When the project was launched, the area comprised mostly degraded land, the result of indiscriminate logging that took place between the 1950s and 1980s, and had yet to be reforested.

A second project will restore a degraded site outside the city of Yan'an, Shaanxi Province.

In order to eliminate biofilms, the first step is to degrade the organic matrix using enzyme.

In 2021, Hilton Shenzhen Shekou Nanhai in Guangdong province introduced a set of smart kitchen waste treatment equipment to degrade all kitchen waste in the hotel into carbon dioxide, water and harmless organic fertilizer.

The hotel degraded 390 tons of kitchen waste and produced about 20 tons of organic fertilizer in a year, which is used for the hotel's landscaping and gardening.

According to a statement issued by the university, the radiation can kill viruses or pathogenic microorganisms and degrade toxic pollutants in wastewater by using gamma rays, or high-energy electron beams generated by electron accelerators.

As a very fast-growing plant that can thrive on degraded soils, bamboo is often considered an ideal choice to fight climate change.

"Promoting use of reusable packaging boxes can also reduce the amount of regular plastic wrapping materials such as single-use bags, tape and filling, which may take hundreds of years to be degraded in landfills and will cause irreversible damage to the environment if handled improperly," Zheng said.

The technology has been applied in more than 90 counties, and is helping to restore the degraded grassland and improve farmers' incomes.

"Pollution from industry and poor farming practices has degraded the land and water quality in the middle and upper reaches of the Yangtze River Basin, causing about $37 billion per year in agricultural productivity losses," said ADB Senior Natural Resources and Agriculture Specialist Suzanne Robertson.

Furthermore, we will promote the exchange of knowledge, best practices and other forms of cooperation for conservation and sustainable management of forests, regeneration and reforestation of degraded areas.12.
