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.

Contentores semienterrados Lasso em Temara, Marrocos

The first Lasso SEMI PE semi-underground containers have just been installed in Temara, a coastal city in Morocco, in a project carried out in collaboration with local distributor, Isotec Maroc. These are containers with a capacity of 1.5 m³, with a double metal ring, intended for the storage of mixed waste, installed in a new urbanization built in this Moroccan city recognized as a beach and golf destination.

Morocco is currently implementing a more sustainable waste management policy, in which Lasso semi-underground containers fit appropriately, given their characteristics of large capacity, robustness, durability and space optimization. One of the features that immediately pleased those responsible for the Temara project was the fact that waste is stored below ground, which prevents odors and pests and ensures greater urban hygiene.

“The Lasso SEMI adapt perfectly to the demands of our customers in Morocco and meet all the requirements for waste management needs in that country. The first containers have already been installed and we are sure that they are an excellent option”, says Sofia Sampaio, commercial director at Lasso for the international market.

Posted on by

In a joint project with Contenur, Lasso’s partner for the French market, 449 Lasso SEMI PE semi-underground containers have just been installed in the community of Mirande, in the Gers department, in the Occitania region, France.

These are 5m³ semi-underground containers, made of polyethylene with a recycled plastic finishing, with a metal tank and a Kinshofer extraction system. The containers are intended for the selective collection of unsorted waste, packaging and glass. The former are equipped with a double drum lid; those for packaging have a mat; and those dedicated to collecting glass have a vertical opening (Façade), for greater functionality and user comfort.

The containers are about to go into operation in Mirande and several other municipalities in the Gers department, a region located halfway between Toulouse and Bordeaux, between the sea and the ocean, close to the Pyrenees, a very popular destination in France and abroad thanks to its sunshine and concern for the preservation of its natural and cultural environment. “Lasso is proud to have its products represented in another leading region in France, a market with a high level of demand for its waste management”, highlights Sofia Sampaio, Lasso’s sales director for the international market.

Oeiras replaces old container columns with new White Bee solution

Posted on by

The municipality of Oeiras, in the center of Portugal, has taken another step towards improving its waste management system by replacing 140 old and obsolete container deposition columns with the innovative White Bee, a new solution developed by Lasso. The new White Bee features elegant deposition columns, which offer municipalities a modern and cost-effective solution to replace old and damaged containers while maintaining their existing underground infrastructure.

Lasso White Bee stands out for its simplicity and efficiency – the above-ground deposition column integrates seamlessly into existing underground waste storage systems, minimising the need for large-scale investment. Its stainless steel construction ensures longevity and wear resistance, making this equipment a practical choice for urban environments.

In addition, the White Bee can be equipped with intelligent waste management systems for data collection and eventual adoption of PAYT (Pay-As-You-Throw), optimising waste collection. “By launching this new solution, we reinforce our dedication to sustainable urban development and the cleanliness and hygiene of public spaces, by developing the best solutions to meet the needs of municipalities”, says Maria João Ferreira, Lasso’s commercial director for the national market.
