Sustainable Cogeneration Plant in Peru: A Model of Circular Economy and Social Development
This pre-project for a cogeneration plant in a strategic region of Peru aims to meet the growing energy demand driven by the development of major infrastructure. The project proposes a hybrid system that will valorize biomass and urban solid waste (USW) to produce electricity sustainably.
In addition to generating energy, the initiative focuses on a multifaceted valorization approach, producing high-quality
biochar and organic compost from the organic fraction of the waste. A distinctive feature is its deep commitment to social inclusion, actively seeking to hire
persons with disabilities (PwD) across the entire value chain. To this end, the project has a strategic alliance with the non-profit organization Yanapacc and plans to contact CONADIS.
The initiative is in the initial phase of seeking investment, with a required capital estimated between
$25.8M and $45.0M USD for its implementation and operation. Projected annual revenues are estimated to be between
$5.0M and $8.0M USD.
Researchers are invited to provide insights, experiences, and case studies on the following:
- Technology & Infrastructure: What are the most effective pre-treatment and sorting methods for mixed urban solid waste to optimize its use for energy conversion and composting? What are the main operational hurdles for a hybrid cogeneration system that uses thermal storage in a tropical climate?
- Socioeconomic Factors: What are the best practices for structuring a truly inclusive hiring program for people with disabilities in the context of industrial operations and waste collection logistics? What are the key social and regulatory challenges for securing long-term waste management agreements with municipalities and other entities?
- Financial Viability: How can the financial viability of such a project be de-risked beyond a simple reliance on energy sales, particularly by monetizing co-products and social benefits (like carbon credits)? Are there specific financial models or incentive programs in other developing nations that have successfully supported this type of integrated project?

The cogeneration plant project that combines biomass and municipal solid waste valorization for electricity generation represents a highly relevant and innovative model of sustainable development, particularly in the context of developing countries. Its focus on circular economy, social inclusion, and revenue diversification through co-product generation and potential carbon credits reflects a strong integration of environmental, social, and economic dimensions.
Technical Aspects: The use of a hybrid cogeneration system with thermal storage in tropical conditions requires careful engineering to minimize energy and operational inefficiencies caused by high humidity and temperature. A critical issue is the selection of optimal waste pre-treatment technologies—such as mechanical-biological treatment (MBT), source separation, and digestion of the organic fraction. Additionally, the implementation of digital systems to monitor waste composition and operational performance can significantly enhance plant efficiency.
Social Component: Inclusive employment of persons with disabilities (PwD) in the waste management sector is a challenging but highly valuable objective. It is necessary to develop specific job models adapted to PwD capabilities, ensuring continuous education, technical support, and partnerships with civil society organizations. For long-term sustainability, systemic support through regulatory frameworks and tax incentives is essential.
Financial Sustainability: To reduce investment risk, it is recommended to implement a multi-revenue stream model. In addition to electricity sales, income can be generated through the sale of biochar (which is used in agriculture as a soil enhancer), compost, waste disposal fees, and carbon credits. Experiences from Latin America—such as projects in Chile and Colombia—have shown that public-private partnerships and climate finance mechanisms (e.g., Green Climate Fund) can play a key role in closing the financing gap for such projects.
In conclusion, this project represents a significant step toward sustainable transformation of the energy and waste sectors in Peru, with strong potential for replication in other countries of the Global South. Further research into local regulatory frameworks, opportunities for community engagement, and identification of financial support instruments is highly recommended.
Apreciado Profesor Dragan Ugrinov,
Quisiera expresarle mi más sincero agradecimiento por su respuesta tan completa y detallada. Su análisis ha validado y enriquecido enormemente el anteproyecto, proporcionando una perspectiva experta y práctica sobre los desafíos técnicos, la crucial dimensión social de inclusión, y las estrategias de sostenibilidad financiera.
Me ha sido particularmente útil su recomendación de investigar a fondo los marcos regulatorios locales. Siguiendo su sugerencia, he profundizado en las normativas peruanas y he encontrado que:
- En la gestión de residuos, la Ley de Gestión Integral de Residuos Sólidos (DL 1278) y su reglamento no solo respaldan la valorización energética, sino que la priorizan. Esto confirma que nuestro proyecto se alinea perfectamente con la visión legal del país.
- En la cogeneración, el Reglamento de Cogeneración (DS 037-2006-EM) establece criterios técnicos claros de eficiencia que la planta debe cumplir para ser calificada, lo que nos permitiría acceder a beneficios como la prioridad en el despacho de energía. Esto es clave para asegurar la viabilidad económica a largo plazo.
- Para la inclusión laboral, la Ley General de la Persona con Discapacidad (Ley N° 29973) establece una cuota de empleo que podemos utilizar como base, fortaleciendo nuestra alianza con organizaciones como Yanapacc y CONADIS.
La información que ha compartido ha sido fundamental para pasar de una idea conceptual a una propuesta con bases legales y técnicas sólidas. Su contribución no solo fortalece el proyecto, sino que también nos orienta hacia los próximos pasos con mayor confianza.
