Kiếm bộn tiền nhờ... phân voi
ông ty Maximus tại quốc đảo Sri Lanka đang hốt bạc nhờ sáng kiến sản xuất các tấm thiệp từ phân voi. Voi là một trong những nguồn tài nguyên dồi dào nhất ở Sri Lanka. Theo Tổng giám đốc Thusitha Ramsinghe của Maximus nhận xét rằng quá trình nghiền bột diễn ra ngay trong dạ dày của voi: “Chúng tôi nhận ra là phân voi có một lượng xenlulo rất cao. Vì vậy, thử dùng phân voi để làm giấy cũng tự nhiên thôi”.
