  1. Copper recycling expertise Recently, there has been growing interest in developing efficient and selective catalytic processes for the conversion of carbon dioxide (CO2) to valuable chemicals such as ethanol. In this regard, metal-organic frameworks (MOFs) have emerged as promising solid catalysts due to their tunable pore structures, high surface area, and versatile chemistry. In a recent study, a team of researchers developed a new MOF catalyst featuring cooperative copper centres that offers high selectivity towards the conversion of CO2 to ethanol. The catalyst was prepared by incorporating copper ions into the pores of a MOF called HKUST-1, which is known for its high stability. The researchers found that the presence of multiple copper ions in close proximity to each other within the MOF framework created a synergistic effect that promoted the reduction of CO2 to ethanol with high selectivity. The copper centres cooperatively activated the CO2 and then catalysed the conversion of the resulting intermediate species to ethanol. The team used a combination of experimental techniques and computational modelling to understand the mechanism of this cooperative behaviour. They found that the copper ions interacted with each other through bridging oxygen atoms in the MOF framework, which allowed for efficient electron transfer between them and facilitated the reduction of CO2. In addition to its high selectivity, the MOF catalyst also exhibited high stability over multiple catalytic cycles. The researchers attribute this to the strong interaction between the copper ions and the MOF framework, which prevented the leaching of the metal species. Overall, this study demonstrates the potential of MOFs as promising solid catalysts for converting CO2 into high-value chemicals such as ethanol, and highlights the importance of cooperative interactions between metal centres for achieving high catalytic activity and selectivity Scrap metal utili Copper scrap smelting technologies Copper shredding technology Copper sheet scrap Copper scrap monitoring Metal scraps reclamation

  2. Copper scrap market demand Copper is a widely used metal in various industries, including construction, electronics, automotive, and telecommunications. The price of copper is affected by several factors, including supply and demand, global economic trends, geopolitical events, currency fluctuations, and production costs. Here are some of the key factors that influence the price of copper: 1. Supply and demand: The basic rule of economics states that if the demand for a commodity exceeds its supply, the price will increase. On the other hand, if the supply exceeds demand, the price will fall. The same law applies to copper prices. The demand for copper is high due to its versatile properties, such as its ability to conduct electricity and heat, corrosion resistance, and ductility. The supply, on the other hand, is limited, as copper is a finite resource and mining requires considerable investment. 2. Economic trends: Copper prices are sensitive to changes in the global economy, especially industrial growth. High levels of industrial activity, particularly in emerging markets such as China and India, lead to increased demand for copper, boosting its price. Weak economic conditions can lead to reduced demand, causing the price to dip. 3. Geopolitical events: Political instability, conflicts, and natural disasters can affect the price of copper. For instance, mining operations may be disrupted or halted due to political unrest or natural disasters, leading to reduced supply and increased prices. 4. Currency fluctuations: The price of copper is determined in US dollars. Changes in currency exchange rates can affect demand and supply, and ultimately, the price. For example, if the US dollar strengthens against other currencies, copper prices may increase, as it becomes more expensive for buyers in other currencies. 5. Production costs: Mining copper requires significant investment in exploration, extraction, and processing. The cost of production, including labor, energy, and equipment, can affect the price of copper. If the cost of mining copper increases, producers may need to sell it at higher prices to remain profitable. In conclusion, the price of copper is influenced by a multitude of factors, making forecasting its future price challenging. However, keeping a close eye on trends in supply and demand, global economic conditions, geopolitical events, currency fluctuations, and production costs can provide insights into changes in copper prices Sustainable metal recycling Copper scrap recycling industry Copper scrap baling and shredding Copper scrap shipping Scrap copper sales and marketing Sustainable practices in metal recovery
