In this endeavour, we are able to draw on our extensive range of refractory products.
Iron and steel constitute over 90% of all metal production and a similar fraction of the scrap metals market. Steel mills consume about three quarters of the scrap, and iron and steel foundries consume the remainder to produce ferrous castings.
Economic Facts of Iron & Steel Recycling
•Almost 40% of the world’s steel production is made from scrap.
•Every ton of recycled steel can help saving 1.4 ton of iron ore.
•Conversely, a steel can land-filled will take 100 years to vanish.
•Steel is the most recycled material on earth! In Luxembourg, 2,292 tons of steel packaging have been collected in 2013.
•Recycling one tonne of steel saves 1,100 kg of iron ore, 630 kg of coal, and 55 kg of limestone.
•CO2 emissions are reduced by 58% through the use of ferrous scrap.
•Recycling one tonne of steel saves 642 kWh of energy, 1.8 barrels (287 litres) of oil, 10.9 million Btu's of energy and 2.3 cubic metres of landfill space.
•Recycling steel uses 75% less energy compared to creating steel from raw materials - enough to power 18 million homes.
•Steel recycling uses 74% less energy, 90% less virgin materials and 40% less water; it also produces 76% fewer water pollutants, 86% fewer air pollutants and 97% less mining waste.
•Steel automobile frames contain at least 25% recycled steel and a typical electrical appliance will usually be made of 75% recycled steel. Steel cans consist of at least 25% recycled steel.
Dear Readers,
In this presentation, I have tried to explain main raw material sources of iron making process. Also, with my experience, I have tried to give a concept about the plant engineering related to raw material. I hope that, this presentation will be helpful for young engineers. With this presentation they will get a broad idea about the raw material, based on which they can study more on the subject.

Abfad ltd Company Profile November 2014Chris Haritou
Innovative Project Management and Solution
Development of Rope Access Projects
Abfad Ltd takes a unique approach to Rope Access Services; we focus on developing rope access skills for trade personnel. Time‐ served
welder, for example, can be taught the specific rope access skills however methodologies for actually performing hot work at height need
to be fine‐tuned to carry out welding work efficiently, productively and safely, the same level of expertise can be delivered to all trades by
short in house training.
Many rope access personnel now train on a three day blasting and spraying course through OPITO (Offshore Petroleum Industry Training
Organisation) and promote themselves as blaster/sprayers, they do not have the necessary skills to perform this work safely or provide the
quality necessary for clients. Abfad can deliver scalable trade testing to ensure that personnel mobilising do have the necessary trade skills to
perform the work.
We believe the correct process is to train trades persons to work at height so they can provide a quality service for clients.
Unskilled persons with a rope access level 1 or 2 need to be apprenticed with skilled labour so they can attain the necessary skills to be a
valuable asset to a company. ABFAD Ltd take this approach with our personnel and train necessary skills as required for projects.
Falls from height are the most frequent cause of fatalities at construction sites and continue to be a major concern with the HSE. It is
particularly important that Health and Safety Systems are second to none when working at heights. ABFAD has a remarkable history of safety
during our 16 years in business. Although I have good experience in H&S offshore and onshore over the past 30 years I maintain training in Occupational Health and Safety and am currently finishing an NVQ level 5 in Occupational Health and Safety, modules I am informed are equivalent to Degree Level.
World‐class Technology Solutions
Abfad have also developed a patented double skin lining system for underground and above‐ground storage tanks.that is currently in the final stages of accreditation from Europe’s most significant assessment arm TUV Nord. The system has already generated huge interest on the worldwide stage, with significant enquiries being generated from as far afield as China, Saudi Arabia, United States and Canada.
FUELVAC® double skin liner is the most environmentally‐friendly system developed and in use in the UK and, we believe, the World.
The system uses engineered manufactured materials and solvent‐free resins which creates a seamless liner.
A description of the features and benefits of the system is also available on the website.
Since 2006 to present time over 100 underground storage tanks have been installed within the UK and in 2011 Abfad double skin lined two tanks for Simon Storage. FUELVAC® double‐skin liner installed with vacuum leak detection monitoring is the highest fo
Anese began its activities in the agricultural field, later branching into works connected with irrigation and flood management, together with earth movements and the removal of lithoid materials.
Experience and skills earned through time and the level of precision realised have allowed the company to widen its horizons in the field of road construction and urban planning, aqueducts and sewage management as well as other specialised fields, both private and public including prompt emergency assistance to the "Protezione Civile" in the event of natural disasters. In an afford to diversify their technical/commercial competence, the field of work has recently been extended to include projects in horizontal directional drilling.
Another sector of special application is land stabilisation using new technologies for the recycling of terrain, and land reclamation. This application can be employed for road and railway civil engineering (embankments etc..) as well as for the construction of airports and other infrastructural works.
Anese also offers important technical contributions to the field of agriculture in the creation of underground drainage systems to avoid the accumulation of surface water owing to rainfall, maintaining a constant underground water level during periods of heavy rainfall. The result of this is increased land productivity.
"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

Prevalence of Toxoplasma gondii infection in domestic animals in District Ban...Open Access Research Paper
Toxoplasma gondii is an intracellular zoonotic protozoan parasite, infect both humans and animals population worldwide. It can also cause abortion and inborn disease in humans and livestock population. In the present study total of 313 domestic animals were screened for Toxoplasma gondii infection. Of which 45 cows, 55 buffalos, 68 goats, 60 sheep and 85 shaver chicken were tested. Among these 40 (88.88%) cows were negative and 05 (11.12%) were positive. Similarly 55 (92.72%) buffalos were negative and 04 (07.28%) were positive. In goats 68 (98.52%) were negative and 01 (01.48%) was recorded positive. In sheep and shaver chicken the infection were not recorded.
UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
