“…Results from percolation were very similar regardless of the collection site (including deposits); the leachate drainage had a collectible volume 3 days after the start of water addition, until an outlet volume similar to the added volume was reached. This is indicative that Sargassum achieved its rehydration as occurring with other leachates generated in domestic solid waste deposits [32,33]. From this point, the volume generated stabilizes as a function of the aggregate volume, i.e., the percolation leachate depends on the milliliters of rain that can drain.…”

In this study, we evaluate the degradation by Sargassum spp. as a consortium in 2020 and 2021, and by species during 2021, collected at different distances from a coastline and in land deposits. The year 2021 had the largest leachate volume and the offshore site with the highest volume (60 mL/day) among five sites of collection. In relation to species’ leachate generation, S. fluitans reached 47.67 mL/day as its peak, which is earlier than S. natans (41.67 mL/day 14 days after S. fluitans). pH shows alkaline behavior and EC reflects the saline condition in the leachate, the consortium and species reaching values of pH 7.5 to 8.3 and 80 to 150 mS/cm of EC; the results do not show significant differences among sites, or between species. Despite a BOD/COD ratio of less than 0.1, the degradation process occurs as evidenced by the presence of leachate. The results confirm the existence of a variability in leachate production and the composition of Sargassum under the influence of factors such as the periodicity, site of collection, and proportions of species. Thus, even though these results emphasize leachate generation, knowing the limitations of leachate generation is crucial information for decision making on Sargassum storage and environmental management.

“…Treating MSW by recirculating leachate under anaerobic or aerobic conditions has shown to accelerate emissions in experiments at a lysimeter scale (Veeken et al, 2000, Kasam et al, 2013, Erses et al, 2008, Brandstätter et al, 2015a,b, Bilgili et al, 2007. By inducing (increased) water flow, leachate recirculation stimulates mixing of solutes and bacteria within the waste body which removes inhibitions and transport limitations for degradation (White et al, 2011).…”

Long-term emissions of Municipal Solid Waste (MSW) landfills are a burden for future generations because of the required long-term aftercare. To shorten aftercare, treatment methods have to be developed that reduce long-term emissions. A treatment method that reduces emissions at a lysimeter scale is re-circulation of leachate. However, its effectiveness at the field scale still needs to be demonstrated. Field scale design can be improved by theoretical understanding of the processes that control the effectiveness of leachate recirculation treatment. In this study, the simplest and most fundamental sets of processes are distilled that describe the emission data measured during aerobic and anaerobic leachate recirculation in lysimeters. A toolbox is used to select essential processes with objective performance criteria produced by Bayesian statistical analysis. The controlling processes indicate that treatment efficiency is mostly affected by how homogeneously important reactants are spread through the MSW during treatment. A more homogeneous spread of i.e. oxygen or methanogens increases the total amount of carbon degraded. Biodegradable carbon removal is highest under aerobic conditions, however, the hydrolysis rate constant is lower which indicates that hydrolysis is not enhanced intrinsically in aerobic conditions. Controlling processes also indicate that nitrogen removal via sequential nitrification and denitrification is plausible under aerobic conditions as long as sufficient biodegradable carbon is present in the MSW. Major removal pathways for carbon and nitrogen are indicated which are important for monitoring treatment effectiveness at a field scale. Optimization strategies for field scale application of treatments are discussed.

Sampah menjadi masalah serius di daerah perkotaan. Hal ini disebabkan oleh adanya kepadatan penduduk yang tinggi. Penimbunan sampah terus menerus akan menghasilkan pencemaran pada air lindi, baik yang berupa senyawa organik maupun anorganik termasuk logam berat. Pada penelitian ini dievaluasi penyebaran logam berat timbal (Pb) dan cadmium (Cd) dalam air lindi baik di air lindi maupun di kolam penampungan di TPA Pasuruhan, Kabupaten Magelang. Evaluasi kadar Pb dan Cd juga dilakukan dalam air sumur di sekitar TPA. Sampel air diambil di daerah air lindi inlet pada saluran irigasi, air lindi kolam tampung, sumur pantau dan sumur produksi. Kadar Pb dan Cd dianalisis spektrofotometri serapan atom dan dibandingkan dengan baku mutu Peraturan Menteri Lingkungan Hidup Kehutanan Republik Indonesia untuk air lindi. Baku mutu Peraturan Menteri Kesehatan Republik Indonesia untuk air sumur pantau dan sumur produksi. Hasil menunjukkan kadar Pb dan Pb dalam air lindi melebihi baku mutu. Kadar Pb dalam air lindi pada saluran inlet 0.83 mg/L dan kolam tampung 0,45 mg/L, sedangkan kadar Cd pada lindi inlet diperoleh hasil 0,05 mg/L dan kolam tampung 0,04 mg/L. Kadar Pb sumur pantau 0,05 mg/L dan sumur produksi 0,03 mg/L, sedangkan kadar Cd sumur pantau 0,008 mg/L dan sumur produksi 0,006 mg/L. Kadar logam Pb dan Cd dalam air sumur pantau dan air sumur produksi masih memenuhi baku mutu Kata Kunci: Air Lindi, Logam Berat
