目前提出了多种废物气化技术作为传统废物发电（WtE）工厂的替代方案。由于缺乏运营经验和可用数据零碎，评估其潜力变得困难。在定义了分类和评估废物气化技术的概念框架后，本文将两种拟议技术与传统垃圾焚烧发电厂进行了比较。性能由米兰理工大学开发的专有软件进行评估，并在一组连贯的假设的基础上进行比较。由于两种气化技术均配置为“两步氧化”工艺，因此其能源性能与传统工厂非常相似。可能证明其采用的潜在好处涉及材料回收和操作/排放控制：以非氧化形式回收金属；以惰性、玻璃化形式收集骨灰；燃烧控制；减少某些污染物的产生。
A number of waste gasification technologies are currently proposed as an alternative to conventional Waste-to-Energy (WtE) plants. Assessing their potential is made difficult by the scarce operating experience and the fragmentary data available. After defining a conceptual framework to classify and assess waste gasification technologies, this paper compares two of the proposed technologies with conventional WtE plants. Performances are evaluated by proprietary software developed at Politecnico di Milano and compared on the basis of a coherent set of assumptions. Since the two gasification technologies are configured as “two-step oxidation” processes, their energy performances are very similar to those of conventional plants. The potential benefits that may justify their adoption relate to material recovery and operation/emission control: recovery of metals in non-oxidized form; collection of ashes in inert, vitrified form; combustion control; lower generation of some pollutants.
