Hydrogen has no waste is is an element of the simplest form.
hydrogen
In a normal hydrogen oxygen fuel cell, the waste products are water, and heat
They add hydrogen (from water) to make sugars.
There is no waste produced by plant and trees.
Hydrogen when burned is combined with oxygen following the reaction, 2H+O ----> H2O One of the most attractive aspects of hydrogen as a fuel is the fact that when it is combusted it produces harmless water.
Sometimes, factories dump their waste products into rivers and lakes, which causes pollution and can kill wildlife.
are there any byproducts made from recycled human waste?
The waste byproducts of hydrogen fuel cells are heat and water vapor. When hydrogen is converted into electricity in a fuel cell through a chemical reaction with oxygen, these are the only emissions produced, making fuel cells a clean and efficient energy source.
When hydrogen is burned, it produces water vapor as a waste product. No harmful emissions such as carbon dioxide or carbon monoxide are released when hydrogen is burned, making it a clean fuel source.
any kind of edible food, organic waste(excretory products)
Gold is a metallic element, not a process, therefore no gold does not have a waste product.
The waste product of electrolysis can vary depending on the substances being electrolyzed. For example, in the electrolysis of water, hydrogen gas is produced at the cathode and oxygen gas at the anode, with little to no waste. However, in the electrolysis of saltwater, chlorine gas can be released as a byproduct along with hydrogen. Overall, the specific waste products depend on the electrolytic solution and electrodes used.
