Hesus Store, when the digital is put to the service of the circular economy of the building

It is one of the key sectors in the field of circular economy. The biggest waste producer in France-more than 70% of the total, according to figures published by the Ademe in 2016, the CONSTRUCTION penalty, however, to achieve the objectives set by the law of energy transition, namely, a rate of utilization of 70% in 2020.

Quarantine of millions of tonnes from each year of the building only (excluding public works), a maximum of one-half (depending on region) is now recycled, recognizes the French building Federation (FFB). A delay on which the reality of the daily life of the building weighs a lot: a relatively low awareness of existing solutions, in the face of the schedules tight, the site managers are the most simple, in defiance often of the circular economy, which yet, in this sector, is particularly cost-effective.

A startup born in 2012, Hesus, proposes to lift the brake, by pulling a hyphen between the CONSTRUCTION sector and the industry of the value of a resource through its digital platform, Hesus Store – recent evolution of the previous version named Soldating, limited to dredged inert. Usable from a computer, a smartphone or a tablet, it allows you to report in a few clicks need, is to get rid of a cut (of materials and land, polluted or not), or to obtain an embankment, and this, taking into account the pace of construction. As a dating site, the platform detects a correspondence between applications, opening up the possibility of placing an order and ensuring a response within 24 hours. It also provides data on the reduction of the carbon impact generated, the rate of recovery of waste products, the impact of the back-and-forth of the dump on residents…

Advance collaborative

“We centralize the information in order to optimize the time management of the drivers of construction sites,” stresses Benjamin Draoulec, head of Hesus Store. In a more general way, the platform allows the”anticipation collaborative” that is the basis of any project of circular economy, further specifies Emmanuel Cazeneuve, founder and president of Hesus. The startup relies on industry solutions partners: Suez, which deals with the eventual clean-up of land, and Cemex, a company specialized in the production and marketing of aggregates and concrete, which supports the management of dredged spoil. In the framework of the development of new services, imposed and facilitated by the digital revolution, large groups and startups are not in opposition, but should rather collaborate in a same ecosystem, recalls Philippe Maillard, director general, recycling and recovery of Suez.

Additional services offered by the platform are also offered by other startups, such as Dashdoc, which simplifies the execution phase by dematerializing the letters car. And a contract already signed with Bouygues ensures deposits and opportunities.

A change of culture

In the Face of the challenges of waste management for the CONSTRUCTION industry -particularly in view of the work of the Grand Paris, the Grand Paris Express alone is expected to generate more than 45 million tonnes of dredge spoil by 2030-a change in culture more deep is needed, however, feel the actors of the sector. “We must stop talking about wastes and speak to material,” points out Jean Bergouignan, director-general of the activities concretes ready-to-use of Cemex, especially as the inevitable development towards an “increase in the complexity of their composition” will demand action from closer to the construction site to characterize them and determine their destination, focusing on the short loop to reduce the costs and the nuisance of transport. “Sorting at the source is always the preferred solution,” agrees Philippe Maillard, and advocating for the interest including economic recruitment of specialists to assist the foremen in its implementation and in its management.

Another fundamental challenge: the emergence close to the real sectors of the recycling, sometimes still in their infancy in this sector, says Philippe Maillard: “users of resources transforms are sometimes rare. The regulatory changes may play a significant role: “It is necessary to encourage the use of a percentage of recycled material,” underlines the director general recycling and recovery of Suez. “It is better to put a little recycled in all the concretes rather than a lot of recycling in little concrete”, grade John Bergouignan who, by opposing the creation of real obligations, considers the existing regulations “still too complex and too rigid”. “It would be better to insert the use of recycled materials as one of the criteria of public procurement”, he adds.

In his eyes, the game is worth the candle: in a country where the use of land is the subject of the competition, the challenge of the circular economy in the CONSTRUCTION industry is also the one to “restore to the citizens of the area”, he says:

“Careers redeveloped, we will be able to make forests, fields, cities: what we want.”
