Sustainable engineering solutions


Sustainability is not a design constraint, but an opportunity to generate innovative solutions

What is enigreen?

It is our vision of engineering that considers, at all times, the potential benefits and problems in terms of environment, economy and society throughout the design lifecycle, in line with the recent EU initiatives


Our main goal is to minimize adverse impacts and maximize benefits by implementing sustainable engineering solutions

Discover the benefits

As green engineering leaders, Enigest can help you take advantage of sustainable designs 

  • Minimization of pollution generation at source
  • Reduction or elimination of waste
  • Minimization of negative environmental impact
  • Better quality of life for all species
  • Protection and restoration of natural systems
  • Economic growth and competitiveness

Our principles

Our firm is committed to a series of principles, understood as good practices, that are the basis of enigreen, which we implement in all the projects and services that we develop in each of our fields of work.

  • All material and energy inputs and outputs are as inherently nonhazardous as possible
  • Maximum reduction of pollution and waste, it is better to prevent than to treat
  • Waste treatment processes designed to minimize energy consumption and materials use
  • Works and construction processes designed to maximize mass, energy, space and time efficiency
  • Complexity balance: embedded entropy and complexity is viewed as an investment when making design choices on recycle, reuse, or beneficial disposition
  • Targeted durability, not immortality, is a design goal
  • Optimal disigns to meet the needs, without excesses
  • Minimization of material diversity
  • Designs that include integration and interconnectivity with available energy and material flows
  • Infrastructures designed for performance in a commercial “afterlife”
  • Material and energy inputs renewable over the entire lifecycle of the infrastructure

enigreen services

Although enigreen philosophy is linked to all aspects of our firm, we have great experience in developing different works more specifically related to the environment

  • Flora and fauna studies
  • Faunistic connectivity studies
  • Environmental restoration projects
  • Integrated landscape studies
  • Environmental assessments
  • Urban environmental reports
  • Plans and projects environmental impact studies
  • Construction Environmental Management
  • Natural environment management and planning
  • Environmental cartography and Geographic Information Systems (GIS)
  • Forest fire prevention plans 
  • Design of treatment systems for the first flush rainwater (with hydrocarbons presence)


Our methodology is based on our passion, integrity, and exceptional teamwork. Every project receives the attention it deserves
