Green Algae

Green Algae

Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...

Area of Science:

Green Chemistry
Waste Management
Sustainable Materials

Background:

Portugal generates significant waste from used cooking oil and almond shell residues annually.
High citrus fruit consumption, particularly oranges, results in substantial amounts of peel waste.
Diversifying waste reuse is crucial for transforming waste into valuable raw materials.

Purpose of the Study:

To explore the feasibility of manufacturing soap using waste materials: almond shells, orange peel, and used cooking oil.
To assess the potential of this process for environmental education and community-based ecological projects.
To evaluate the acceptance of the final soap product.

Main Methods:

Processing and grinding almond shells.
Treating used cooking oil.
Processing orange peels and extracting limonene.
Formulating and producing soap.
Conducting an acceptance study of the manufactured soap.

Main Results:

The study successfully produced soap from the selected waste materials.
Results indicated a high potential for the concept in environmental education and practical classes.
The process showed utility in waste management and supporting ecological community projects.

Conclusions:

The reuse of almond shells, orange peel, and used cooking oil is a viable green approach for soap manufacturing.
This initiative holds significant value for waste reduction and resource recovery.
The project can be effectively integrated into environmental education programs and community-driven sustainability initiatives.
