Vecor Ltd: New Tile Factory in Zibo a Catalyst for Change

- Zibo, China

Vecor Limited is a company dedicated to green technology, operating in Hong Kong with business operations in Australia, India, Italy, and the Philippines. The most recent processing and manufacturing line was established in Zibo City, in the Shandong province of China. The goal of the factory in central China is keep the world's largest industrial solid waste out of the air, waterways and landfill. The project aims to use the supply of fly ash as an industrial grade mineral for high value industries such as plastics, paints and ceramics where fly ash would be replacing much more expensive raw materials than cement. Due to the well known logistical issues of exporting ash in high density, inland locations such as Zibo, many coal fired power stations continue to landfill their ash in record numbers.

Mr. Alex Koszo, Founder of Vecor and owner of the commercial solutions and patents invented by Vecor: “The Zibo factory is proving that the value of products made from recycled fly ash can be so high that they can profitably exported to any location in the world.”

This is big news for thermal power stations in rural areas in places like South Africa and India, who’s ash landfilling is becoming an issue both economically and environmentally. 

The original inventions used by Vecor were conceived and patented by the University of New South Wales, Australia in 2002 & 2003.

Vecor's Systema Leonardo?, the technology being implemented in Zibo, China, enables thermal power stations to safely and comprehensively eliminate fly ash liabilities by allowing their fly ash to be converted into high value building products such as grey porcelain ceramic tiles for floor and wall coverings. Systema Leonardo? also creates significant environmental and cost savings over traditional ceramic manufacturing processes, through water, energy and labor savings whilst complying with the highest international quality standards.

Vecor’s Systema Leonardo has successfully developed and commercially launched its industrial technology to extract industrial grade high quality minerals from coal ash that is usable by industries that produce 5-10 times valuable products than cement.

The positive indication of such technology for the power generation industry and higher value products manufacturers is significantly positive.

In the attached presentation, presented in the dual languages of English and Chinese, you can learn about the following

1. Systema Leonardo technology introduction

2. Value creation business model

3. Long-term highly profitable green business opportunities

4. China market size and coal ash by numbers

5. Details of offer to power stations to eliminate the financial and environment burden of

landfilling

6. Invitation to participate as investor

Vecor was present that CAA2018, in Shuozhou,  Shanxi Province, China, this past September. In attendance were a strong delegation, including participation in international commercial MOI signing ceremony, for the Leonardo system.

Research Highlight: Acid Extraction of Valuable Resources in Fly Ash and Various Utilizations of Acid Slag

- Beijing, China

Aluminium and rare earth mineral extraction was a well-explored topic at AsianCAA’s latest Coal Ash Asia event, in Beijing, last July.   Vice Professor Li Fang Fei, from JiLin University, shared her research pertaining to acid leaching in order to extract precious rare earth minerals. Jilin University is a key collaborator with the China Building Materials Academy (CBMA), and the Institute for Technical Information for the Building Materials Industry, our co-hosts of Coal Ash Asia. The university's chemistry department contributes essential research to the topic of waste utilization and management.  Below is Professor Li Fang Fei’s abstract, discussing her latest research.

Abstract: Fly ash is the main solid waste of power plants. After combustion, the aluminum, rare earth and other valuable resources in the raw coal are further enriched in the fly ash. That makes the high Al2O3 content in the fly ash of Inner Mongolia region (up to 50 wt % ). Aluminum, iron, gallium, and other rare earth resources in fly ash could be extracted by acid leaching process. And followed by resin separation, enrichment leaching, and crystallized purification process, various valuable resources could be successfully separated and purified to an ideal level. Such leaching method is not only applicable to the high-active CFB fly ash, but also suitable for the OF fly ash whose amount is much larger than the former. In addition, the amount of acid leaching slag of fly ash is very small, which is composed of porous SiO2 with ideal purity and highly reactivity. Such "white mud" could be produced as building materials, artificial zeolites, inorganic fibers, catalyst carriers, and other useful products, which promotes the governance and comprehensive utilization of fly ash.

Jilin University will be returning contributors to Coal Ash Asia 2018. For more information, or to register, please follow the links below. If you would like to be sent an information package regarding our event, please input your email below.

Research Highlight: Synthesis of High Quality Zeolites from Coal Fly Ash

- Perth, Australia

Dr. Kevin Li (Gang Li), participated in CAA2017 on behalf of the Centre for Energy, School of Mechanical & Chemical Engineering at the University of Western Australia in Perth, Australia. Dr. Li, a returning speaker to Coal Ash Asia, focused his presentation on synthesizing zeolites and necessary related conditions. The below abstract is an overview of the research presented at the conference. For more of Dr. Li’s publications and research, please click the link at the bottom of the abstract.

Abstract: Coal fly ash is a hazardous industrial waste generated from coal combustion and has been considered as an appropriate raw material for zeolite synthesis. In this study, synthesis of a high-quality type A zeolites (471m /g surface area) from fly ash at high conversion rate (98.2% aluminium and 96.5% silicon) has been achieved via a two-step alkali fusion and hydrothermal procedure. Furthermore, in preparation for production in commercials scale, up scaling of the developed synthesis process has been undertaken by using 150L reactor. More importantly, we tracked the migration of elements and quantified their distribution from fly ash to product zeolites and waste water throughout the synthesis process. Metalloid elements including arsenic and selenium, and those with strong amphoteric properties such as molybdenum were found highly mobile and mostly collected in the waste water. In comparison, less than 20% of heavy metal elements of weak amphoteric nature including copper, chromium and lead originated from the fly ash went to the waste water; the rest of these three heavy metals along with almost all of the cadmium, iron and nickel were fixed into the product zeolites. Despite the accumulation of hazardous elements in product zeolites, none of them was leachable under various harsh conditions, ensuring safe applications of such zeolites.

Autoclaved Aerated Concrete: CCPs Growth in Asia Pacific

Between 2015 and 2021, the global autoclaved aerated concrete market is expected to increase by just under $2 billion USD.  AAC is increasing in industry wide use due to its light weight and versatility. The construction material consists of fly ash and gypsum, both biproducts of burning coal to make energy, and much less costly than their alternatives, sand and anhydrite.  The material also consists of lime, cement, and aluminum powder. Construction companies are increasing their use of this material as it is not only more cost efficient, but also provides wider durability to seismic fluctuation, intense heat, and pests. The material itself also saves the manufacturer or construction company in water and energy usage.  Autoclaved aerated concrete is widely used in Europe and North America.

AAC materials can either be used instead of or to repair common building materials. Application can be seen in most real estate areas including residential, industrial and commercial. However, the majority of the AAC market has been residential since its inception, and continuing throughout 2017 with a third of the overall market. The product types of autoclaved aerated concrete are distributed into tiles, panels, blocks, lintels and others.

The growing market is propelled by elements such as the increased importance of utilizing green building materials, the use of recycled materials themselves (fly ash, etc), and its superiority to commonly used materials for the same purpose.

Currently, limited adoption is due to high start up costs associated with AAC, and because manufacturing facilities are not yet commonplace, resourcing and logistics becomes problematic.

As adaptation grows however, and infrastructure is set in place, the forecast for AAC paneling is projected to grow almost 8% in the next 5 years.

Globally, Europe has lead in market consumption. However, the Asia Pacific region, including countries like China, Thailand, Malaysia, Singapore and Indonesia are expected to increase consumption by over 10%, also within the next 5 years.

Opportunities in the AAC market are real as there is strong interest in China, India and other densely populated regions who would benefit from disaster resistant structures made from coal combustion products (CCPs).
