Waste Production to Climate Climate Change

Products made from urban, agricultural and forest waste have the added benefit of reducing the carbon footprint of modern agriculture, according to an international review by UNSW.

Professor Stephen Joseph, who visits the UNSW School of Materials Science and Engineering, said the study GCB Energy Bioger provides strong evidence that it contributes to climate change mitigation.

“Biochar can absorb carbon from the atmosphere and store it for hundreds to thousands of years,” he said.

“This study shows that biocides can build up and reduce organic carbon in the soil by up to 20 percent (average 3.8 percent). Nitrous oxide About 12 to 50 percent of emissions, including the benefits of climate change, include the use of biocides.

The findings in a recent special report on climate change and land are estimated to have significant potential for climate change mitigation.

Professor Joseph states: “At the international level, biomarkers are able to reduce carbon dioxide emissions by 300 million to 660 million tons a year.

“Compared to last year’s emissions in Australia – an estimated 499 million tons of carbon dioxide – you can see that Biocar can take many emissions. We only need permission to develop and use it. ”

Stable charcoal

Biochar is a by-product of heating biomass residues such as wood chips, animal manure, sludge, compost and green waste — a process known as pyrolysis.

The result is stable coal that can reduce greenhouse gas emissions while increasing soil fertility.

The GCB Bio-Energy Survey examines an estimated 300 papers, including 33 meta-analyzes, of many of the 14,000 biocarbon studies published in the last 20 years.

“The average crop yield has increased by 10 to 42 percent, the concentration of heavy metals in plant tissues has decreased by 17 to 39 percent, and phosphorus for plants has also increased,” says Professor Joseph.

Biochaar helps plants to cope with environmental stressors, such as diseases, and helps plants tolerate toxic metals, water stress, and organic compounds such as terraces.

Benefits for plants

For the first time, the study showed how biocides improve the root zone of a plant.

In the first three weeks, when the biocaster reacts to the soil, it can stimulate seed germination and seedling growth.

Over the next six months, improved nutrition for plants will be created in response to biocarriers.

After three to six months, biocides begin to ‘age’ in the soil and produce micrograms that prevent the decomposition of organic matter.

According to Professor Joseph, the study’s biggest reaction to biocarr was found in acidic and sandy soils, which were applied in combination with fertilizers.

“The positive effects of biocides are dependent on size and also on the dependence of biochemical properties on soil boundaries and plant nutrients,” says Professor Joseph.

“Especially in low-nutrient, tropical acid soils and wetlands such as NSW and the northern coast of Queensland can benefit greatly from biocides.

“Sandy soils in Western Australia, Victoria and South Australia, especially in arid areas affected by climate change, are also very useful.

Professor Joseph AM specializes in the production of stable biocarriers for agriculture, urban and forest residues.

Since its introduction by Indigenous Australians in the seventies, it has been exploring the benefits of biomarkers in promoting healthy soils and tackling climate change.

Biocar has been used for centuries in Australia, Latin America (especially in the Amazon Basin) and in Africa to produce healthy crops and maintain a healthy soil.

Biochar is also registered in the 17th^Th Centuries as animal food.

But since Australian researchers have been studying biocard since 2005, it has been relatively slow to start as a commercial product, with Australia producing around 5,000 tons a year.

“This is partly funded by small-scale demonstration programs, as well as by farmers and government consultants on biomarkers, regulatory barriers, and corporate capital shortages and young entrepreneurs to fund and build bakery businesses,” said Professor Joseph.

By comparison, the United States produces about 50,000 tons a year, and China produces more than 500,000 tons a year.

It needs to be economically viable

Professor Joseph, who has received the Australian mandate for Renewable Energy and Biocargars, says that in order for Biochaar to be widely accepted, it must be easily integrated with agriculture and economically viable.

“We have done science, what we do not have is enough to educate and train people, so that farmers can see the benefits of biocarts, they have enough resources to set up demonstrations to develop this new industry,” he said.

However, as large corporations purchase carbon dioxide reduction certificates (CRCCs) to offset their emissions, this is gradually changing, raising the profile of biocards in Australia.

Biocher has capabilities in a variety of applications.

A recent study by Professor Joseph b International Material Reviews It lists some of the lesser known uses of biocides, such as building materials, to reduce toxins in the soil, to grow microorganisms, to feed animals, and to improve soil fertility.

UNSW said it has partnered with a Norwegian company and university to develop a biomarker-based antimicrobial coating to kill waterborne pathogens and use them in air purification systems.
