<p style="text-align: justify;">Tóc sở hữu đặc tính đáng kinh ngạc khi có khả năng hấp thu lượng dầu gấp tới 5 lần khối lượng của chính nó. Dựa trên nguyên lý này, các nhà nghiên cứu đã nhét đầy tóc vào bên trong lưới lọc rồi gắn trực tiếp lên hệ thống rào chắn rác nổi trên mặt nước. Khi dòng nước lẫn dầu chảy qua, cấu trúc của tóc sẽ giữ lại toàn bộ vệt dầu loang và chỉ cho nước sạch đi qua.</p>

<p style="text-align: justify;">Bà Mariana Robrahn - Chủ tịch Tổ chức Fiotrar, chia sẻ: “Mỗi gram tóc có tiềm năng hấp thu 5 gram dầu. Đó chính là nguyên lý hoạt động cốt lõi của hệ thống phao chắn này”.</p>

Nhà hóa học Caroline Carvalho cho biết thêm: “Bộ lưới lọc này có thể ở trên biển tới 4 tháng, giúp ngăn ô nhiễm từ tàu thuyền, xả thải trái phép và nhiều nguồn ô nhiễm khác”.</p>
