There has been a significant increase in municipal solid waste worldwide, and thus, different public policies and targets have been established to improve the environment, which have presented a significant challenge in the efficiency of the waste collection process. Currently, municipalities in Chile do not have sufficient information to plan waste collection adequately to reduce the high costs incurred in this process. This study aims to analyze real data from the household solid waste collection system in the commune of Quinta Normal in Santiago, Chile. This data include measurements captured by GPS equipment mounted on a fleet of waste collection vehicles, as well as weighing records of these vehicles at the KDM transfer center, where the collected waste is disposed of. As a result of the integration of this data, 119 service zones were identified in the municipality for six collection days (Monday to Saturday), each with its respective annual household solid waste generation. These results contribute to improving the planning of household solid waste collection in Quinta Normal and thereby, optimizing bin locations and collection routes, and generating relevant spatial data related to household solid waste collection.

Limited productive and commercial coordination within rural high-Andean agricultural systems constitutes a structural constraint to sustainable income generation and the reduction of socioeconomic vulnerability. In these contexts, fragmented production, small operational scale, and weak integration into formal markets negatively affect technical efficiency and profitability. This study proposes an integrated strengthening model for the guinea pig value chain in the district of Huachis (Áncash, Peru), through the combined application of the Sustainable Livelihoods Approach and the Value Links methodology. The Sustainable Livelihoods framework enabled a quantitative assessment of human, physical, financial, natural, and social capital, identifying structural gaps directly linked to low productivity and limited household resilience. Baseline analysis revealed productivity levels approximately 30% below regional technical benchmarks and limited access to formal credit (less than 20% of producers). Based on this diagnosis, the Value Links methodology facilitated actor mapping, value flow analysis, and identification of coordination failures across chain segments. The proposed upgrading strategies project measurable outcomes, including a 25–35% increase in productivity per production unit, a 15–20% reduction in transaction costs through associative coordination, a 20% increase in net household income, and a 30% growth in formal or differentiated market participation. Additional targets include a 40% increase in producer formalization and strengthened collective governance structures. The proposed model enhances territorial economic sustainability and provides a replicable quantitative framework for value chain transformation in vulnerable rural environments.

The Physalis peruviana fruit has growing local availability and functional potential, motivating the need for safe and
efficient processing alternatives. This study evaluates the technical feasibility of implementing a small‑to‑medium canning plant by
analyzing industrial operations, productive capacity and sanitary requirements. A complete process route was specified, including reception,
sorting, washing with potable chlorinated water (50–200 ppm free chlorine, pH 6.5–7.5, 1–5 min), preparation of a 20 °Brix covering
medium, scalding at 80–85 °C, hot filling and ~15 min water‑bath pasteurization for acidic product safety, cooling and labeling. Productive
capacity was assessed based on a 100 kg/h kettle and an effective output of 800 kg/day (8 h), and compared against demand–supply
projections. Regulatory requirements were evaluated according to DS 007‑98‑SA and microbiological criteria applicable to processed foods.
The engineered route aligns with standard thermal processing practices and ensures product stability. Capacity analysis revealed
inconsistency between mass‑flow output (800 kg/day) and the target of 4 000 jars/day (~1 000 kg/day), indicating potential thermal or filling
bottlenecks. Market projections show sustained demand growth exceeding regional supply. Compliance with national sanitary regulations
and HACCP implementation is achievable within the proposed design. However, scaling requires reconciliation of throughput assumptions
and the incorporation of pilot‑scale microbiological validation to confirm process safety margins.
