400 mill ons phosphate reserves

A) The total reserves of a non-renewable resource are 400 million tons. Annual consumption, currently 25 million tons per year, is expected to rise by 1% each year. After how many years will the reserves be exhausted?B) Instead of increasing 1% each year, suppose consumption was decreasing by a constant percentage per year.

Known reserves might last 300–400 years at current world production rates of 160–170 million MT of fertilizer/year. Because phosphorus fertilizer production is expected to increase by 2–3%/year and use by as much as 5% during the next 5 years, the life expectancy of reserves could be much shorter ( Heffer and Prud'homme 2010 ).

Phosphorus Research Initiative, mined phosphate rock supplies are expected to peak around 2033, while other authors (United States Geological Survey [USGS], 2012) feel current reserves will last 300-400 years leaving little cause for concern.

The nanofibers are intricately woven together with a uniform diameter about 400 nm, and seem like a spider web (Fig. 6b). Na 3 V 2 (PO 4) 3 nanoparticles are mounted on the nanofibers and there are also a lot of gaps between the fibers, which can increase the contact area between the active material Na 3 V 2 (PO 4) 3 and the electrolyte (Fig. 6c).

But its phosphate industry, mining around 45,000 metric tons a year, is producing nothing like in the past.
