More than 10 million tonnes of UK waste is incinerated in energy from waste plants each year, making a considerable contribution to UK energy demand. The emissions from waste incinerators are regulated by the Environment Agency through the Environmental Permitting Regulations which sets stringent emission limit values for a wide range of pollutants, including, particulate, VOCs, CO, HCl, HF, SO2, NOx, heavy metals and dioxins/furans. The emissions control system for waste incinerators represents a major proportion of the capital and operational costs. The emissions of dioxins and furans from waste incinerators into the atmosphere are of considerable public, political and scientific concern. The issue around dioxins/furans is associated with their high toxicity, significant health hazard and resistance to degradation in the environment. Dioxins/furans cause damage to the human immune, nervous and reproductive systems and are also suspected carcinogens. There is consequently concern over the negative effects on human health and the environment of long-term exposure to even very small amounts of dioxins/furans. Impending legislation under the EC Industrial Emissions Directive that will be transposed into UK Law via the Environmental Permitting Regulations has set mandatory stringent new Daily Emission Limit values for waste incinerators. Dioxin/furan emission limits are to reduced from 0.1 ng m-3 to 0.01 ng m-3 for most incinerator installations. The current most common method for control of dioxin/furan emissions uses added activated carbon reagent for the adsorption of the dioxins/furans from the flue gas followed by capture using fabric filter bags. The use of activated carbon is a high cost method and merely transfers the dioxins/furans to the flue gas control residue and subsequent disposal to high cost hazardous waste landfill. The aim of this research proposal is to develop a novel, low cost, low temperature (~150 C), non-thermal plasma-catalyst process to decompose dioxins/furans under flue duct conditions simulating those of typical waste incineration flue gases. A complementary study using model chlorinated aromatic model compounds will aid a mechanistic interpretation of the decomposition of dioxins/furans under non-thermal plasma-catalysis conditions, aiding the development of the dioxin/furan control system.

英国每年有超过 1000 万吨垃圾被垃圾处理厂焚烧成能源，为英国能源需求做出了巨大贡献。废物焚烧炉的排放由环境局通过《环境许可条例》进行监管，该条例对多种污染物设定了严格的排放限值，包括颗粒物、VOC、CO、HCl、HF、SO2、NOx、重金属和二恶英/呋喃。垃圾焚烧炉的排放控制系统占资本和运营成本的主要部分。废物焚烧厂向大气中排放的二恶英和呋喃引起了公众、政治和科学界的广泛关注。二恶英/呋喃的问题与其高毒性、严重的健康危害和在环境中不易降解有关。二恶英/呋喃会对人体免疫、神经和生殖系统造成损害，也被怀疑是致癌物质。因此，人们担心长期接触即使是极少量的二恶英/呋喃也会对人类健康和环境产生负面影响。 欧盟工业排放指令即将通过的立法将通过环境许可条例转化为英国法律，为垃圾焚烧炉设定了强制性、严格的新每日排放限值。大多数焚烧炉装置的二恶英/呋喃排放限值从 0.1 ng m-3 降至 0.01 ng m-3。目前控制二恶英/呋喃排放的最常见方法是使用添加活性炭试剂来吸附烟气中的二恶英/呋喃，然后使用织物滤袋捕获。使用活性炭是一种高成本方法，并且仅将二恶英/呋喃转移至烟气控制残留物并随后处置至高成本的危险废物填埋场。 本研究计划的目的是开发一种新型、低成本、低温（~150°C）、非热等离子体催化剂工艺，在模拟典型垃圾焚烧烟气的烟道条件下分解二恶英/呋喃。使用模型氯化芳香族模型化合物进行的补充研究将有助于对非热等离子体催化条件下二恶英/呋喃分解的机理解释，从而有助于二恶英/呋喃控制系统的开发。
