A detailed hourly thermal model was developed to simulate the thermal behavior of greenhouse components, incorporating all relevant heat transfer mechanisms. The model uniquely considers the presence of plants and their evapotranspiration processes, a crucial factor impacting energy and water usage within greenhouses. The model assessed the impact of six thermal screen materials on both heating and cooling loads, water consumption, and solar radiation transmission. Results revealed that implementing thermal screens leads to a substantial 41 % reduction in annual heating demand compared to greenhouses without screens. The impact on cooling loads varies significantly by screen type, ranging from an unfavorable 73 % increase to a beneficial 24.5 % reduction compared to conditions without screens. The white polyester screen achieved the best overall energy performance, reducing annual energy demand by 33.4 %. Additionally, the PH-66 (al) screen showed the highest water-saving potential, decreasing annual water consumption by 47 %.

For this, we first compared the removal of Cr (VI) by grape seeds (GS) and GSR-POE, obtaining that GSR-POE achieves higher removal efficiency than GS. Subsequently, it was determined that, with a particle size of 75 μm of GSR-POE and pH=2, the adsorption efficiency of Cr (VI) was favored, achieving the removal of 68.76 % of a simulated aqueous solution of Cr (VI) of 100 mg/L with a GSR-POE dosage of 0.8 g/L. The kinetic study showed that the GSR-POE adsorption process best fitted the pseudo-second order model, likewise, the Langmuir isotherm best described the process resulting in a maximum adsorption capacity of 169.48 mg/g. The thermodynamic study showed that the process is endothermic and spontaneous. The mechanisms involved in the adsorption process would be chemisorption and electrostatic attraction as there is a higher adsorption at pH=2 which is lower than the point of zero charge of GSR-POE (pH<sub>PZC</sub>= 4.95). Finally, a techno-economic analysis confirmed the economic viability and profitability of implementing a plant for GSR-POE production.
