A
concept of sustainable water-energy-environment nexus has been developed for thermal bioenergy conversion processes
as shown in Figures 1 and 2. Two case studies are performed in a biomass-fired combined heat and power (CHP) plant
and a waste incineration unit, which intend to approve and implement the concept. The main results from the case study on
stormwater issues in biomass-fired CHP plant show that the biomass fuel storage can play an important role in the sustainable
development for the water-energy-environment nexus. It has been proved that the water adsorption capacity of wood chips
can be used as a buffer to reduce water runoff, to extend the time for natural water evaporation, to receive the recycled runoff
water without significant impacts on fuel quality. The runoff water absorbed by the biomass fuels could increase heat recovery
and water reuse. The results also indicate that it is possible to achieve near zero water runoff and wastewater emissions in the
tested plant area by an integration of stormwater management with the bioenergy conversion processes. Another case study
is focused on a closed water loop in waste-to-energy (waste incineration) unit. The closed water loop can properly integrate
the thermal energy conversion with an efficient flue gas cleaning, cost-effective water treatment and energy-effective water
recovery. The investigation shows that it is possible to achieve a near zero wastewater discharge, which could also result in a
significant amount of water recovery for internal usage. The two case studies demonstrate that sustainable water-energy-nexus
could be set up in biomass energy conversion processes, which can provide good solutions, handle important issues associate
with water resource, energy efficiency and emissions to air and waters in bio energy conversion processes.
