Lasso SEMI-PE containers reinforce sustainability in the municipality of Mafra

Posted on by

Lasso™ has completed the installation of new semi-underground SEMI-PE containers in the municipality of Mafra, in Portugal, reinforcing the disposal capacity and efficiency of the urban waste collection system in various areas of the municipality.

In total, 64 semi-underground polyethylene Lasso™ containers were installed, distributed across 16 recycling points located in various parts of the municipality, covering the categories of mixed waste, packaging, paper, and glass. Capacities vary between 5 m³ for mixed waste, packaging, and paper, and 3 m³ for glass, ensuring an adequate response to local needs. Some locations also received containers for batteries with a minimum capacity of 8 liters, encouraging the correct disposal of this specific waste.

The equipment features recycled plastic coating (Wood Imitation), a standard lid, and a conventional and reinforced Masterbag extraction system, ensuring durability, safety, and ease of operation. Some units have been installed in the city center of Mafra, but also in parishes such as Ericeira, Malveira, and Venda do Pinheiro, among others.

Caring for the environment in this territory takes on special significance in a municipality like Mafra, known for its historical and natural heritage. The imposing Mafra Convent, classified as a World Heritage Site by UNESCO, is one of the country’s greatest cultural symbols and attracts visitors from all over the world, and the municipality is also marked by its strong connection to the sea, with beaches of high environmental quality and international recognition. Therefore, caring for a heritage that belongs to everyone is essential.

For Lasso, this installation represents another step in supporting municipalities in the transition to more efficient and sustainable collection systems. “The installation of these Lasso™ semi-underground containers in Mafra demonstrates the municipality’s commitment to modern and environmentally responsible solutions. We are proud to contribute to improving waste management in a municipality with such significant heritage and environmental value. These systems allow for greater capacity, better urban integration, and more comfort for users,” says Sofia Sampaio, commercial director of Lasso.

Lasso semi-underground containers installed in the Alpes-de-Haute-Provence Region

Posted on by

The Lasso™ brand continues to consolidate its presence in the French market, this time through the DLVAgglo – Durance Luberon Verdon Agglomération project implemented by Contenur, its distributor in France. The project involves the installation of semi-underground containers for the selective collection of urban waste in the agglomeration of communities located in the Alpes-de-Haute-Provence department, in southeastern France.

This region is distinguished by its strong natural and landscape component, marked by rural areas, small communities and a high environmental value, integrating mountainous areas, valleys and touristic areas of great importance. This context requires waste management solutions that combine robustness, functionality and integration into the public space, criteria that are the basis for Lasso’s waste containerization solutions.

To date, approximately 130 semi-underground concrete containers with a capacity of 5 m³ have been supplied, intended for the collection of four waste streams: mixed waste, packaging, paper, and glass.

The applied coatings have varied between “Rolled Pebble” and “Recycled Plastic,” with an “Image Coating” already implemented in one of the recycling banks, a solution visible in the most recent installations. The installation of five containers in painted concrete in the color “Forge” for the community of Gréoux-les-Bains is also planned for a future delivery.

The modular HDPE lids maintained a consistent configuration throughout the various phases of the project. For the mixed waste stream, lids with a double drum and a lid adapted for large producers were used, while the remaining streams use “Façade” vertical opening lids, also with a lid adapted for large producers.

For Sofia Sampaio, commercial director of Lasso, this project represents a strategic step in the brand’s international growth: “Projects like DLVAgglo demonstrate confidence in our solutions and reinforce the importance of the partnership with Contenur, which has been fundamental to consolidating our brand in France, through solutions adapted to the technical and territorial specificities of each region.”

With this project, Lasso reaffirms its commitment to developing sustainable, durable, and technically adapted solutions to meet the needs of each community, contributing to more efficient waste management in demanding urban and rural contexts.

Contentores semienterrados Lasso

Contenur, our partner in the French market, has completed the installation of 150 Lasso™ semi-underground containers in the territory of the Privas Centre Ardèche Community.

The project, which began a year ago, represents a milestone in the modernization of waste collection in this community, contributing to the improvement of citizens’ quality of life, the optimization of public services, and the promotion of more responsible environmental practices.

The new equipment allows for the selective collection of mixed waste, packaging, glass, and cardboard — the latter through specially adapted containers with a dedicated opening system.

Thanks to their versatility and landscape integration, Lasso semi-underground containers adapt harmoniously to different urban and natural contexts. The Privas Centre Ardèche region, which combines river, mountain, and city areas, exemplifies this integration capacity — ensuring efficient collection without compromising the aesthetics or environmental balance of public spaces.

The project is part of the long-term strategy of the Communauté d’Agglomération Privas Centre Ardèche, a territory strongly committed to ecological challenges and committed to the environmental and energy transition. Over the next three years, the initiative is planned to continue, with the aim of equipping the entire territory with this equipment.

Contenur and Lasso Eco Innovation thus continue to strengthen their role as reference partners in the implementation of efficient and ecological solutions for urban waste management in France.

Lasso SEMI DUO: two waste streams in a single container

Posted on by

The SEMI DUO, Lasso’s new semi-underground container, has now hit the market. It was developed specifically to help municipalities adapt to the collection of bio-waste. The Lasso SEMI DUO is an exclusive solution developed by Sopsa, with a unique feature that sets it apart from the rest: it is an innovative, bi-compartmentalized semi-underground container that allows two types of waste to be collected in the same container.

Designed to optimize collection space, this container is equipped with a modular double-opening lid that allows for various combinations of lids and openings – whether mats, vertical openings or single or double drums.

With two distinct openings and two independent bags, the new Lasso SEMI DUO stands out from other containers, allowing users to correctly deposit different waste streams without the risk of cross-contamination. SEMI DUO is particularly suitable for combining bio-waste/mixed waste, and works equally well with plastic/paper. It is also an interesting solution for adapting to existing semi-underground containers, allowing bio-waste to be collected without taking up additional space on public areas.

This innovative approach not only optimises urban space, reducing the need for multiple containers, but also simplifies collection logistics, making it more efficient and economically viable.

The new Lasso SEMI DUO is also compatible with intelligent waste management systems, such as access control systems or fill level probes. In addition, its modern and intuitive design encourages active participation by the population in waste separation, contributing to a cleaner and more sustainable environment. With its implementation, municipalities can take a significant step towards meeting recycling and organic recovery targets, ensuring waste management that is more in line with European environmental requirements.

“The introduction of Lasso SEMI DUO represents a concrete response to the challenges of selective collection, demonstrating that innovation and sustainability can go hand in hand to transform the way we manage our waste”, adds Sofia Sampaio, Sopsa’s commercial director for the international market.

Contentores hidráulicos Lasso instalados em Bucareste, Roménia

Following the installation of the new Sopsa factory in Romania, the first Lasso hydraulic underground containers are being installed in that country. The containers are destined for Sector 6 of the city of Bucharest and, to date, around 300 containers have been installed, in a project involving a total of 743 units.

The project for Sector 6 of the city of Bucharest integrates C4 hydraulic containers, with a Red Bee stainless steel column and drum, for the selective collection of mixed waste, plastic and packaging, paper and cardboard and bio-waste.

“The capital of Romania is now reorganizing its waste management, adapting it to the new European directives, and our Lasso containers will be fundamental to this process. The choice of hydraulic containers is due to the fact that they present all the advantages of a recycling bank with underground containers, without, however, the need for a crane”, says Sofia Sampaio, commercial director of Lasso for the international market.

The more than 700 new C4 hydraulic containers from Lasso are being produced at Sopsa’s new production unit, located north of Bucharest – Sopsa Inovatie Ecologica,Srl.
