2. picnicking on plants and insects. over the past 50 years, meat production has more than quadrupled leading to a global production of 320 million tonnes each year 3. today, food emissions contributes to over a quarter of global greenhouse gas emissions 4 and livestock is responsible for up to 40 of these emissions. yet, thats not all.
Because ggbs has low embodied co 2, it allows designing concrete mixes for sustainable construction. the manufacture of ggbs requires less than 20 of the energy and produces less than 10 of the co 2 emissions compared to portland cement production. ggbs is a sustainable alternative for portland cement in the production of: readymix concrete.
About Us | Nederman
By doing that, we contribute to efficient production, environmental benefits and a safer workplace. clean air is a cornerstone of sustainable production. dust and fumes generated during the manufacturing process must be efficiently captured to ensure product quality, equipment longevity, regulatory compliance and safe, healthy work environments.
Cement is a fine powder, obtained from the calcination at 1,450 c of a mix of limestone, clay, and iron ore. the product of the calcination process is clinkerthe main ingredient of cementthat is finely ground with gypsum and other chemical additives to produce cement.
The cement sustainability initiative (oecdiea and world business council for sustainable development, 2009) recommends how the industry can make changes on a global scale by promoting the best available efficiency technologies for new and existing production plants, increasing awareness of alternative fuels and encouraging clinker substitution.

G. habert, in ecoefficient construction and building materials, 2014 10.1 introduction. cement production has undergone tremendous developments since its beginnings some 2,000 years ago. while the use of cement in concrete has a very long history (malinowsky, 1991), the industrial production of cements started in the middle of the 19 th century, first with shaft kilns, which were later.
Lme Week: Sustainability And Mining – The Green
In midoctober, i participated in a hugely insightful lme week seminar panel sustainability and mining – the green revolution paradox in london. the session revolved around the central role of metals and minerals in the global transition to a lowcarbon economy and how the mining industry can become more sustainable to allow this shift to occur with minimum environmental impact.
In the iea sustainable development scenario, in which global co 2 emissions from the energy sector fall to zero on a net basis by 2070, ccus accounts for nearly 15 of the cumulative reduction in emissions compared with the stated policies scenario. the contribution of ccus grows over time as the technology improves, costs fall and cheaper abatement options in some sectors are exhausted.
In other words, cement produced as the final product of a technologically advanced process, such that emissions during unit operations (like clinker production) are minimized, is referred to as green cement. green cement is an ecofriendly product which resolves serious environmental issues and minimizes the carbon footprint of cement production.
Posted on j. concrete is a mixture of cement, gravel, sand, water and a range of aggregates. with about 10 billion tons of concrete produced every year, it is the most consumed substance in the world, second only to water.. it is also the worlds most widely used material for construction – from bridges to large buildings, concrete forms the very foundation of our infrastructure.
