“…Furthermore, the COD removal also dropped from 76.1% to 58.7%, and the initial methanogenic activity (IMA) reduced from 1,042 to 602 mgCOD/d (see Table 6). Our results agreed with Nuchdang and Phalakornkule [51] and Panpong et al [52].…”

In Thailand, the palm oil industry produces a huge amount of palm oil mill effluent (POME), mostly used for electricity generation through biogas production. Co-digestion with other waste can further improve biogas yield and solve waste management problems. Most previous studies relied on biochemical methane potential (BMP) assay or batch co-digestion to obtain the optimal mixing ratio, ignoring the kinetic part or treat it for sole discussion of the results. This work directly uses mechanistic models based on Monod kinetics to describe the experimental results obtained from the co-digestion of POME (40 ml, BMP = 281.2 mlCH 4 /gCODadded)) with chicken manure (CM) (0–50 g) and crude glycerol (Gly) (0–10 ml). The best mixing ratio between CM and POME was 5 gCM: 40 mlPOME (BMP = 276.9 mlCH 4 /gCODadded). The best ratio for Gly and POME was 2 mlGly: 40 mlPOME (BMP = 211.9 mlCH 4 /gCODadded). Adding Gly only 2 mlGly/40 mlPOME doubled the amount of biogas. Hence, crude glycerol is a good substrate for on-demand biogas output. The co-digestion increases the methane output but with a decreased yield. A multi-substrate Monod model was developed based on the levels of digestion difficulty. A partial-least squared fitting was used to estimate its main parameters. All parameters included in the model passed the significant tests at a 95% confidence level. The model can describe the experimental results very well, predict observable state variables of batch co-digestion, and allow a simple extension for continuous co-digestion dynamics. A limited continuous experiment was conducted to confirm the applicability of the model parameters of POME digestion obtained from BMP tests to predict a continuous AD. The results show good potential but must be carefully interpreted. It is generally possible and practical to directly obtain design and operational parameters from BMP assays based on only accumulated biogas curves and initial and final COD/VS.

Wastewater from the food industry is increasingly recognized as a valuable source of energy and as a resource for new products and not as waste. The reutilization and valorization of wastewater contributes to combating water scarcity and to improve the energetic efficiency of treatment facilities. Moreover, it has the added benefit of reducing environmental impact and providing economically interesting added value products. This review discusses the most recent approaches for the valorization of food industry wastewaters of different origins (dairy, brewery, oil mill, fish, meat, among others) and the products obtained, from energetic resources such as biogas and biofuel to the recovery of biopolymers, pigments, phenolic compounds, and other added value products. A critical overview regarding the bottlenecks of large-scale implementation of resource recovery strategies, including up-scaling, quality and quantity of the effluent, legislation, and economic, environmental, and social issues related to the use of products derived from waste, is herein presented.
