Biomass in Chile

Nueva Aldea, Chile Biomass energy

Nueva Aldea 2 is a 42 MW biomass power plant being built by Celulosa Arauco y Constitución S.A., a leading forestry company in Chile. It uses black residue from the pulping process as a renewable fuel source to cogenerate heat and electricity. The project prevents pollution and creates jobs in the region.

Goals of the project

The project consists of the construction of a new pulp mill with a surplus of 42 MW for the generation of electrical energy to the grid in the VIII region of Chile. The project uses biomass residues (black residue from the pulping process) as a renewable fuel source for the combined generation of heat and electricity. The Nueva Aldea Phase 2 project contributes to Chile's sustainable development by promoting the adoption of distributed electricity generation in a country traditionally dependent on the development of large-scale and centralized power plants. The use of highly efficient cogeneration equipment allows for better use of local and renewable resources, while reducing the use of fossil fuels in grid-connected power plants. This contributes to lower emissions of greenhouse gases and other air pollutants, in a country that has traditionally suffered from high levels of particulate air pollution.


Environmental benefits

The benefit of biomass energy is that biomass is renewable source of energy and it cannot be depleted. Biomass mostly derived from plants, that means as long as plants are going to be on this planet, biomass will be available as renewable energy source. Biomass helps reduce the amount of GHG that give more impact to global warming and climate change. The biomass emissions level is far smaller compared to fossil fuels. The basic difference between biomass and fossil fuels when it comes to amount of carbon emissions is: all the CO2 which has been absorbed by plant for its growth is going back in the atmosphere during its burning for the production of biomass energy. While the CO2 produced from fossil fuels is going to atmosphere where it increases greenhouse effect. Biomass is widely available energy source. The sources are from agriculture, forestry,fisheries, aquaculture, algae and waste. Many energy experts agree that when you combine economic and environmental character of energy sources biomass is on top of the list as one of the best energy sources.

Socio-economic benefits

The project activity will assist Chile's sustainable growth by providing electricity through biomass power generation, which is a clean and renewable energy source. The participants believe that biomass power generation constitutes a sustainable source of power generation that brings clear advantages to mitigate global warming. sing the available natural resources in a rational way, this project helps to promote the development of renewable energy sources in Chile. The project is a good example of the viability of electricity generation as a source of revenue not only to the pulp mill industry, but to all forest-related industries.

Project verification

The Clean Development Mechanism allows emission-reduction projects in developing countries to earn certified emission reduction (CER) credits, each equivalent to one tonne of CO2. These CERs can be traded and sold, and used by industrialized countries to a meet a part of their emission reduction targets under the Kyoto Protocol.

The mechanism stimulates sustainable development and emission reductions, while giving industrialized countries some flexibility in how they meet their emission reduction limitation targets.

United Nations’ Sustainable Development Goals

As a Regreener your money directly goes towards supporting projects that are in line with the United Nations Sustainable Development Goals. Here are the goals recognised by this project:

Ensure access to affordable, reliable, sustainable and modern energy.

Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation

Ensure sustainable consumption and production patterns

Take urgent action to combat climate change and its impacts

Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss
