About us

Mission and history

Having started its operations in the management and exploitation of sanitary landfills of municipalities associations, namely the collection and treatment of Municipal Solid Waste (MSW), BioSmart has been diversifying its activity areas, responding to the needs and expectations of customers regarding environmental protection and public health.

Thus, these companies´ activity holds a complementary nature since, together, they aim to return nature to its original purity, combining the preservation of natural resources with technology in a perfect alliance between sustainable growth and development.

Today, BIOSMART keeps on growing, namely due to its internationalization strategy in Angola and Brazil. In order to ensure this sustained growth, BIOSMART relies on the following values:

  • Rigour in the provided services and products;
  • Companies´ and partnerships´ stability;
  • Projects´ innovation;
  • Teams´ know-how;
  • Closeness to the internal and external customer;
  • Immediate response;
  • Environmental sustainability;
  • Social responsibility.


In order to bring BIOSMART project to its present stage, much ground has been covered and the present business model has been updated in terms of permanent improvement. In this context, the following is a close picture of the path travelled for more than a decade.

In June 1998, along with the launching of the landfill of Abrantes, Solurbe - Tratamento de Resíduos Sólidos is established - and, in 2004, was renamed Lena Ambiente, S.A. In 2019, this one was renamed and gave origin to BIOSMART.  

 Following the first experience with the landfill of Abrantes, sold in 2006, it is exactly in the waste management that BIOSMART firstly proceeds operating, namely with the following infrastructures:

  • From May 2000 to July 2001: Landfill of Abrantes and respective transfer station at Ponte de Sôr, covering five municipalities (Avis, Alter do Chão, Ponte de Sôr, Fronteira and Sousel);
  • From June 2000 until today: Landfill of Almeirim which includes two other transfer stations and three eco-centres;
  • From October 2002 until today: Ordinary Industrial Waste (OIW) Landfill of Leiria which, at the time, was the second facility of this kind to operate in the country. This infrastructure is part of Lena Ambiente, through Lena Ambiente´s share in Resilei, S.A.;
  • From April 2003 until today: OIW Landfill of Castelo Branco, the third of its class on the national level, for which operation and management BIOSMART is responsible;
  • From January 2004 until today: Landfill of Évora and respective sorting plants, as well as four other sorting facilities, four transfer stations, thirteen eco-centres and the concession of selective collection of waste.
    BIOSMART´s involvement in these infrastructures comes in the wake of an invitation by AMDE (Associação de Municípios do Distrito de Évora - Association of Municipalities of Évora´s District) which enabled the establishment of GESAMB, EIM (inter-municipal company);
  • From January 2005 until today: Non-hazardous waste landfill of Beja, which goal is to meet the needs (by Alentejo´s and Algarve´s producers) regarding this type of waste.
    Also in 2005, the waste management infrastructure in Almeirim are now run by Ecolezíria - a inter-municipal company included in the RESIURB system since 2000 and strengthened in 2005 following the arising of BIOSMART and another private partner.
