It is projected that by 2050 about 64% of the developing and 86% of the developed world will be urbanized. Urbanization, if not managed properly, can create an array of environmental issues, such as flooding and surface water pollution due to increases in the proportion of impermeable surfaces. Green infrastructures, such as green roofs and rain gardens, have been increasingly installed in cities for environmental benefits, such as storm water management, which reduces flooding and prevents pollutants from being washed into surface waters. However, there is a shortage of specifically engineered substrates for the retention of water and nutrients, especially the water pollutant phosphorous (P). Mar-Co Clay Products Inc. (Mar-Co) is specialized in producing, distributing, and designing clay-based products (e.g., crushed bricks) for customized sports fields, especially baseball fields. Our previous research showed that some crushed brick products have the capability of removing and retaining P, and retaining or draining water, depending on the particle sizes and other chemical and physical properties of these products. This project will characterize the chemical and physical properties of different existing Mar-Co products, and develop new products based on Mar-Cos existing production technology and capacity. The objective is to enable Mar-Co to become a leading material supply company for the substrate needs of the green infrastructure industry, especially for water and nutrient management, namely environmental remediation.

据预测，到2050年，约64%的发展中国家和86%的发达国家将实现城市化。城市化如果管理不当，可能会造成一系列环境问题，例如由于不透水表面比例增加而造成的洪水和地表水污染。绿色基础设施，如绿色屋顶和雨水花园，已经开始
