ROBUST:Regeneration Of Brownfield Using Sustainable Technologies

ROBUST代表使用可持续技术再生布朗菲尔德。“布朗菲尔德”是以前开发过的土地，有时是为了工业目的，而“格林菲尔德”则从未开发过。布朗菲尔德的土地有时被工业污染物污染。世纪的大多数新建筑将建在布朗菲尔德土地上，因为政府正试图保护格林菲尔德土地。许多布朗菲尔德在重新开发之前需要去除工业污染物（补救）。低价值（商业术语）的布朗菲尔德通常不受房地产开发商的关注，污染程度也很低，但这些土地通常位于社区中心，为人们提供了最近的乡村。因此，它们可能对人们的健康和福祉产生重大影响。ROBUST将与当地社区合作，回收和修复这些低价值的布朗菲尔德，以改善当地环境和提高福祉。ROBUST的可持续技术包括使用工业“废物”产品。这些“废物”实际上是有价值的矿物，具有良好的土壤修复性能;这些矿物，如氧化锰，已经天然存在于土壤中，并形成了土壤天然防御系统的很大一部分，以抵御人为的工业污染。这些矿物质将被添加到布朗菲尔德土地的土壤中，并将有助于将汽油等有机污染物转化为无害的副产品，并将任何金属污染物固定在地下深处。使用“废物”产品意味着减少送往垃圾填埋场的数量，并提取更少量的初级骨料，所有这些都使我们的社会更可持续。ROBUST还将开发一种新的现场设备，以便更快、更安全地收集布朗菲尔德场地的污染物数据。我们将使用新发现的远红外太赫兹辐射来“看到”现场的污染物。这种辐射是完全安全的，波长刚好超过可见光。与其他形式的辐射（如紫外线辐射）不同，太赫兹非常擅长识别污染物，而不会受到背景土壤的干扰。新设备不仅将彻底改变现场调查工作，从而为污染土地行业节省数十万英镑（通过减少在哪里钻孔和在哪里修复的不确定性），而且还将大大提高我们对污染物如何与土壤中矿物质相互作用的理解。我们对布朗菲尔德土地修复技术如何应对洪水等各种气候变化情景特别感兴趣。可持续技术的试点研究将在大型有机玻璃立方体容器中进行，公众将能够观察布朗菲尔德土地的横截面（土壤和植被表面，如草）。雨水通过土壤产生的渗滤液将告诉我们污染物如何在土壤中移动。新的太赫兹现场设备提供的改进的数据收集将提供足够的信息，用于对土壤中的污染物如何与修复矿物相互作用进行详细的计算机建模。计算机模型将有助于减少与布朗菲尔德再生相关的公共和环境健康风险的不确定性，并了解修复土壤将如何受到洪水等事件的影响，ROBUST旨在与当地社区进行双向信息交流。当地社区通常拥有大量关于布朗菲尔德的信息，可以帮助工程师了解现场可能存在的污染物以及污染物的位置。当地社区还可以帮助工程师了解他们对场地的看法，以及他们对场地最终用途的设想。

ROBUST stands for Regeneration Of Brownfield Using Sustainable Technologies. 'Brownfield' is land which has been previously developed, sometimes for industrial purposes, as opposed to 'greenfield' which has never been developed. Brownfield land is sometimes contaminated with industrial pollutants. The majority of new buildings in the 21st Century will be built on brownfield land as the Government is trying to preserve greenfield land. Many brownfield sites require the removal of industrial pollutants (remediation) before they can be redeveloped. Low-value (in commercial terms) brownfield land is often of less interest to property developers and only marginally polluted but these sites are often situated in the heart of communities and provide people's nearest countryside. For this reason, they may have a significant impact on people's health and wellbeing. ROBUST will engage with local communities to reclaim and remediate these low-value brownfield sites with the aim of improving the local environment and enhancing wellbeing.The sustainable technologies in ROBUST involve using 'waste' products from industry. The 'wastes' are actually valuable minerals which have excellent soil remediation properties; these minerals such as manganese oxide are already naturally present in soil and form a large part of the soil's natural defence system against man-made industrial pollution. These minerals will be added to the soil on brownfield land and will help transform organic contaminants such as petrol into harmless byproducts and immobilise any metal contaminants deep within the ground. Using 'waste' products means sending less to landfill and extracting smaller quantities of primary aggregates all of which makes our Society more sustainable.ROBUST will also develop a new piece of field equipment for quicker and safer data collection on contaminants at brownfield sites. We will be using the newly discovered far-infrared terahertz radiation to 'see' contaminants on site. This radiation is completely safe and has wavelengths just beyond visible light. Unlike other forms of radiation (such as ultraviolet radiation) terahertz is very good at identifying contaminants without any interference effects from the background soil. Not only will the new device revolutionise site investigation work, thereby saving the contaminated land industry hundreds of thousands of pounds (by reducing uncertainty about where to drill boreholes and where to remediate) but it will also allow a vast improvement in our understanding of how contaminants interact with minerals in soil. We are particularly interested in how brownfield land remediation technologies will react to various climate change scenarios such as flooding.Pilot studies of the sustainable technologies will be carried out in large Perspex cubic containers where the public will be able to observe a cross-section of the brownfield land (both the soil and the vegetated surface e.g. grass). Leachate generated by rain passing through the soil will tell us about how contaminants move within the soil. The improved data collection provided by the new terahertz field equipment will provide sufficient information to carry out detailed computer modelling of how the contaminants in the soil interact with the remediative mineral. The computer model will help to reduce uncertainty about both public and environmental health risks associated with brownfield regeneration as well as understand how the remediated soil will be affected by events such as flooding which are now happening more often due to climate change.ROBUST aims to work with local communities in a two-way exchange of information. Local communities often hold large quantities of information on brownfield land and can help engineers to understand what and where pollutants might be on site. Local communities can also help engineers understand their perceptions of the site and their ambitions for what end-use they envisage for the site.
