- 确定在牛肉行业改善管理的领域.
主要方法:
- 材料流量分析 (MFA) 以跟踪的输入,输出和转换.
- 在不同阶段计算利用效率 (NUE).
- 评估级联指标 (NCI) 来测量积.
主要成果:
- 输入量增加了8.47%,而牛肉产量增加了7.29%.
- 牛肉出口增长了86.03%,但人均消费略有下降.
- 利用效率 (NUE) 在屠宰中最高 (90%) 在消费中最低 (29-34%).
- 食品废弃物和人类便中的气损失增加.
- 级联指标 (NCI) 范围在77-82%之间,表明积累很大.
结论:
- 有机会提高的使用效率,特别是通过减少消费者级食品浪费.
- 牛肉链中的积累有助于级联效应和环境压力.
- 需要有针对性的改进来应对与有关的挑战,并促进巴西牛肉部门的可持续性.
