Environmental innovation that serves society
SERVICES

In the area of waste management, ENT adopts a preventative focus, centred on generating less waste and achieving better management. Our main focus has been municipal waste, but we have some experience on construction and demolition waste, industrial waste and mineral oils.

Most of our projects are commissioned by Public Administrations, from very practical projects for Local Authorities to very specific consulting reports for the European Commission or on the framework for European projects, including projects for regional and national authorities (strategies, programmes, design of specific policy instruments, etc.). We also collaborate with universities or research centres and with environmental NGOs, amongst others.

Within the area of waste management, we highlight our experience in economic aspects (costs and economic implications of waste policies) and in the design and evaluation of economic and fiscal policies (waste charges , pay-as-you-throw schemes , taxes on landfilling and incineration, deposit-refund schemes, fee-rebate systems, etc.).

We have also produced various waste management plans for local authorities. In particular, we have a lot of experience in the design and implementation of separate door to door collection schemes .

Another priority area of work is waste prevention, where we have produced numerous waste prevention plans for local entities and projects consisting in implementing specific measures. A specific waste flow in which we have paid particular attention is nappies. Another area in which we have specialized are projects to prevent food waste.

An important part of our work is the framework of research projects, which later derive in a good number of technical and scientific publications.
