Knowing precisely w h chemicals a ich re stocked is vital for optimising usage
Water Water is a valuable and increasingly expensive resource, so reducing its use should be considered whenever applicable. For instance, researchers should not use water-jet vacuum pumps because they use huge amounts of precious drinking water, and they should only use closed-circuit cooling water loops for cooling equipment/experiments. Minimising the use of deionised water is also important, as it is very costly to produce (both in terms of energy consumption and the use of chemicals for purification).
Waste Waste tends to be much more expensive than it immediately appears, as costs are usually split into different budgets; hence, no one is fully aware of the total figures. Getting rid of broken, obsolete, or surplus equipment – often sitting idle for years, taking up space that could be better utilised for productive research – is one way to reduce waste. Another is optimising recycling rates and procedures, such as: • Providing convenient recycling facilities (consumables and packaging waste). • Implementing careful separation of clinical/hazardous waste. • Ensuring that suppliers collect containers/packaging. • Implementing charts, reuse tables, or similar mechanisms to ensure that unwanted equipment, materials, etc., can be donated, exchanged, sold or disposed of safely.
