WADI HANIFA

Riyadh Province, central Saudi Arabia

Due to the increasing population rate, hazardous pollution across the area of the Riyadh Province began to rise as well. Wadi Hanifa was a recreational site where many residents swam in from the beginning of time. For several years, it became known as a dumping ground surrounding urban cities. Remarkably, with the help of a decade-long project led by the Arriyadh Development Authority, this restoration project soon brought back the "life-giving valley for the people of Riyadh." The complication begins when the polluted water makes its way beneath the subfurace level of the groundwater and into the water wells. It was common for the people of the community to smell the odor and ingest the contaminated water which resulted in various waterborne diseases. 

 

Bioremediation became the answer to make this plan possible as bioremediation engineer Badr Al-Tamimi states how “there are primary producers like algae and higher plants as well as consumer organisms like birds and fishes, to make it a complete food network" - bringing back the life and beauty of this phenomenal landmark.

AMAZON RAINFOREST

Amazon Basin of South America

One of the biggest concerns circulating around the Amazon Rainforest deals with the excessive amounts of crude oil spills. In 2016, about 477,000 liters of crude oil began to leak throughout the area. This was mainly caused by the poor management and lack of maintenance of the company in charge of the pipeline. The oil spill resulted in even more danger towards the wildlife, including several species of animals ingesting soils that are contaminated with the oil. 

 

Project Micro-Bac took on this challenge to bring the environment back on the right pathway of creating a cleaner habitat with the removal of oil contamination.  

​

By using non-pathogenic microorganisms and eco-friendly nutrients, Micro-Bac was capable of taking on this challenge with the help of bioremediation pipes for subsurface inoculation. In just a few weeks, huge recovery changes could be seen - leaving the result of a complete restoration towards environmental standards. 

PASIG RIVER

Manila, Philippines

After World War II, the pollutants flooding into the Pasig River grew at an alarming high rate. This drew attention from the incoming settlers who found it easier to dispose their waste by just dumping it into the large area/canal. Despite that, population rates began to multiply around the community. This ultimately prevented the people to handle and minimize the waste disposal at a steady rate. 

 

However in 2010, rehabilitation efforts made by BioMatrix and the Danish International Development Agency incorporated bioremediation to solve the dangerous complications of pollution which also affected the health of many Filipino citizens. Manila, being the capital of the Philippines, invited many more people to live and find better jobs here. This ultimately provoked environmental issues such as the lack in access of clean water.

​

The overall objective was to find a way to use bioremediation as the solution in reducing the contaminated river with harmful and toxic bacteria, fungi, and oil. By adopting a water treatment system that comes with an oxygen transfer, this effective platform allowed for bacteria to target the pollutants in the water thus removing major toxins floating around the Pasig River.

EXXON VALDEZ

Prince William Sound, Alaska

In March of 1989, the oil tanker Exxon Valdez spilled 11 million gallons of oil in Prince William Sound, Alaska and out into the Gulf of Alaska. From this, marine life and 1,300 miles of the wild shoreline in the country were deeply affected then and even up to this date. 

 

As of 2010, reports indicate that the oil spilling caused the rate of extinction for orcas to rise. With 15 from the 22 monitored orcas dead, it leaves only one, older female left within the pod of orcas. The government even issued a statement a few years after this event stating that "there appears to be no hope for recovery."

Aside from the outcomes regarding marine life, the Pacific herring - the source for commercial fishery - declined and had to close its fishery area and has not reopened since. 

​

Many researchers fear that society today will not realize and make remarkable changes to reduce the use of oil in order to prevent another tragic spilling like Exxon Valdez. 

BIOREMEDIATION
