the cost to the customer. Farmers use expensive biostimulants in order to save crops during droughts. So, I decided to look for an effective alternative – calcium compounds, which are widely used in agriculture to regulate soil acidity, and...

The purpose of this research is to use civil wastewaters entering the purification plant and those coming out of it after various treatments to build a galvanic battery and produce electric current. The water sent for purification contains molecules formed by elements such as carbon, nitrogen, sulfur and phosphorus in a predominantly "reduced" state and is scarce in oxygen concentration....

Flame retardants (FRs) are often used in extinguishing forest fires. However, their ecological consequences are often overlooked. After use, FRs wash into nearby drainage basins. They contain biologically available nutrients to marine microbes and may disrupt the food web. FRs may affect relations between microbes and disrupt the system’s balance due to different absorption rates between species. These effects are...

Methane produced from animal waste impacts global warming 21 times more than CO2. Globally, around 570 million tons of methane is released and wasted annually. This energy source can be harnessed to produce renewable, sustainable energy. This experiment aimed to optimize anaerobic digestion by (i) comparing biogas production from ruminant vs. monogastric manure and (ii) observing whether adding spent mushroom...

The disposal of conventional insulation boards is proven to be very complex and expensive, and of course also harmful to the environment, people, and animals. Now with our ingredients, these problems are solved. The binder we use is 100% biological, unfortunately we cannot name the binder because of patent application reasons. Our cooperation company the KRAIBURG Austria GmbH & Co....

Despite extensive research, we still don't know everything about microplastic in the environment. That's why, when I accidentally detected microplastic in bird pellet of protected species, I decided to begin researching this topic. The main purpose of this study was to recognize the contamination of small rivers in urbanized areas of my home city and check how the microplastics are...

Water samples from different rivers in Luxembourg showed the presence of different levels of concentrations of nitrites, nitrates, and phosphates. Their effects on aquatic microorganisms were assessed by storing the water under different conditions and being filled up with various amounts of manure. Effects of the manure on aquatic organisms were observed not only by calculating their abundance but also...
