Achieving sustainability and resilience depends on the conciliation of environmental, social, and economic issues integrated into a long-term perspective to ensure communities flourish. Many nations are transitioning toward both objectives, while at the same time addressing structural concerns that have not allowed them to look after the environment in the past. Chile is one of these nations dealing with such challenges within a particular administrative context, an increasing environmental awareness, and a set of unique and complex geophysical boundaries that impose a plethora of hazards for cities, ecosystems, and human health.

However, poor contact between biomass, especially the biomass pellet, and hydroxide during the slow heating process, as well as low reaction temperatures, become key factors limiting the hydrogen production. To address these challenges, fast pyrolysis of the algae pellet in molten NaOH-NaCO was conducted at 550, 650, and 750 °C.

- This study investigates the nitrogen-containing components (NCCs) in pyrolytic bio-oil derived from three types of algae, focusing on their composition, particularly in heavy NCCs with molecular weights of 200 Da and above.
- Using advanced mass spectrometry techniques, it was found that most heavy NCCs have molecular weights mainly between 200-400 Da, with nitrogen solutions comprising over 60% in samples rich in lipids and proteins, and different nitrogen compositions in carbohydrate-rich samples.
- As the pyrolysis temperature increases, NCCs become more aromatic and lose oxygen, while heavier NCCs decompose into lighter compounds with more nitrogen; some strategies for enhancing high-quality bio-oil production from NCCs
