Tóm tắt

Các quan chức y tế tại Ensenada thiếu thông tin thích hợp về quản lý bền vững chất thải rắn, giống như các quan chức y tế tại các nước đang phát triển khác. Mục tiêu của nghiên cứu này là: (a) định lượng và phân tích các chất thải rắn hộ gia đình phát sinh tại thành phố Ensenada, Mexico; và (b) dự đoán sản xuất biogas và ước tính năng lượng điện phát sinh. Nghiên cứu phân loại được thực hiện thông qua phân tầng xã hội kinh tế trong hai thời kỳ mùa vụ, và dự đoán biogas cùng năng lượng điện được thực hiện bằng cách sử dụng mô hình biogas Mexico phiên bản 2.0. Mức độ phát sinh chất thải rắn bình quân đầu người là 0.779 ± 0.019 kg/người/ngày trong khoảng tin cậy 98%. Thành phần chất thải chủ yếu bao gồm thức ăn thừa với 36.25%, tiếp theo là giấy và bìa ở mức 21.85%, nhựa đạt 12.30%, tã dùng một lần là 6.26% và vải vóc là 6.28%. Dự báo công suất phát điện tối đa dự kiến sẽ đạt 1.90 MW trong năm 2019. Chất thải phát sinh có thể được sử dụng như một trung gian trong nhiều quy trình khác nhau như tái chế (41.04%) và thu hồi năng lượng (46.63%). Năng lượng điện mà có thể thu được từ biogas được sản xuất tại bãi rác Ensenada sẽ cung cấp khoảng 60% năng lượng cần thiết cho việc chiếu sáng đường phố.
