如已知的，可以通过作为参考不同参数进行优化的生产活动，例如生产单位成本，年收入或利润，这意味着优化应允许获得最大的经济效益的给定生产。尽管如此，优化过程或其一部分始终可能，例如通过最小化二氧化碳排放或耗水量或更普遍，资源。如果应用于同一任务，则两种不同的方法确定不同甚至令人惊讶的结果。简单和即时的应用是例如用于果汁浓度的两种操作的比较。工业上可采用的工程解决方案是多种效果蒸发（通常是三效）和热压缩的溶液。技术和经济优化涉及蒸汽成本（热源）和热电KWH的比较。最便宜的解决方案由使用kWh压缩的蒸汽（以kg表示）的量决定。如果该量高，平均超过20kg，则热压缩在经济上有利，否则不是。关于环境，热压缩是有利的，与三效相比，当用KWH压缩的Kg蒸汽等于或大于10时。因此，很明显，解决优化问题的解决方案是在经济或环境之间选择。同样有关环境，可以分析和优化许多其他操作，这将导致许多生产性选择的趋势逆转：不便宜的流程可以是环境有益的。例如，考虑冻干，例如：考虑到如此获得的产品可能不需要巴斯尿精或灭菌，碳足迹的节省是什么节省。在国内消费期间，他们也需要冷链。较轻的包装和运输将受到环境和资源消耗。Maybe it’s time to rethink the classical concepts of optimization, not only referred to the technical-economic field, and widen the horizon, considering lower ecological impact, not only in terms of reducing emissions of carbon dioxide and greenhouse gases in general, but also lower consumption of resources, water and primarily soil. This is an unavoidable commitment that, especially we Europeans must take toward the planet and future generations: the second half of the last century was for Europe the period of post-war reconstruction, freedom and economic rebirth, achieved even at the expense of protection of resources. Therefore, this century will be the period of reconciliation with environment, in all its forms. Optimizing environment must be a pre-requisite of each process, both production and decision-making. The time of second thoughts is over and the economic crisis that continues dogging us is the most clear and concrete evidence.
