$\text{Garbage in equals garbage out.}$
Every chemical reaction that HAS EVER BEEN PERFORMED obeys conservation of mass. You start with $1 \cdot g$, $10 \cdot g$, $1 \cdot k g$, $10 \cdot \text{tonnes}$ of reactant from all sources and at most you are going to get $1 \cdot g$, $10 \cdot g$, $1 \cdot k g$, $10 \cdot \text{tonnes}$ of product.
