Waste once is generated can not be destroyed. Waste can be minimized in term of both quantity and toxicity.
Equipment and flowsheet (Production process) modification in a bioprocess plant can minimize the waste generation.
Scientists are trying their best to develop novel bioprocessing plant with zero-waste . Recent advances include using less-costly inputs in the bio-process.Simplifying the waste streams, reducing their toxicity are the latest advances in bio industries.
For life science research organizations, hazardous waste management is, well, a hazard. Because hazardous waste disposal involves safety, regulatory, and financial risks, many labs assume it is cheaper and safer to do the work internally, handled personally by scientists or support staff. But this could be a mistake. Contrary to popular perception, outsourcing the work can be the less-risky option.

Waste can be convert into wealth. Presently many mining wastrs are recycling to extract valuable and toxic ingradiants. Microbial fuel cell is also an novel approach for utilisation of waste. Microbial reduction process could be a benevolent approach for treatment of oxidic mineral waste by using sulphidic mineral waste to extract metal values from both the types of mineral wastes. So many novel ap
proaches can be applied to convert waste into wealth
Many hazards are associated with industrial bioprocessing.some are highly pathogenic bacteria,viruses and genetically modified microorganisms etc.Bio waste like solid,liquid and gas from a bioprocessing plant must be decontaminated prior to release. Regulations relating to disposal and shipping of bio hazardous wastes must be followed. After decontamination,the hazardous waste disposed using same method applied to non biological waste.
The organic fraction of municipal solid waste can be converted into industrial chemicals biologically over night using a technology called Managed Ecosystem Fermentation. The current estimates for the value of the output is approximately $135 per ton. The products products include adhesives and volatile fatty acids. Once the feedstock for the adhesives is removed, then the volatile fatty acids as well as the toxic heavy metals can be extracted using ion resin exchange. This permits the recycling of the heavy metals. The water produced from the process can be used in cooling towers or other industrial applications.
