SALTROMEX changes the economics of smaller scale ...
Steel slag is calciumsilicatic, with a CaO range of 38–48%, and it has a SiO 2 range of 11–20%. The Fe in steel slag is in the form of steel, FeO, and iron-bearing minerals. These components can be separated from the steel slag by magnetic separation for the sinter and blast furnace or may be used in steelmaking.
The mass production of steel is inevitably accompanied by large quantities of slags. The treatment of ironmaking and steelmaking slags is a great challenge in the sustainable development of the steel industry. Japan and China are two major steel producing countries that have placed a large emphasis on developing new technologies …
The New Zealand government has kicked off its mission to phase out single-use and hard to recycle plastics by 2025, after its ban on single-use plastic shopping bags in 2019. This includes bans on ...
Choi et al. [ 3] described two possible methods to recycle ladle slag: (a) by pouring molten ladle slag to another ladle, at time (taking advantage of the heat) and (b) by making a ladle slag ingot. The latter option mentioned is complex because of the unstable method used for making ingots.
In 2019, 123,714 tonnes of paper and cardboard were recycled in New Zealand. Around 40% of New Zealand's landfilled waste is composed of organic materials, which could be composted or reused. Only 29% of plastic bottles in New Zealand are recycled, well below the global average of 50%. New Zealand has more than 800 soft …

3.3. Physical properties. The typical copper slag is generally black or dark brown in colour and its density is in the range of 3.2 – 4.5 g/cm 3, mainly depending on the content of Fe (Sarfo et al., 2017b).The average true density of copper slag is approximately 3.8 g/cm 3, which is denser than the ordinary natural aggregates (Shi et al., 2008). ...
RECYCLING FACTS. The recycling of metals has the potential to cut the production of greenhouse gas emissions by 300-500 million tons. Using scrap metal in lieu of ore generates 97% less mining waste and uses 40% …
Here's how it works: The cotton textiles are sent back to Little Yellow by the consumer. Any brands can be sent to them, but they must be cotton. Once the textiles arrive at the recycling plant, the cotton is dissolved and turned into new, raw materials that look like paper sheets. The 'paper sheets' can then be made into ...
07.29.2014. Slag is a by-product of the metallurgical smelting process. Slag has a double role: it permits removal of impurities, known as gangue, from the melt by forming oxides. It also allows exchange reactions with the liquid metal, permitting control of the process in order for the desirable elements to stay in the melt while the others ...
This consultation sets out three proposals to transform recycling in Aotearoa New Zealand: 1 Container Return Scheme. 2 Improvements to kerbside recycling. 3 Separation of business food waste. These three proposals are part of a longer-term shift toward a circular economy, where packaging is made of materials that …

During the blast furnace process limestone (CaCO 3) flux is added, to collect the waste products produced: silica (SiO 2), phosphorus pentoxide (P 2 O 5), calcium sulfide (CaS), magnesia (MgO) and alumina (Al 2 O 3).This forms blast furnace (BF) slag, which floats on top of the surface of the hot metal (Peters, 1982).The blast furnace is …
Obstacle 1: Getting the Glass to the Recyclers: The problem of geography. New Zealand has one glass recycling plant, in Auckland, run by Owens-Illinois (called O-I for short). This is the only place in New …

The transformation of steelmaking slag into a strong structural material through high gravity carbonation (Chang et al., 2012). Now known as the carbstone method (Quaghebeur et al., 2015), it consists of three steps: pre-treatment, shaping and curing. The BOS slag is first homogenized into a powder and then mixed with the appropriate …
Slag recycling and reuse – GREENY approach. The global demand for raw materials is growing exponentially with the world's urbanization and technological progress. The growing raw materials consumption is an economical threat due to the increasing scarcity of critical materials, but also an environmental threat with increased amounts of ...
Glass Collection Bins. 120 or 240 litre wheelie bins are an efficient method for collecting glass bottle, jars and cans. The 240L bins hold approximately 300 x 330ml or 100 wine bottles. Colour separation is not required for glass collection bins. Bin collection is either on-demand or a regular call schedule depending upon volumes.
What the research found. While Brazil and New Zealand were the worst for recycling, the best country was Hong Kong, closely followed by Portugal. The 3 most recyclable products were the Coca-Cola Mini 6 pack, Dove Body Wash and San Pellegrino Sparkling Water. The least recyclable were Pringles, KitKat, and M&M Peanut chocolates.
