Phytoremediation is the use of plants and associated soil microbes to reduce the concentrations or toxic effects of contaminants in the environments. In contrast, phytoremediation is a better solution to the problem. Different physical and chemical methods used for this purpose suffer from serious limitations like high cost, intensive labor, alteration of soil properties and disturbance of soil native microflora. Thus remediation of heavy metal pollution deserves due attention. Some heavy metals are carcinogenic, mutagenic, teratogenic and endocrine disruptors while others cause neurological and behavioral changes especially in children. This contamination poses a risk to environmental and human health.
Since heavy metals are nonbiodegradable, they accumulate in the environment and subsequently contaminate the food chain. The mobilization of heavy metals by man through extraction from ores and processing for different applications has led to the release of these elements into the environment. Phytotechnology as a means for remediating small sites polluted with organic chemicals is a step in promoting this technology and proving its worth for other, larger, and more complicated brownfields.
Cleanup goals seem to be achievable and could resolve in largely applied Best Management Practices (BMP), transferable to multiple sites and areas worldwide. Changing public perception is inevitably to provide a site that benefits the community. This discourse is needed to limit solutions that may work on a technological level while otherwise exclude cultural factors. The project also showcases that interdisciplinary collaborations between soil scientist and designers should be fostered to integrate the phytoremediation technology with aesthetic and cultural values to widespread the treatment of planned and abandoned gas stations or other small-sized brownfields.

Upon full remediation, a gas station can offer recreation as public green space and ecological functions that benefits society. They create modules that can be easily combined and expanded through exploration of legible design elements with spatial and aesthetical qualities.

The project demonstrates how phytotypologies, as a series of selected phytotechnology planting types, can be used in combinations for varying spatial situations due to their ability to remediate the types of contaminants present at gas stations.
These are petroleum hydrocarbon compounds that are considered lighter fractions, meaning they have characteristics that allow them to be more easily broken down. Pollutants seen at typical gas stations are organic chemicals that are derived from petroleum sources and come in many forms. The project uses an abandoned gas station as an exemplary and typical study object. This design research project showcases design models and strategies for abandoned, existing, and planned gas stations through phytotechnologies as a tool for aesthetic experience, ecological performance, and social resilience in the context of brownfield remediation and adaptive reuse.
