Waste

Benefits

Lower logistics costs = more resources for treatment

Mechanical Treatment (MT) units allow the unsorted waste received (without selective collection) to be separated into three major fractions: recyclables, organics and rejects.

Logistics

How logistics pays for treatment

Once separated, these fractions can be valorized to recover materials on an industrial scale and generate renewable energy within the urban area.

The investments needed to build and operate MT units are made possible by the financial resources saved by streamlining logistics services.

Shorter distances

MT units for unsorted waste are installed within the urban area, much closer than the distant sanitary landfills.

Less volume transported

Reducing the volume of waste hauled to distant landfills makes each garbage truck more productive, as it completes its collection routes faster.

Efficiency

Same population, smaller fleet

This streamlining of logistics directly improves the efficiency of waste collection and transport, since it makes it possible to serve the same population with a fleet of garbage trucks at least 30% smaller than the fleet currently in use.

By delivering these major savings in collection and transport (lower CAPEX and OPEX for garbage trucks), a significant part of the resources needed to build the industrial units that valorize each fraction of unsorted waste becomes available.

Spending is thus redistributed between essential public cleaning services and treatment, reducing the material sent to landfills and making the system more efficient.

Benefits

Other social, environmental and economic benefits

When local governments (municipalities) prioritize building industrial Mechanical Treatment units for unsorted waste, numerous benefits can be achieved, such as:

Longer-lasting landfills

A longer lifespan for existing sanitary landfills.

New jobs

Both in the manual sorting stage of industrial Mechanical Treatment (MT) units and in the industries that manufacture new recycled products.

Organic compost

The main input of organic farming, which supports production on small farms and healthy food for the whole population.

Carbon in the soil

Organic compost retains moisture and fixes carbon in the soil.

Fewer trucks on the road

Less garbage truck traffic, which means fewer traffic jams in cities and also lower CO₂ emissions from all light vehicles and shorter travel times, whether people use public or private transport.

New industries

Enables new industries that use recyclable waste as raw material, promoting the conservation of biodiversity and natural resources by minimizing the use of existing deposits and avoiding the exploitation of new ones.

Energy from rejects

Depending on the region, renewable energy can be generated by combusting (burning) the reject fraction (the non-recyclable fraction of urban waste) in a Reject Energy Recovery Plant (CRER), or by producing refuse-derived fuel (RDF) for the cement industry.

Electric fleet

Allows garbage trucks and transfer trailers to be electric, charged with the energy generated at the CRER.

An alternative for the organic fraction

If there is no agricultural demand for organic compost in the project region, the organic fraction can be sent to bioenergy sanitary landfills to generate electricity or produce biofuel (biomethane) for the fleet of garbage trucks and trailers.

Carbon targets

By reducing methane and CO₂ emissions, Aiesse Ambiental’s projects help industrialized countries meet their carbon emission reduction targets (NDCs) faster and at lower cost, while generating carbon credits that can become an additional source of revenue when traded on the international market or on the Brazilian domestic market, which is currently being regulated.
