2B4UR

2B4UR stands for “2-way Bioremediation for Urban Redevelopment”, and refers to a unique environmental engineering technology that relies on microbial activity to clean up urban soils contaminated by petroleum hydrocarbons and other hazardous pollutants and chemicals. 2B4UR has been utilized in North America since the early 1990s, and is now seen as one of the most cost-effective and viable methods to reduce levels of contamination in urban soils and groundwater.

2B4UR works in two distinct ways: using biological methods and applying chemical/pharmaceutical engineering techniques. Biological methods involve exposing the contaminated soils to a cocktail of soil microbes known for their ability to degrade and break down a wide range of petroleum hydrocarbons and chemicals with oxygen or other electron donors. This process is often termed "bioremediation". Alternatively, chemical/pharmaceutical engineering methods include applying chemical compounds and specific oxidation agents to convert soil contaminants into less hazardous forms or to help the microbes break them down.

The application of 2B4UR has tangible benefits. One is that it eliminates the need for hazardous soil excavation, which is commonly required in other remediation strategies. The process produces no adverse environmental impacts and can dramatically reduce or fully eliminate the problem of soil and groundwater contamination. It also substantially lowers long-term maintenance costs and can help boost public confidence in a redevelopment project.

The main working principle of 2B4UR is to reduce the concentration of harmful chemicals and substances in urban soils and groundwater by applying biological and chemical/pharmaceutical engineering techniques.The process not only helps remove hazardous pollutants from the environment, but can also be applied cost-effectively and with minimal disruption to redevelopment projects. It can be used in a variety of ways, including treating contaminated soils prior to development or redeveloping and remediating contaminated sites.

In general, 2B4UR can be a highly useful and cost-effective tool in the clean-up of contaminated soils in urban areas. The technology has already been successfully applied in a number of cities to restore environmental safety. By providing one of the most effective means of remediating urban soils contaminated by petroleum products and other hazardous pollutants, 2B4UR can help reduce long-term health risks, protect public health, and protect the environment from further damage.