Una vez más, muchas gracias por su tiempo y por compartir su conocimiento.
Atentamente,
Miguel Cuicapuza

In the context of molten salt thermal energy storage (TES) systems, what are the most critical technical and economic criteria for deciding between an above-ground and an underground tank configuration? Specifically, how do we quantify and compare the advantages of each approach in terms of thermal efficiency (heat loss), mitigation of salt solidification risks, long-term maintenance and repair costs, and reduction of environmental impact?
Miguel Cuicapuza
To decide between above-ground and underground tanks for molten salt thermal energy storage (TES), the key factors include:
1. Thermal Efficiency (Heat Loss):
- Above-ground: Higher heat loss due to external factors (low temperatures, wind, rain), requiring additional energy to maintain temperature.
- Underground: More stable ground temperature reduces heat loss and increases energy efficiency.
2. Risk of Salt Solidification:
- Above-ground: Greater temperature fluctuations increase the risk of salt solidification, which may lead to equipment failure.
- Underground: Stable ground temperature reduces the risk of solidification and allows better control over the molten salt.
3. Long-term Maintenance and Repair Costs:
- Above-ground: Susceptible to damage from external factors (corrosion, erosion), increasing maintenance costs.
- Underground: Less external damage, but harder access for inspections and repairs. Long-term, maintenance costs are lower due to system stability.
4. Environmental Impact:
- Above-ground: Greater visual and ecological impact on the surroundings (need for more space, erosion risks).
- Underground: Smaller impact on surface environment and ecosystem, but potential risks to groundwater or hydrogeological conditions.
Underground tanks are more energy-efficient and stable in the long term, but require a higher initial investment and more complex construction. Above-ground tanks are cheaper to build, but have higher maintenance costs and lower long-term efficiency.
@Abdissa
In my understanding, there are several key challenges that PWD faces in the integration of WtE in developing natios. To highlight some, first, many areas struggle with weak waste management systems that are inefficient and poorly governed. This makes it hard to implement new technologies effectively.
People with disabilities often find it difficult to access jobs because of negative attitudes, discrimination, and a lack of reasonable accommodations. High unemployment rates in this group stem from barriers to education and training, as well as social stigma. Additionally, inadequate infrastructure and limited access to technology make it hard for them to take on technical roles. There’s also low awareness among stakeholders about their responsibilities regarding waste management and disability rights. Social and family stigma further marginalizes people with disabilities, limiting their participation in both community and economic activities.
Dear Dragan,
Thank you very much for your comprehensive and well-structured answer. Your breakdown of the key factors is very helpful.
I find the point about long-term costs particularly interesting. You mention that underground tanks, despite their higher initial investment, can have lower long-term maintenance costs.
Could you elaborate on the maintenance and repair scenarios that would justify this difference? For example, what types of failures are more common and costly in above-ground tanks that would be mitigated by an underground configuration, and vice versa?
Estimada Abdissa Tegene Wolde,
Muchas gracias por esta respuesta tan perspicaz. Coincido plenamente en que los desafíos que usted menciona son fundamentales, especialmente en los países en desarrollo.
Me gustaría profundizar en un aspecto clave que usted ha señalado: el estigma social y la falta de conciencia de las partes interesadas. En su opinión, ¿qué tipo de intervenciones o programas de sensibilización han demostrado ser más efectivos para superar estas barreras y asegurar una participación significativa de las personas con discapacidad en el sector de la gestión de residuos y la energía?
Estimado Phil Geis,
Agradezco sinceramente esta pregunta tan perspicaz. Es, de hecho, el punto central de nuestra propuesta.
En este proyecto, el desafío no es elegir una prioridad, sino demostrar que los objetivos técnico y social no son excluyentes, sino que están intrínsecamente integrados y son interdependientes. La viabilidad a largo plazo de nuestro proyecto reside precisamente en esta sinergia.
- Lo Técnico hace posible lo Social: Nuestra solución técnica (la planta de cogeneración para la valorización de residuos) es el motor que genera el valor económico y ambiental. Es la tecnología la que nos permite convertir un pasivo ambiental en un activo, creando los recursos financieros necesarios para financiar el pilar social de la inclusión. El éxito de la operación técnica, respaldado por la experiencia de expertos como el Dr. Ugrinov y el Dr. Messini, es lo que garantiza la sostenibilidad económica del proyecto.
- Lo Social fortalece lo Técnico: La inclusión de personas con discapacidad no es una simple meta social, sino una estrategia de negocio. Al contar con un plan sólido de capacitación y un diseño de planta universal, mitigamos riesgos laborales, generamos un impacto positivo que atrae a inversores con enfoque ESG y creamos un valor que trasciende lo económico. Esta dimensión social nos diferencia y fortalece la resiliencia del proyecto en su conjunto.
En resumen, la máxima prioridad es la integración exitosa de ambos pilares. El proyecto no es un experimento social financiado por un objetivo técnico, ni una simple planta técnica con un "componente" social añadido. Es un modelo de negocio en el que la innovación técnica y la inclusión social se nutren mutuamente para generar un impacto sostenible y significativo.
